I. Pay attention to lifestyle. To eat less high-calorie food, control the weight within the standard range (BMI < 24), overweight patients should lose weight. In terms of food composition, carbohydrates are the mainstay, less high-fat foods, and more coarse fiber foods can be appropriate. If the patient only relies on hypoglycemic drugs and does not pay attention to diet control, it is difficult to control blood sugar. type 2 diabetes patients have relatively insufficient insulin secretion, you can take a small amount of multi-meal diet principle, the amount of a meal even into two meals or more meals to eat, you can make the burden on the pancreas is reduced, and do not wait for hungry to eat again when eating meals. Second, to exercise reasonably. If diabetic patients try to participate in exercise, blood glucose levels will certainly drop from the original basis. It is recommended that diabetic patients exercise five days a week, about half an hour a day, if their physical condition permits. Because the exercise time is usually after meals, the amount of exercise directly affects the level of blood sugar after meals. If the patient's activity is increased than usual, the meal can be added or the medication can be reduced appropriately. However, diabetic patients should choose the appropriate exercise according to their own physical condition when exercising. Third, the influence of emotion on blood sugar is estimated to be rarely noticed. In fact, emotions have a great impact on blood sugar, so diabetic patients should try to be optimistic, take a positive attitude towards life, do not be too pessimistic about the disease, which in turn is to add insult to injury. Fourth, do not drink too much alcohol. Some patients drink a lot of alcohol will cause hypoglycemia due to alcohol damage to the liver, resulting in a decline in liver glycogen reserves, and some patients drink a lot of alcohol due to impaired sugar metabolism caused by hyperglycemia, drinking too much alcohol may also lead to alcoholic liver damage. Fifth, the stress state to strengthen blood sugar monitoring. When diabetic patients are in stressful conditions such as infection and fever, the secretion of various glucagon hormones will increase and blood sugar will rise. Therefore, diabetic patients must closely monitor blood glucose changes when their bodies are in the above-mentioned situations in order to adjust medication in a timely manner. Sixth, blood lipid and blood pressure monitoring go hand in hand. In a study done in Denmark, it was found that the incidence of small and large vessel comorbidities in diabetic patients with good blood glucose control, blood pressure and lipid compliance and anticoagulation therapy was much lower than in diabetic patients who were only treated conventionally. Therefore, it is recommended that diabetic patients should pay attention to blood glucose control and not forget to monitor blood lipids and blood pressure.
