  • Quiz: At end of the lecture

Diabetes

  • Definition: Endocrine disorder characterized by chronic hyperglycemia (high blood glucose levels).
  • Causes:
    • Insufficient insulin production by the pancreas
    • Increased insulin resistance by body cells
  • Signs & Symptoms (3 Ps):
    • Polydipsia: Increased thirst
    • Polyphagia: Increased hunger
    • Polyuria: Increased urination
  • Other Symptoms:
    • Weight loss
    • Dehydration
    • Fruity breath odor
    • Kussmaul respirations (increased rate & depth of respiration)
    • Nausea and vomiting
    • Lethargy
    • Warm, dry skin
    • Hint: Warm and dry, sugar's high
  • Management:
    • Carbohydrate-controlled diet
    • Insulin & oral antidiabetic agents (Type 1 diabetes requires insulin; Type 2 can use oral agents)
    • Goal: HGB A1C level under 7%
  • Somogyi Phenomenon:
    • Morning hyperglycemia due to overnight hypoglycemia
    • Prevention: Consume a snack with nightly insulin dose

Hypoglycemia

  • Definition: Blood glucose level under 70 mg/dL
  • Causes:
    • Excess insulin
    • Decreased food intake
    • Exercise
    • Excess alcohol
  • Signs & Symptoms:
    • Hunger
    • Irritability
    • Confusion
    • Diaphoresis (sweating)
    • Headache
    • Shakiness
    • Blurred vision
    • Pale, cold, clammy skin
    • Hint: Cold and clammy, need some candy
  • Severe Symptoms:
    • Seizure
    • Coma
  • Management:
    • If conscious, consume 15 grams of a readily absorbed carbohydrate (e.g., 4 oz juice/soda, 8 oz milk)
    • Recheck blood glucose after 15 minutes
    • If still under 70 mg/dL, consume another 15 grams of carbohydrate and recheck after 15 minutes
    • Once glucose > 70 mg/dL, consume a snack with protein and carbohydrate (e.g., cheese and crackers)
    • Hint: 15-15 rule (15 grams of carbohydrate, wait 15 minutes)
