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
- Recheck blood glucose after 15 minutes 2, 1
- If blood glucose remains <70 mg/dL, repeat treatment with 15-20g of carbohydrates 2, 1
- Continue monitoring and treatment until blood glucose is >70 mg/dL 1
- 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.
