Treatment of Hypoglycemia in Non-Diabetic Individuals

For non-diabetic individuals with hypoglycemia, administer 15-20g of oral glucose as first-line treatment, followed by a meal or snack once blood glucose normalizes. 1

Immediate Treatment Protocol

For Conscious Patients

  1. First-line treatment: Administer 15-20g of fast-acting carbohydrates 2, 1

    • Preferred options: Glucose tablets (if available)
    • Alternatives: Any form of carbohydrate containing glucose
    • Avoid high-fat foods as they slow glucose absorption
  2. Follow-up steps:

    • Recheck blood glucose after 15 minutes 2
    • If hypoglycemia persists, repeat carbohydrate treatment
    • Once blood glucose normalizes, consume a meal or snack to prevent recurrence 2

For Unconscious Patients or Those Unable to Take Oral Carbohydrates

  1. Administer glucagon 3:

    • Adults and children >25kg or ≥6 years with unknown weight: 1mg subcutaneously or intramuscularly
    • Children <25kg or <6 years with unknown weight: 0.5mg subcutaneously or intramuscularly
    • If no response after 15 minutes, repeat dose while waiting for emergency assistance
  2. Seek immediate medical attention after glucagon administration 3

Special Considerations

Monitoring and Follow-up

  • Schedule follow-up within 1-2 weeks to identify underlying causes 1
  • Assess for recurrent episodes and modify treatment plan accordingly
  • Consider referral to specialists for persistent or unexplained hypoglycemia

Risk Factors to Consider

  • Critical illness
  • Cortisol insufficiency
  • Genetic causes
  • Medications (particularly those that affect insulin secretion)
  • Post-bariatric surgery status

Underlying Causes Assessment

While immediate treatment focuses on raising blood glucose, identifying and addressing the underlying cause is essential for long-term management:

  • Medication-induced: Review all medications for potential hypoglycemic effects
  • Endocrine disorders: Consider insulinoma, adrenal insufficiency, hypopituitarism
  • Post-bariatric hypoglycemia: Common in patients who have undergone gastric bypass
  • Autoimmune hypoglycemia: Associated with insulin antibodies
  • Non-islet cell tumors: Can secrete insulin-like factors
  • Critical illness: Particularly liver disease, sepsis, or malnutrition

Patient Education

Educate patients at risk for hypoglycemia about:

  • Recognition of symptoms: shakiness, irritability, confusion, tachycardia, hunger
  • Proper treatment with fast-acting carbohydrates
  • Importance of carrying a glucose source at all times
  • Need for follow-up meals or snacks after treating hypoglycemia

Pitfalls to Avoid

  1. Misdiagnosis: Hypoglycemic symptoms are non-specific and can mimic neurologic, psychiatric, or cardiovascular disorders 4
  2. Overtreatment: Excessive carbohydrate consumption can lead to rebound hyperglycemia
  3. Delayed treatment: Prolonged hypoglycemia can lead to neurological damage
  4. Failure to identify underlying cause: Recurrent episodes will continue without addressing the root cause
  5. Inappropriate glucagon use: Glucagon is only effective if liver glycogen stores are adequate

The treatment approach for non-diabetic hypoglycemia follows similar principles to diabetic hypoglycemia management but requires more thorough investigation of underlying causes since the condition is less common and often indicates a significant pathology.
