Diabetic patients are prone to hypoglycemia may be caused by excessive medication dosage, dietary control, and delayed insulin secretion. 1. Excessive dose of medication: If diabetic patients use too large a dose of medication during treatment with hypoglycemic drugs, it will cause a drop in blood glucose, leading to hypoglycemic episodes. 2. Dietary control: diabetic patients need to do a good job of dietary management and control the total daily calorie intake, so it may lead to insufficient food intake, causing hypoglycemic episodes. 3. Delayed insulin secretion: The insulin secretion function of diabetic patients will be abnormal, when insulin secretion is delayed, the peak time of blood glucose after eating and the peak value of insulin can not be matched, which will lead to hypoglycemic episodes. Diabetic patients with recurrent hypoglycemic episodes can go to the hospital and ask the doctor to make a judgment and clarify the cause of the disease.
