Treatment of Hypoglycemia in Non-Diabetic Individuals

For conscious non-diabetic patients with hypoglycemia, administer 15-20g of glucose orally, recheck blood glucose after 15 minutes, and repeat treatment if blood glucose remains <70 mg/dL. 1

Initial Assessment and Treatment

Hypoglycemia Classification

  • Level 1 (Mild): Blood glucose <70 mg/dL but ≥54 mg/dL
  • Level 2 (Moderate): Blood glucose <54 mg/dL
  • Level 3 (Severe): Any blood glucose level with altered mental status requiring assistance 1

First-Line Treatment for Conscious Patients

  • Administer 15-20g of fast-acting carbohydrates 2, 1
  • Preferred options:
    • Glucose tablets (fastest absorption)
    • Fruit juice (4 oz)
    • Regular soda (4-6 oz)
    • Honey (1 tablespoon)
    • Sugar cubes or granulated sugar (1 tablespoon)
    • Jelly beans or other candy (check serving size for 15-20g carbohydrate content) 1

For Unconscious Patients or Those Unable to Swallow

  • Administer glucagon via subcutaneous, intramuscular, or intravenous injection 3
  • Dosage:
    • Adults and children >25kg or ≥6 years with unknown weight: 1 mg
    • Children <25kg or <6 years with unknown weight: 0.5 mg 3
  • Call for emergency assistance immediately after administering glucagon 3

Monitoring and Follow-up Care

Post-Initial Treatment

  1. Recheck blood glucose after 15 minutes 2, 1
  2. If blood glucose remains <70 mg/dL, repeat treatment with 15-20g of carbohydrates 2, 1
  3. Continue monitoring and treatment until blood glucose is >70 mg/dL 1
  4. Initial response should be seen within 10-20 minutes 1

Once Blood Glucose Normalizes

  • Provide a more substantial snack or meal containing complex carbohydrates and protein to maintain blood glucose levels 1
  • Complex carbohydrates with protein help prevent recurrence of hypoglycemia 1

Identifying and Addressing Underlying Causes

Common causes of hypoglycemia in non-diabetic individuals include:

  • Medications or toxins capable of decreasing blood glucose
  • Fasting hypoglycemic disorders
  • Postprandial hypoglycemic disorders 4
  • Alcohol consumption
  • Critical illness
  • Cortisol insufficiency including hypopituitarism
  • Insulinoma
  • Post-bariatric or gastric surgery
  • Pancreas transplantation
  • Glucagon deficiency 5
  • Genetic causes (rare)
  • Paraneoplastic and immune causes (rare) 5

Special Considerations

Elderly Patients and Children

  • These populations are particularly vulnerable due to reduced ability to recognize symptoms
  • May require closer monitoring and more conservative glucose targets 1

Patients with Comorbidities

  • Renal failure may contribute to hypoglycemia 1
  • Hepatic failure can lead to reduced hepatic gluconeogenesis 2

Alcohol-Induced Hypoglycemia

  • May require longer observation due to prolonged hypoglycemic effect 1

Disposition and Follow-up

Discharge Criteria

  • Clear cause identified
  • Good response to treatment
  • Adequate home support 1

Consider Admission for:

  • Recurrent hypoglycemia
  • Inadequate home support
  • Underlying serious illness 1

Complications of Untreated Hypoglycemia

Severe or prolonged hypoglycemia can lead to:

  • Neurocognitive impairment
  • Seizures
  • Loss of consciousness
  • Permanent brain damage
  • Depression
  • Death 2

Early hypoglycemia has been associated with:

  • Longer ICU length of stay
  • Greater hospital mortality, especially with recurrent episodes 2

By following this structured approach to hypoglycemia management in non-diabetic individuals, clinicians can effectively treat the immediate condition while investigating and addressing the underlying cause.
