Hypoglycemia: Prevention and Treatment
DEFINITION
- Blood glucose level ≤ 70 mg/dL (3.9 mmol/L)
- Clinically, hypoglycemia is suggested by typical symptoms (tremulousness, diaphoresis, tachycardia or mental status change) that is corrected by carbohydrate intake.
- Most often, hypoglycemia is caused by too much insulin or oral hypoglycemic agent, or not enough food intake.
