Hypoglycemia Management

Diagnosis and Assessment

  • Hypoglycemia is defined as a blood glucose level <70 mg/dL, requiring prompt treatment 1, 2
  • Severe hypoglycemia is characterized by altered mental status requiring assistance 3

Treatment of Hypoglycemia

  • Administer 15-20g of oral glucose for conscious patients with hypoglycemia, with glucose tablets being the preferred option if available, and alternative options including juice, sugar cubes, or other fast-acting carbohydrates, as recommended by the American Diabetes Association and the American Heart Association 4, 2, 5, 6, 3, 7, 8, 9, 10
  • Recheck blood glucose after 15 minutes; repeat treatment if hypoglycemia persists, as suggested by the American Diabetes Association 11, 7, 8, 12
  • The following treatment guidelines apply:

    Level Glucose Level Treatment
    1 <70 mg/dL but ≥54 mg/dL 15-20g oral glucose [2, 5, 6, 3, 7, 8, 9]
    2 <54 mg/dL 20-30g oral glucose or glucagon [2, 5, 6, 3, 7, 8, 9]
    3 Severe event requiring assistance Glucagon or IV glucose [2, 5, 6, 3, 7, 8, 9]

Treatment of Severe Hypoglycemia

  • Administer glucagon via injection or intranasal route if available for patients with severe hypoglycemia, as recommended by the American Diabetes Association 3
  • Activate emergency services for seizures related to glucose abnormalities in situations such as first-time seizure, seizure lasting >5 minutes, or patient does not return to baseline within 5-10 minutes, as advised by the American Heart Association 13

Post-Treatment Care

  • Once blood glucose normalizes, provide a meal or snack containing protein and complex carbohydrates to prevent recurrence, as recommended by the American Diabetes Association 4, 11
  • Ensure adequate protein intake, approximately 0.8g/kg/day, to address potential protein deficiency, as suggested by the American Association for the Study of Liver Diseases 14
  • Provide 150-200g of carbohydrates daily to help manage blood glucose levels, as recommended by the American Diabetes Association 15
  • Target a rate of sodium correction of 4-8 mEq/L per day, not exceeding 10-12 mEq/L in 24 hours, to avoid osmotic demyelination syndrome, as recommended by the American Association for the Study of Liver Diseases 14

Medication Management

  • Review medication history for insulin or sulfonylureas that may contribute to hypoglycemia, as recommended by the American Diabetes Association 16
  • Adjust or temporarily discontinue medications that may contribute to hypoglycemia or hyponatremia, such as insulin or diuretics, as suggested by the American Diabetes Association 16 and the American Association for the Study of Liver Diseases 14

Prevention and Education

  • Prescribe a glucagon emergency kit for patients at risk of severe hypoglycemia, as recommended by the American Diabetes Association 11
  • Train caregivers on recognition and management of hypoglycemia, as suggested by the American Diabetes Association 17, 12
  • Schedule outpatient follow-up within 1 week of discharge to monitor electrolytes and reassess clinical status, as recommended by the American Diabetes Association 18
  • Documenting frequency, severity, timing, and precipitating factors of hypoglycemic episodes is essential for diagnosis and treatment, as emphasized by the American Diabetes Association 8
  • Regular glucose monitoring, ensuring adequate carbohydrate intake with meals, adjusting medication if applicable, and educating caregivers about recognition and management are key prevention strategies, as emphasized by the American Diabetes Association 19

Institutional Policies

  • Institutions should implement policies requiring staff to notify physicians of abnormal blood glucose results, ensuring timely intervention and care, as recommended by the American Diabetes Association 17
  • Having immediate access to glucose tablets or other glucose-containing foods is crucial for prompt treatment of hypoglycemia, according to the American Diabetes Association 17
  • The American Diabetes Association recommends training staff in recognition, treatment, and appropriate referral for hypoglycemia, as well as training staff to administer glucagon, with the goal of improving patient outcomes 17
