Hypoglycemia Treatment Guidelines

Immediate Treatment for Conscious Patients

The American Diabetes Association recommends administering 15-20 grams of oral glucose immediately to conscious patients with hypoglycemia (blood glucose <70 mg/dL), and rechecking blood glucose after 15 minutes, repeating treatment if hypoglycemia persists 1, 2
Pure glucose tablets or glucose solution are preferred over other carbohydrate sources because the glycemic response correlates better with glucose content than total carbohydrate content 2
Any carbohydrate-containing food with glucose may be used if glucose tablets are unavailable, though orange juice and glucose gel are less effective at quickly alleviating symptoms 4, 2
Recheck blood glucose 15 minutes after carbohydrate ingestion, and repeat treatment with another 15-20 grams of carbohydrate if blood glucose remains <70 mg/dL 3, 1, 2
Evaluate blood glucose again 60 minutes after initial treatment to ensure sustained recovery 2

For patients on α-Glucosidase Inhibitors, use monosaccharides such as glucose tablets specifically, as these medications prevent digestion of polysaccharides (complex carbohydrates) 6, 4
A lower dose of 5-10 grams of carbohydrates may be appropriate for patients using automated insulin delivery systems, unless hypoglycemia occurs with exercise or after significant insulin overestimation 2
Avoid protein for treating hypoglycemia as it may increase insulin secretion and worsen the situation 2
Avoid adding fat to carbohydrate treatment as it slows and prolongs the acute glycemic response, delaying recovery 2

Glucagon should be prescribed for all individuals at increased risk of level 2 (glucose <54 mg/dL) or level 3 (severe event requiring assistance) hypoglycemia, and administered immediately when the patient is unconscious, having seizures, or unable/unwilling to consume oral carbohydrates 1, 2
Glucagon administration is not limited to healthcare professionals—caregivers, family members, and school personnel should know where it is and how to administer it 1

For severe hypoglycemia with altered mental status, administer 10-20 grams of intravenous 50% dextrose immediately, and recheck blood glucose every 15 minutes until levels exceed 70 mg/dL 5
Stop any insulin infusion immediately if present, and avoid overcorrection causing iatrogenic hyperglycemia 5

Level 1: Glucose <70 mg/dL but ≥54 mg/dL—treat with oral glucose 1
Level 2: Glucose <54 mg/dL—more urgent, requires immediate treatment 1
Level 3: Severe event with altered mental/physical status requiring assistance—requires glucagon or IV dextrose 1

Review occurrence and risk for hypoglycemia at every clinical encounter, and trigger immediate hypoglycemia avoidance education and reevaluation of the medical regimen for patients with hypoglycemia unawareness or one or more episodes of level 3 hypoglycemia 1
Patients with hypoglycemia unawareness should raise their glycemic targets to strictly avoid hypoglycemia for at least several weeks to partially reverse unawareness and reduce future risk 1
Ensure all at-risk patients carry glucose tablets or glucose-containing foods at all times, and educate them on the importance of consuming carbohydrates during and after exercise, and with alcohol consumption 2, 6
