The first point is not to eat too much, that is, to control the calorie intake, in fact, for a wide variety of food, a variety of diets can be eaten, only to add up the total calorie sum of various foods, so as to ensure that the calorie intake does not exceed the standard, in order to allow patients to control blood sugar smoothly. If the calorie intake exceeds the limit, it will affect the blood sugar. The second point is to follow the doctor’s instructions and choose the right hypoglycemic drugs. There are many types of hypoglycemic drugs, so we should choose the right hypoglycemic drugs according to the patient’s specific condition and blood glucose situation, in order to help the patient’s blood glucose to be controlled smoothly. The third point, for the food not suitable for diabetic patients, must not eat, such as fried or relatively high calorie food.
