How to treat hypoglycemia (low blood sugar) with a glucose level of 33 mg/dL?

Treatment of Hypoglycemia with Glucose of 33 mg/dL

For severe hypoglycemia with a glucose level of 33 mg/dL, immediately administer 15-20g of oral glucose if the patient is conscious, or use glucagon injection if the patient is unconscious or unable to safely consume oral carbohydrates. 1, 2

Immediate Treatment for Conscious Patient

• Administer 15-20g of pure glucose orally (glucose tablets or solution preferred as they provide the most effective treatment) 1, 3
• Any carbohydrate-containing food with glucose can be used if glucose tablets are not available 1, 3
• Recheck blood glucose after 15 minutes; if hypoglycemia persists, repeat the treatment with another 15-20g of carbohydrate 1, 2
• Blood glucose should be evaluated again 60 minutes after initial treatment, as additional treatment may be necessary 3, 1
• Once blood glucose returns to normal (>70 mg/dL), the patient should consume a meal or snack to prevent recurrence 1, 2

Treatment for Unconscious Patient or Unable to Take Oral Carbohydrates

• Administer glucagon via subcutaneous, intramuscular, or intravenous injection 4
• For adults and pediatric patients weighing more than 25 kg or for pediatric patients with unknown weight 6 years and older: administer 1 mg (1 mL) of glucagon 4
• For pediatric patients weighing less than 25 kg or for pediatric patients with unknown weight less than 6 years of age: administer 0.5 mg (0.5 mL) of glucagon 4
• If there has been no response after 15 minutes, an additional dose may be administered using a new kit while waiting for emergency assistance 4
• Call for emergency assistance immediately after administering glucagon 4

Follow-up Care

• When the patient has responded to treatment and is able to swallow, give oral carbohydrates to restore liver glycogen and prevent recurrence of hypoglycemia 4, 2
• Any episode of severe hypoglycemia or recurrent episodes of mild to moderate hypoglycemia require reevaluation of the diabetes management plan 3, 2
• For patients with hypoglycemia unawareness or recurrent severe episodes, raise glycemic targets for at least several weeks to reverse hypoglycemia unawareness and reduce risk of future episodes 2, 5

Prevention of Future Episodes

• Identify patients at higher risk for hypoglycemia, including those on insulin or sulfonylurea therapy 3, 2
• Coordinate medication administration with meal timing to minimize risk 3, 2
• Educate patients about situations that increase hypoglycemia risk, such as fasting, delayed meals, exercise, sleep, and alcohol consumption 2
• For patients with recurrent hypoglycemia, a 2-3 week period of scrupulous avoidance of hypoglycemia is advisable to restore awareness 5
• Consider continuous glucose monitoring for patients with increased risk for hypoglycemia, impaired awareness, frequent nocturnal hypoglycemia, or history of severe hypoglycemia 3, 6

Common Pitfalls to Avoid

• Delaying treatment of hypoglycemia, which can lead to severe outcomes 2
• Failing to document blood glucose before treatment 2
• Not adjusting insulin doses after hypoglycemic episodes 2
• Using protein to treat hypoglycemia, as it may increase insulin secretion 1
• Adding fat to carbohydrate treatment may slow and prolong the acute glycemic response 1

Remember that a glucose level of 33 mg/dL represents severe hypoglycemia requiring immediate intervention to prevent serious neurological consequences and potential mortality 5, 7.
