When hypoglycemia occurs, hypoglycemia should be corrected quickly by eating desserts, cookies or candies containing simple sugars, or by drinking glucose and sucrose water directly. When severe hypoglycemia occurs, such as when a patient is in a coma, it is not recommended to correct hypoglycemia by eating to prevent aspiration, and high concentrations of glucose should be given immediately by intravenous push, with a recommendation of 40-60 ml of 50% glucose intravenously. Hypoglycemia is very harmful and the treatment when it occurs is far less important than prevention. Every diabetic patient usually always has candy and cookies, monitors blood sugar diligently, and adjusts diet and exercise according to the fluctuation of blood sugar. If in the case of repeated hypoglycemia, the dose of insulin or medication needs to be reduced as early as possible under the guidance of a diabetes specialist.
