Type 1 Diabetes Reference¶
Overview¶
Type 1 diabetes is an autoimmune disease in which the immune system destroys insulin-producing beta cells in the pancreas, resulting in little or no insulin production and requiring lifelong insulin replacement. Unlike Type 2 diabetes (which involves insulin resistance), T1D cannot be prevented or reversed through diet or lifestyle changes.
Historical Context and Medical Evolution¶
Terminology Evolution¶
The understanding and naming of diabetes has evolved significantly over time:
Ancient to Early Modern Era: - "Diabetes mellitus" (Latin for "sweet urine") recognized since antiquity - Distinguished from diabetes insipidus (different condition with similar urination symptoms) - Type 1 and Type 2 not differentiated until the 20th century
20th Century Distinctions: - "Juvenile diabetes" or "juvenile-onset diabetes" used because most T1D diagnoses occurred in childhood - "Insulin-dependent diabetes mellitus" (IDDM) introduced to distinguish from non-insulin-dependent diabetes (NIDDM) - 1990s-present: "Type 1 diabetes" became standard terminology, recognizing that onset can occur at any age - "Juvenile diabetes" now considered outdated but still used by some older organizations and in casual conversation
Modern Understanding: - T1D recognized as autoimmune condition distinct from metabolic Type 2 - LADA (Latent Autoimmune Diabetes in Adults) identified as slow-onset T1D in adults, often misdiagnosed as T2D - Greater awareness that T1D can develop at any age, not just childhood
Pre-Insulin Era: A Death Sentence¶
Before 1922, a Type 1 diabetes diagnosis was essentially a death sentence:
Life Expectancy: - Children diagnosed with T1D typically survived only 1-3 years - Most died from diabetic ketoacidosis (DKA), wasting away as their bodies could not use glucose - Young patients often appeared skeletal, their bodies consuming muscle and fat for energy
Frederick Allen's Starvation Diet (1910s-1921): - Dr. Frederick Allen developed the only treatment that extended life: severe caloric restriction - Patients consumed as few as 400-500 calories daily - Diet consisted mainly of lean protein and vegetables; carbohydrates virtually eliminated - Extended survival from months to 1-3 years but resulted in constant hunger and physical wasting - Families watched children slowly starve while trying to keep them alive long enough for a cure - Some patients died of starvation rather than DKA
Hospital Wards: - Diabetes wards in children's hospitals were heartbreaking places - Rows of emaciated, dying children too weak to play - Parents visiting knowing their child would not survive
The Miracle of Insulin (1921-1922)¶
The discovery of insulin remains one of medicine's greatest triumphs:
The Discovery: - July 27, 1921: Dr. Frederick Banting and medical student Charles Best, working at the University of Toronto, successfully isolated insulin from dog pancreases - Dr. J.J.R. Macleod provided laboratory space; biochemist James Collip purified the extract for human use - Banting and Macleod received the 1923 Nobel Prize (controversially excluding Best and Collip from the honor)
First Human Treatment: - January 11, 1922: Leonard Thompson, a 14-year-old dying of diabetes at Toronto General Hospital, became the first person treated with insulin - Initial injection caused severe allergic reaction (impure extract) - January 23, 1922: Collip's purified extract administered successfully - Leonard Thompson lived another 13 years, dying at 27 of pneumonia
Transformation of Diabetes Wards: - Within months, children who had been near death were gaining weight and leaving hospitals - Witnesses described it as watching resurrections - Insulin rapidly became available worldwide by 1923 - Eli Lilly partnered with University of Toronto for mass production
Insulin Evolution¶
First Generation (1920s-1970s): - Animal-source insulin (beef and pork pancreases) - Required multiple daily injections - Variable purity led to allergic reactions and injection site problems - "Regular" and NPH (intermediate-acting) insulins developed
Human Insulin Era (1978-present): - 1978: First synthetic human insulin produced via recombinant DNA technology - 1982: Humulin (Eli Lilly) became first FDA-approved genetically engineered pharmaceutical - Reduced allergic reactions and improved absorption
Insulin Analog Era (1990s-present): - Rapid-acting analogs (Humalog 1996, Novolog 2000, Apidra 2004) with faster onset - Long-acting analogs (Lantus 2000, Levemir 2005, Tresiba 2015) with flatter, longer profiles - Greater flexibility in meal timing and dosing
Technology Evolution¶
Injection Methods: - 1920s-1960s: Glass syringes requiring sterilization, large-gauge reusable needles - 1960s-1970s: Disposable plastic syringes with finer needles - 1985: First insulin pen (NovoPen) offered convenience and accuracy - Modern pens: Pre-filled, disposable, half-unit dosing available
Insulin Pumps: - 1974: First insulin pump (Biostator) was the size of a microwave, used only in hospitals - 1978: First wearable pump developed but still large and cumbersome - 1983: MiniMed (now Medtronic) introduced first widely-used portable pump - 1990s-2000s: Pumps became smaller, more reliable, with more features - 2000s: Tubeless "patch" pumps (Omnipod 2005) offered alternative to tubed systems - Modern pumps: Smartphone-controlled, automated insulin delivery
Blood Glucose Monitoring: - Pre-1960s: Urine testing only (delayed, imprecise indicator) - 1965: First blood glucose test strip (Ames Dextrostix) required visual color matching - 1970: First portable blood glucose meter introduced - 1980s-1990s: Home meters became common; still required large blood samples, 45-second+ wait times - 2000s: Meters became smaller, faster (5 seconds), requiring tiny blood samples
Continuous Glucose Monitors (CGM): - 1999: First CGM (Medtronic CGMS) provided data only for healthcare providers to review retrospectively - 2004: First real-time CGM for patients (Medtronic Guardian) - 2006: Dexcom entered market with STS - 2008: Abbott FreeStyle Navigator offered improved accuracy - 2010s: CGMs became smaller, more accurate, longer-wearing (7-14 days) - Modern CGMs: Integration with smartphones, sharing with family/caregivers, trend arrows, predictive alerts
Automated Insulin Delivery (Closed-Loop Systems): - 2016: Medtronic 670G became first FDA-approved "hybrid closed-loop" system - Combined CGM with pump to automatically adjust basal insulin - DIY community (OpenAPS, Loop) pioneered closed-loop systems before commercial options - 2020s: Multiple commercial options available; still require user input for meals - Future direction: Fully automated "artificial pancreas" systems in development
Medical Attitudes and Stigma Across Eras¶
Early Insulin Era (1920s-1950s): - Miraculous survivor status for people with T1D - Strict medical paternalism; doctors dictated every aspect of diet and activity - Rigid meal schedules and exchange-based diet systems - Limited expectations for normal life, careers, or parenthood
Mid-Century (1950s-1970s): - Growing recognition that people with T1D could live full lives - Still significant restrictions (many careers, military service prohibited) - Pregnancy considered extremely high-risk; some doctors advised against it - Children often sent to diabetes camps for intensive management education
Complications Era (1980s-1990s): - DCCT trial (1983-1993) proved tight control reduced complications - Shift toward intensive management with multiple daily injections or pumps - Increased pressure on patients for "perfect" control - Growing awareness of "diabetes burnout" and psychological burden - Complications (blindness, amputation, kidney failure) still common in those diagnosed before modern management
Modern Era (2000s-present): - Technology enabling tighter control with less burden - Recognition of diabetes distress and mental health impacts - Shift from blame-focused to support-focused care - Growing understanding that "control" is never perfect despite best efforts - Advocacy for language changes: "person with diabetes" vs. "diabetic"; "checking" vs. "testing" blood sugar
Race, Gender, and Class Disparities¶
Access to Insulin: - Insulin pricing crisis in the United States makes life-saving medication unaffordable for many - Rationing insulin (taking less than prescribed due to cost) causes preventable deaths - Black, Hispanic, and low-income populations disproportionately affected by cost barriers - Other wealthy nations provide insulin free or at minimal cost through healthcare systems
Technology Access: - Insulin pumps and CGMs significantly improve outcomes but cost $6,000-$12,000+ annually - Insurance coverage varies; many face denials or high out-of-pocket costs - Racial and socioeconomic disparities in who receives advanced technology - Black children with T1D less likely to use pumps than white children with equivalent insurance
Outcome Disparities: - Black Americans with T1D have higher A1C levels and complication rates on average - Contributing factors include healthcare access, insurance coverage, implicit bias in care, and social determinants of health - Lower-income individuals face barriers to healthy food access, stable housing, and consistent healthcare
Historical Exclusions: - Until relatively recently, T1D excluded individuals from military service, many commercial driving jobs, pilot licenses - Some restrictions have eased with technology improvements (FAA now allows some pilots with T1D)
Era-Specific Implications for Series Characters¶
Logan Weston (diagnosed ~2007, age 11-12): - Diagnosed in an era when insulin pumps and CGMs existed but weren't yet standard - Likely started on multiple daily injections before transitioning to pump therapy - Came of age as CGM technology rapidly improved (Dexcom G4/G5/G6 during his teens and twenties) - Has never known the days of boiling syringes or animal insulin - Benefits from modern rapid-acting analogs and automated insulin delivery - Still faces American insulin pricing concerns despite being a physician - His career in medicine gives him both advantages (knowledge, access) and stressors (demanding schedule, sleep disruption) - Post-accident complications (SCI) create unique challenges for diabetes management that require specialized adaptation
WHAT IS TYPE 1 DIABETES?¶
Definition: Autoimmune disease in which the immune system destroys insulin-producing beta cells in the pancreas. Results in little or no insulin production, requiring lifelong insulin replacement.
Key Points: - Autoimmune condition: Body attacks itself - Not caused by diet or lifestyle: Can't be prevented - Different from Type 2: T1D is insulin deficiency; T2D is insulin resistance - Onset usually childhood/young adult: But can develop at any age - Lifelong condition: No cure, requires daily management - Life-threatening if untreated: DKA (diabetic ketoacidosis) can be fatal
What Happens: 1. Immune system destroys beta cells in pancreas 2. Pancreas produces little or no insulin 3. Without insulin, glucose can't enter cells 4. Blood sugar rises (hyperglycemia) 5. Cells starve despite high blood sugar 6. Body breaks down fat and protein for energy (ketones produced) 7. Ketones accumulate → diabetic ketoacidosis (DKA) → death if untreated
Why Insulin Is Critical: - Insulin is the "key" that unlocks cells to let glucose in - Without insulin, glucose stays in bloodstream - Cells can't get energy despite abundant glucose - Like starving with food all around but locked away
TYPE 1 VS. TYPE 2 DIABETES¶
Type 1 Diabetes (T1D)¶
Cause: Autoimmune destruction of insulin-producing cells Insulin Production: Little to none Age of Onset: Usually childhood/young adult (but any age possible) Prevention: Not preventable Treatment: Insulin (injections or pump) required for survival Prevalence: ~5-10% of all diabetes cases Other Names: Juvenile diabetes (outdated), insulin-dependent diabetes Risk Factors: Genetic predisposition, environmental triggers unclear
Type 2 Diabetes (T2D)¶
Cause: Insulin resistance (cells don't respond to insulin properly) Insulin Production: Initially normal or high, may decline over time Age of Onset: Usually adulthood (but increasingly younger) Prevention: Lifestyle factors can reduce risk Treatment: Diet, exercise, oral medications; insulin sometimes needed Prevalence: ~90-95% of all diabetes cases Risk Factors: Obesity, sedentary lifestyle, family history, age, ethnicity
Why the Distinction Matters¶
Stigma: - T2D blamed on lifestyle (often unfairly) - T1D "not your fault" but T2D "you did this to yourself" - Both harmful narratives - Both are chronic diseases requiring management
Treatment: - T1D always needs insulin - T2D may not need insulin (at least initially) - "Just exercise and watch your diet" doesn't work for T1D - Conflating them leads to dangerous advice
For Logan: - T1D since childhood - Zero insulin production - Insulin pump and CGM non-negotiable - Can't "diet and exercise" his way out of it
BLOOD GLUCOSE BASICS¶
Normal Range¶
Target Range: 70-180 mg/dL (varies by individual and situation) Fasting (Morning): 80-130 mg/dL After Meals (2 hours): <180 mg/dL Bedtime: 100-140 mg/dL
A1C (Average Blood Sugar Over 3 Months): - Non-diabetic: <5.7% - Prediabetic: 5.7-6.4% - Diabetic: ≥6.5% - Target for T1D: <7% (individualized) - Logan's likely goal: <7% but challenging with SCI complications
Hypoglycemia (Low Blood Sugar)¶
Definition: Blood glucose <70 mg/dL
Mild Symptoms (70-54 mg/dL): - Shakiness, trembling - Sweating - Hunger - Irritability, mood changes - Dizziness - Confusion - Rapid heartbeat
Moderate Symptoms (54-40 mg/dL): - Difficulty concentrating - Weakness - Blurred vision - Slurred speech - Drowsiness - Uncoordinated movements
Severe Symptoms (<40 mg/dL): - Seizures - Loss of consciousness - Death (if prolonged and untreated)
Treatment: - Rule of 15: 15g fast-acting carbs, wait 15 minutes, recheck - Glucose tablets (preferred - exact dose) - Juice, regular soda - If unconscious: Glucagon injection (emergency) - Never give food/drink if unconscious
Causes: - Too much insulin - Skipped or delayed meal - More exercise than usual - Alcohol without food - Illness
For Logan: - Dexcom alerts when dropping - Always carries glucose tabs - Charlie knows glucagon protocol - Medical alert bracelet critical
Hyperglycemia (High Blood Sugar)¶
Definition: Blood glucose >180 mg/dL
Symptoms: - Increased thirst - Frequent urination - Blurred vision - Fatigue - Headache - Difficulty concentrating - Nausea (if severe)
Severe Hyperglycemia: - Diabetic ketoacidosis (DKA) - medical emergency - Fruity-smelling breath - Rapid breathing - Confusion - Abdominal pain - Vomiting - Loss of consciousness - Death if untreated
Treatment: - Insulin correction dose - Hydration - Check for ketones - If DKA developing: Emergency room
Causes: - Insufficient insulin - Illness, infection - Stress - Certain medications - Pump malfunction - Insulin expired or damaged
DIABETIC KETOACIDOSIS (DKA)¶
What Is DKA?¶
Definition: Life-threatening complication when body breaks down fat for energy due to lack of insulin. Produces ketones, which make blood acidic.
Mechanism: 1. No insulin → glucose can't enter cells 2. Cells starve → body breaks down fat 3. Fat breakdown produces ketones 4. Ketones accumulate in blood 5. Blood becomes acidic (metabolic acidosis) 6. Severe dehydration from frequent urination 7. Electrolyte imbalances 8. Can lead to coma, death
Symptoms¶
Early: - High blood sugar (usually >250 mg/dL) - Increased thirst and urination - Nausea - Fatigue
Progressive: - Vomiting - Abdominal pain - Fruity-smelling breath (acetone) - Rapid, deep breathing (Kussmaul respirations) - Confusion, difficulty concentrating
Severe: - Severe dehydration - Loss of consciousness - Coma - Death
Treatment¶
Hospital Care Required: - IV insulin - IV fluids (rehydration) - Electrolyte replacement (potassium critical) - Monitoring - Treating underlying cause (infection, illness)
Recovery: - Can take 12-24 hours - Exhausting - Risk of cerebral edema (especially children)
Prevention¶
- Never skip insulin
- Check ketones when sick or BG >250 mg/dL
- Sick day management plan
- Extra hydration during illness
- Contact provider if ketones present
For Logan¶
Childhood Experiences: - Likely had DKA at diagnosis - Possibly other episodes when young (learning management) - Terrifying for child and parents
Accident Emergency (December 2025): - Insulin pump destroyed in crash - Unconscious for 18 days - IV insulin in ICU - DKA risk managed by medical team - Pump replaced after discharge
INSULIN BASICS¶
Types of Insulin¶
Rapid-Acting (Bolus): - Onset: 10-15 minutes - Peak: 1-2 hours - Duration: 3-5 hours - Examples: Humalog, Novolog, Apidra - Uses: Mealtime insulin, correction doses
Short-Acting: - Onset: 30 minutes - Peak: 2-3 hours - Duration: 6-8 hours - Example: Regular insulin - Uses: Mealtime (less common now)
Intermediate-Acting: - Onset: 1-2 hours - Peak: 4-12 hours - Duration: 12-18 hours - Example: NPH - Uses: Basal coverage (less common with pumps)
Long-Acting (Basal): - Onset: 1-2 hours - Peak: Minimal to none (flat action) - Duration: 20-24+ hours - Examples: Lantus, Levemir, Tresiba - Uses: Background insulin (if not using pump)
Ultra-Long-Acting: - Duration: Up to 42 hours - Example: Tresiba - Uses: Very stable basal insulin
Basal vs. Bolus¶
Basal Insulin: - Background insulin - Keeps blood sugar stable between meals and overnight - With pump: Continuous micro-doses - With injections: Long-acting insulin once or twice daily
Bolus Insulin: - Mealtime insulin - Covers carbohydrates eaten - Correction insulin (brings high BG down) - Rapid-acting insulin
Total Daily Insulin: - Basal: ~40-50% of total daily dose - Bolus: ~50-60% of total daily dose - Varies by individual
INSULIN DELIVERY METHODS¶
Multiple Daily Injections (MDI)¶
Method: - Long-acting insulin (1-2 times daily) - Rapid-acting insulin before meals and for corrections - Injections with syringe or insulin pen
Pros: - No device to wear - Less expensive than pump - Simple technology
Cons: - Multiple injections daily (4+ per day) - Less flexibility with meals and activity - Can't adjust basal insulin easily
Insulin Pump¶
Method: - Small computerized device worn on body - Delivers rapid-acting insulin continuously (basal) - User programs bolus doses for meals/corrections - Infusion set (small catheter) inserted under skin every 2-3 days - Pump attached to infusion set via tubing OR tubeless (pod)
Pros: - No multiple daily injections - Precise insulin delivery (0.025 unit increments) - Easy to adjust basal rates - Flexible eating and activity - Calculates insulin doses based on settings
Cons: - Expensive - Device attached to body 24/7 - Site infections possible - Pump malfunction = rapid DKA risk - Learning curve
Logan's Pump: - Worn since childhood (after initial diagnosis period) - Destroyed in accident (December 2025) - Emergency glucose monitoring while unconscious - Replaced after discharge - Integral to his diabetes management
Closed-Loop Systems (Artificial Pancreas)¶
Method: - Insulin pump + CGM communicate - System automatically adjusts insulin based on CGM readings - User still enters carbs for meals - Reduces burden of constant decision-making
Examples: - Medtronic 670G, 770G, 780G - Tandem t:slim X2 with Control-IQ - Omnipod 5
Benefits: - Better blood sugar control - Reduced hypoglycemia - Less mental load - Safer overnight
Limitations: - Still not a cure (still need to count carbs) - Expensive - Technology can fail - Not perfect (human pancreas is remarkable)
CONTINUOUS GLUCOSE MONITORING (CGM)¶
How CGM Works¶
Technology: - Small sensor inserted under skin - Measures glucose in interstitial fluid (not blood) - Transmits readings wirelessly to receiver/phone/pump - Updates every 1-5 minutes - Wears for 7-14 days depending on brand
Brands: - Dexcom (G6, G7) - Freestyle Libre (1, 2, 3) - Medtronic Guardian
Logan's CGM:
Main article: Logan's Continuous Glucose Monitor
- Dexcom continuous glucose monitor (G6 from diagnosis in 2019, upgraded to G7 in 2023)
- Closed-loop system integrated with insulin pump
- Synced to Apple Watch and iPhone (real-time readings)
- Alerts for high/low blood sugar
- Charlie can see readings via Dexcom Follow app (Julia and Nathan had access during adolescence)
- Critical for safety with his other disabilities, especially post-SCI (reduced autonomic warning signs)
- Back of upper arm primary site; avoids abdomen post-SCI
Benefits of CGM¶
Real-Time Information: - See current blood sugar - See trend (rising, falling, stable) - Predict highs/lows before they happen
Alerts: - Low blood sugar warning - High blood sugar warning - Urgent low alarm (critical) - Trend alerts (dropping fast, rising fast)
Better Control: - See how food, exercise, stress affect BG - Make informed decisions about insulin - Reduce A1C - Prevent severe hypos
Safety: - Alerts during sleep - Shares data with caregivers - Reduces fear of hypoglycemia
Limitations¶
Not Perfect: - Lag time (~10-15 minutes behind blood glucose) - Sensors can be inaccurate - Need to calibrate (some models) - Still need fingerstick confirmations sometimes
Practical Issues: - Expensive - Adhesive problems (sensors falling off) - Skin irritation - Device to wear 24/7
DAILY MANAGEMENT¶
Morning Routine¶
- Check CGM reading
- Check overnight trends
- Correct high BG if needed
- Calculate breakfast carbs
- Dose bolus insulin
- Eat within appropriate time (rapid-acting timing)
- Monitor BG after meal
Throughout the Day¶
Before Each Meal: - Check current BG - Count carbohydrates - Calculate insulin dose (carb ratio + correction factor) - Dose insulin - Eat
Between Meals: - Monitor CGM trends - Correct highs as needed - Treat lows immediately - Adjust for activity
Exercise: - Check BG before, during, after - May need to reduce insulin or eat extra carbs - Delayed hypoglycemia possible (hours later) - Patterns vary by type of exercise
Nighttime¶
Before Bed: - Check BG (target 100-140 mg/dL) - Correct high or treat low - Ensure CGM working - Set alerts
Overnight: - CGM monitoring - Risk of hypoglycemia (dawn phenomenon) - Basal rates may need adjustment - Charlie checks Logan's CGM if alarm
Carbohydrate Counting¶
Why It Matters: - Carbs raise blood sugar more than protein or fat - Insulin dose based on carb intake - Accurate counting = better control
Insulin-to-Carb Ratio: - How many grams of carbs covered by 1 unit of insulin - Example: 1:10 ratio = 1 unit covers 10g carbs - Varies by individual and time of day - Must be tested and adjusted
Correction Factor: - How much 1 unit of insulin lowers blood sugar - Example: 1:50 = 1 unit drops BG by 50 mg/dL - Used to bring high BG back to target
Complex Math: - Every meal requires calculation - Carbs in food + current BG + active insulin = dose - Mistakes can cause hypo or hyperglycemia - Mental burden constant
COMPLICATIONS OF TYPE 1 DIABETES¶
Acute Complications¶
Hypoglycemia: - Can cause seizures, loss of consciousness, death - Risk with any insulin use - Scary for person and loved ones
DKA (Diabetic Ketoacidosis): - Life-threatening - Requires hospitalization - Can develop quickly
Hyperosmolar Hyperglycemic State (HHS): - Extremely high BG (>600 mg/dL) - Severe dehydration - Rare in T1D (more common in T2D)
Chronic Complications (Long-Term)¶
Retinopathy (Eye Damage): - High blood sugar damages blood vessels in retina - Leading cause of blindness in adults - Screening: Annual eye exams - Prevention: Tight glucose control
Nephropathy (Kidney Damage): - High blood sugar damages kidney filters - Can lead to kidney failure, dialysis - Screening: Annual urine test, kidney function tests - Prevention: Glucose control, blood pressure management
Neuropathy (Nerve Damage): - High blood sugar damages nerves - Peripheral neuropathy: Numbness, tingling, pain in feet/hands - Autonomic neuropathy: Affects digestion, heart rate, bladder, sexual function - For Logan: Already has neuropathic pain from SCI; diabetes adds risk
Cardiovascular Disease: - Heart attack, stroke risk significantly increased - High blood sugar damages blood vessels - For Logan: Widowmaker heart attack in late 50s (diabetes likely contributor)
Foot Problems: - Neuropathy = loss of sensation - Can't feel injuries - Poor circulation - Infections can lead to amputation - Critical with SCI: Logan can't feel feet; double risk
Skin Conditions: - Infections more common - Slow healing - Diabetic dermopathy
Gastroparesis: - Delayed stomach emptying from nerve damage - Makes blood sugar control extremely difficult - Nausea, vomiting, bloating
Preventing Complications¶
Tight Glucose Control: - A1C <7% (individualized) - Reduces all complication risks - DCCT study: Tight control reduces: - Retinopathy by 76% - Nephropathy by 50% - Neuropathy by 60%
But Tight Control Has Costs: - Increased hypoglycemia risk - Mental burden of constant management - Burnout risk - Not always achievable
Other Prevention: - Blood pressure control - Cholesterol management - Don't smoke - Regular screening - Foot care
SPECIAL SITUATIONS¶
Illness (Sick Days)¶
Blood Sugar During Illness: - Usually rises (stress hormones) - May need more insulin - DKA risk increases
Management: - Never stop insulin (even if not eating) - Check BG every 2-4 hours - Check ketones if BG >250 mg/dL - Hydrate - Contact provider if ketones present - ER if vomiting, can't keep fluids down, ketones high
For Logan: - Immunocompromised (asplenic) = more infections - Any fever >101°F = emergency - Sick days more complex with multiple conditions
Surgery¶
Perioperative Management: - NPO (nothing by mouth) = no food = BG changes - Stress of surgery raises BG - Anesthesia affects BG - IV insulin often needed - Close monitoring required
Logan's Accident: - Emergency surgery - Pump destroyed - 18-day coma - IV insulin throughout - Complex management with TBI, other injuries
Alcohol¶
Effects: - Lowers blood sugar (liver busy processing alcohol, not releasing glucose) - Delayed hypoglycemia (hours later, even overnight) - Impaired judgment = missed symptoms - Never drink on empty stomach - Always eat with alcohol - Check BG before bed
Pregnancy (For Women with T1D)¶
Risks: - Birth defects if poor control at conception - Miscarriage - Preeclampsia - Large baby (macrosomia) - Neonatal hypoglycemia
Management: - Extremely tight control (A1C <6%) - Frequent monitoring - Insulin needs change throughout pregnancy - High-risk pregnancy care
Exercise¶
Blood Sugar Effects: - Usually lowers BG (muscles use glucose) - Can raise BG (intense exercise, stress hormones) - Delayed hypoglycemia possible (up to 24 hours later)
Management: - Check BG before, during, after - May need to reduce insulin or eat extra carbs - Carry fast-acting glucose - Wear medical ID
For Logan: - Pre-accident: Track athlete, managed BG carefully - Post-accident: Exercise limited by SCI - PT and wheelchair use still affect BG
TECHNOLOGY FAILURES¶
Insulin Pump Malfunctions¶
Types of Failures: - Pump error/malfunction - Infusion set clogged or kinked - Insulin gone bad (heat, expired) - Site infection preventing absorption - Pump dropped/damaged
Consequences: - No basal insulin = rapid BG rise - DKA can develop in 4-6 hours - Medical emergency
Backup Plan: - Always have backup insulin (long-acting + rapid) - Syringes or pens ready - Know how to calculate doses without pump - Contact provider or ER
Logan's Accident: - Pump destroyed in crash - Emergency situation - Medical team managed with IV insulin - New pump after discharge
CGM Sensor Failures¶
Types of Failures: - Sensor error - Sensor falling off - Inaccurate readings - Signal loss (receiver out of range)
Consequences: - No real-time glucose data - No alerts - Increased hypo/hyper risk - Anxiety from loss of safety net
Backup: - Fingerstick blood glucose meter always - Extra sensors available - Know how to manage without CGM
Battery/Power Issues¶
Pump Battery: - Must be charged or have fresh batteries - Low battery = pump stops = DKA risk
CGM Receiver/Phone: - Need to keep charged - Chargers everywhere (home, car, work)
For Logan: - Medical equipment requires power - Multiple devices to manage (pump, CGM, wheelchair) - Backup plans essential
EMOTIONAL AND PSYCHOLOGICAL IMPACT¶
Daily Mental Burden¶
Constant Vigilance: - 180+ decisions per day about diabetes - No breaks, no vacations - Never "off duty" - Exhausting mentally
Fear: - Hypoglycemia (especially at night, while alone) - Long-term complications - Technology failures - Medical emergencies
Guilt and Shame: - "Bad" numbers feel like personal failure - Blamed for highs/lows - Should have done better - Internalized stigma
Diabetes Burnout¶
What It Is: - Feeling overwhelmed by constant management - Apathy toward diabetes care - Skipping insulin, not checking BG - Giving up on tight control
Risk Factors: - Years of management (chronic condition fatigue) - Depression, anxiety - Lack of support - Unrealistic expectations
Treatment: - Therapy (diabetes-specialized if possible) - Loosen control temporarily (prevent complete disengagement) - Support groups - Address depression/anxiety - Self-compassion
For Logan: - Childhood diagnosis = decades of management - Post-accident: Diabetes + SCI + pain + PTSD - Burnout risk high - Medical knowledge helps but also adds pressure
Diabetes Distress¶
Different from Burnout: - Acute emotional response to diabetes challenges - Frustration, anger, fear - Can be triggered by specific events
Common Triggers: - Unexpected highs/lows - Technology failures - Healthcare provider dismissal - Complications developing - Others' ignorance about diabetes
Mental Health Comorbidities¶
Depression: - 2-3x higher in T1D population - Affects diabetes management (apathy, neglect) - Diabetes worsens depression (burden, fear) - Needs treatment (both conditions)
Anxiety: - Fear of hypoglycemia - Fear of complications - Perfectionism about control - Hypervigilance
Eating Disorders: - Higher rates in T1D (especially women) - "Diabulimia": Skipping insulin to lose weight - Life-threatening - Very difficult to treat
For Logan: - History of severe depression (post-accident) - Suicidal ideation during recovery - Diabetes likely compounded mental health struggles - Managing multiple chronic conditions = cumulative burden
SOCIAL AND PRACTICAL CHALLENGES¶
Stigma and Misconceptions¶
Common Myths: - "You ate too much sugar" (not how T1D works) - "Just take insulin and you're fine" (so much more complex) - "You can't eat that" (can eat anything with proper insulin) - Confusing T1D with T2D (different diseases)
Impact: - Feeling judged - Having to educate everyone - Unsolicited advice - Accusations of non-compliance
Food and Social Situations¶
Challenges: - Counting carbs at restaurants (guessing) - Social pressure to eat ("Just have some cake!") - Explaining why you're not eating (low BG, waiting for insulin) - Delayed meals = hypoglycemia risk - Alcohol pressure
For Logan: - Decades of practice - Confident in management - Doesn't explain to everyone - Charlie understands and supports
School and Work¶
Accommodations Needed: - Access to food/drink anytime (treat lows) - Test blood sugar anytime - Access to bathroom (high BG = frequent urination) - Breaks as needed - Safe place for pump/CGM supplies
Discrimination: - Employers/schools may not understand - Seen as liability - Denied opportunities - Fired or suspended for managing diabetes
For Logan: - Physician = understands medical conditions - Self-employed (Weston Centers) = no discrimination - Models disability accommodation for staff - Patients see his pump/CGM = representation
Driving¶
Concerns: - Hypoglycemia while driving = impaired like drunk driving - Must check BG before driving - Pull over if feeling low - Some jurisdictions require medical clearance
For Logan: - Drives with hand controls (SCI accommodation) - CGM alerts to hypoglycemia risk - Glucose tabs in car always - Decades of safe driving
Healthcare System¶
Costs: - Insulin: $300-1000/month without insurance - Pump: $5000-8000 upfront, supplies ongoing - CGM: $200-500/month - Test strips, lancets, ketone strips - Doctor visits, labs - Total: $10,000-20,000+ per year
Insurance Battles: - Prior authorizations - Denied coverage for "not medically necessary" (pump, CGM) - Formulary restrictions (can only get certain insulins) - Quantity limits - Appeals required
Insulin Rationing: - Can't afford insulin - Ration supply (skip doses, use less than needed) - Life-threatening - People die from rationing
For Logan: - Physician = good insurance - Financial access to technology - Privilege of affordability - Advocates for patients who can't afford care
LOGAN'S SPECIFIC EXPERIENCE¶
Childhood Diagnosis¶
Likely Presentation: - Classic symptoms: Thirst, frequent urination, weight loss, fatigue - Possibly DKA at diagnosis (common if not caught early) - Hospitalization for stabilization - Education for Logan and parents - Life forever changed
Early Management: - Multiple daily injections initially (standard at the time) - Fingerstick blood glucose testing (no CGM initially) - Learning carb counting - Pediatric endocrinologist - Parents managing initially, Logan learning gradually
Transition to Pump: - Likely in late childhood or early teens - Improved control - More flexibility - Lifelong pump user by age 17
Teen Years¶
Challenges: - Independence vs. parental monitoring - Social pressures (food, alcohol, fitting in) - Sports (track athlete) = complex BG management - Growth spurts = insulin needs changing - Diabetes burnout risk (common in teens)
Track Athlete: - Pre-workout BG checks - Adjusting insulin for exercise - Recovery nutrition - Building endurance despite diabetes - Proving diabetes doesn't limit him
The "Weston Double" Pattern Emerges:
During his senior year at Edgewood High School, Logan developed a dangerous pattern that would follow him throughout his academic and professional life: brilliant intellectual performance immediately followed by medical crisis. This pattern, later termed the "Weston Double" by his medical students and residents, revealed how Logan's perfectionism and refusal to acknowledge his body's limitations created predictable cycles of achievement and collapse.
The most dramatic instance occurred during a dual enrollment presentation at CCBC Essex in spring 2025. Logan stood at the podium with thirty-two slides of immaculate research on neuroplasticity in adolescent brain development--thirty percent of his final grade for Professor Harrington's course. His Dexcom alarmed throughout, first softly, then urgently: 54 mg/dL and dropping. He muted the alarm without checking the reading. Words began fragmenting mid-sentence. His note cards became indecipherable. His hands shook visibly. He collapsed at the podium, the accumulated debt of months of four-hour nights, skipped meals, and ignored warnings finally collecting in front of twenty-seven students who watched the brilliant performance end not with a conclusion but with darkness.
This pattern revealed several critical aspects of Logan's relationship with his diabetes: - Perfectionism interfering with medical management: Logan intellectually understood hypoglycemia, could explain the physiology in clinical detail, and had the tools to prevent crashes. But in high-pressure academic situations, finishing the performance perfectly mattered more than his safety. - Treating body as disposable: Logan viewed his body as a vehicle for his mind rather than an integrated part of himself, pushing through medical needs to prove he wasn't limited by diabetes. - Social cost of excellence: The incident reinforced classmates' view of Logan as "too much"—brilliant but somehow wrong for displaying that brilliance, disabled but expected to hide any sign of struggle. - Shame around medical needs: Being escorted from class after a brilliant presentation felt like failure, as if his body's needs invalidated his intellectual achievements.
The pattern continued throughout senior year. After his advanced seminar presentation on epigenetics—another graduate-level performance that amazed his professor—Logan went home and crashed for four hours, his body demanding payment for the intellectual exertion.
First Week at Howard University (Fall 2025):
When Logan began at Howard University at age seventeen, the "Weston Double" pattern followed him immediately. His first week brought unexpected challenges that complicated his diabetes management:
- Dining hall difficulties: Uncertain carb counts in cafeteria food made bolusing accurately nearly impossible. Logan's obsessive structure around diabetes management, which had been challenging at home with familiar foods, became fraught when navigating new meals with unpredictable nutritional information.
- Disrupted routines: New sleep schedules, different physical activity levels, unfamiliar campus layout requiring more walking—all affected his blood sugar in ways he couldn't always predict.
- Stress and homesickness: Emotional adjustment to college, separation from Julia and Nathan, pressure to prove he could handle independence—all impacted his blood sugar control. Stress raises blood sugar; anxiety can trigger drops. Logan experienced both simultaneously.
- Brilliant performance, medical cost: The pattern from high school continued. Logan would deliver exceptional work in classes, his intellectual capacity immediately evident to professors like Dr. Evelyn Graves and Dr. Alicia Monroe. But the performances came at a cost: blood sugar crashes, exhaustion so profound he could barely function afterward, his body demanding payment for the mental exertion.
- Late-night phone calls to Julia: Logan would call his mother after everyone else had gone to sleep, his voice carefully controlled but Julia could hear beneath it the struggle. He admitted feeling overwhelmed, that his diabetes was harder to manage without familiar routines and her oversight.
The first week at Howard revealed that Logan hadn't yet learned to balance achievement with self-preservation—a lesson his body would keep trying to teach him through increasingly severe consequences.
The Accident (December 12, 2025, Age 17)¶
Immediate Crisis: - Pump destroyed in crash - Unconscious, can't manage diabetes - ICU: IV insulin (tight glucose control) - Stress of trauma = elevated BG - Multiple organ systems failing
18-Day Coma: - Medical team manages diabetes - Parents unable to help (Logan always self-managed) - Continuous glucose monitoring critical - Insulin drip adjusted frequently - One less thing Nathan/Julia had to worry about (medical team handled it)
Recovery: - New pump after discharge - Managing diabetes + SCI + pain + TBI - Depression affecting diabetes care - Technology helping when Logan couldn't
Adulthood¶
Current Management: - Dexcom CGM synced to Apple Watch - Insulin pump (replaced after accident) - Decades of experience - Near-expert level knowledge - Manages diabetes alongside SCI, chronic pain, cardiac issues
Professional Life: - Physician who uses medical devices visibly - Models disability in medicine - Patients see his pump, CGM = representation - "I already believe you" = understanding chronic illness from inside - Diabetes informs his empathy and clinical practice
Personal Life: - Charlie knows his diabetes inside and out - Shares CGM data with Charlie (safety) - Charlie checks if Logan's alarm goes off - Mutual caretaking (both have chronic conditions) - Diabetes just one of many conditions they manage
Long-Term Complications Risk¶
Current (30s-40s): - Likely no major complications yet (decades of good control) - Annual screening (eyes, kidneys, nerves, feet) - Monitoring closely given SCI (can't feel feet)
Future (50s-60s): - Heart attack in late 50s (diabetes likely contributor) - Cardiovascular disease risk from decades of diabetes - Neuropathy risk (combined with SCI nerve damage) - Retinopathy possible - Kidney function monitoring
Prevention Efforts: - Tight glucose control (CGM + pump help) - Medical knowledge = early intervention - Access to excellent healthcare - But decades with diabetes = risk accumulates
WRITING TYPE 1 DIABETES IN SCENES¶
Technology Details¶
CGM: - Small sensor (usually upper arm or abdomen) - Check reading on phone/watch - Alerts vibrate or sound - Trend arrows (rising, falling, stable) - Share data with caregivers
Insulin Pump: - Small device (size of pager/phone) - Worn on waistband, in pocket, clipped to clothing - Tubing connects to infusion set (or tubeless pod) - Screen shows BG, insulin on board, pump settings - Beeps for alarms, reminders
For Logan: - Dexcom sensor visible sometimes (arm) - Apple Watch displays BG constantly - Pump tucked in pocket/waistband (discreet) - Medical alert bracelet mentions diabetes
Daily Management Scenes¶
Before Meals: - Glance at CGM reading - Mental calculation (carbs, correction) - Pull out pump, dose insulin - Seamless, automatic (decades of practice)
Low Blood Sugar: - CGM alarm (urgent low) - Shaky, sweaty, irritable - Grab glucose tabs - Wait for BG to rise - Frustration at interruption
High Blood Sugar: - Alert on watch - Dose correction insulin - Drink water - Continue with day - Annoyance but routine
Emotional Moments¶
Burnout: - Staring at pump with exhaustion - "I'm so tired of this" - Wanting a day off (impossible) - Guilt over wanting reprieve
Fear: - Hypoglycemia at night - Charlie checking his CGM - Worry about long-term complications - Seeing complications in patients (knowing his risk)
Technology Failure: - Sensor error at worst moment - Pump alarm during important meeting - Feeling betrayed by devices - Backup plan kicking in
Avoiding Ableist Tropes¶
Don't: - "Poor Logan, suffers from diabetes" - Miracle cure storylines - "Forgot to take insulin" (not how it works - constant management) - Eating candy/sweets causing problems (properly dosed insulin = can eat anything) - "Diabetic" as entire identity
Do: - Show diabetes as part of life (not defining feature) - Technology as helpful but imperfect - Mental burden acknowledged - Competence despite chronic condition - Logan's medical expertise partly from lived experience - Representation matters (disabled doctor)

- JDRF (Juvenile Diabetes Research Foundation)
- American Diabetes Association
- Diabetes Control and Complications Trial (DCCT)
- Endocrinology research on T1D management
