Diabetic patients with high postprandial blood glucose can be treated by controlling diet, increasing exercise or adjusting hypoglycemic drugs. 1. Diet control: When diabetic patients have high postprandial blood glucose, they should calculate the total calorie intake of food and reduce the intake of foods high in sugar, fat and salt, such as cakes, fatty meats and preserved foods. 2. Increase exercise: Studies have shown that increasing exercise appropriately can improve insulin resistance and help diabetic patients control their blood sugar. 3. Adjustment of hypoglycemic drugs: high postprandial blood glucose in diabetic patients may be caused by inappropriate hypoglycemic programs, and professional doctors can be consulted to adjust the type or dosage of hypoglycemic drugs. It is recommended that patients go to the Department of Endocrinology of regular hospitals for detailed consultation.
