A sharp increase in blood glucose after a meal, or low blood glucose before a meal, leading to subsequent blood glucose rebound, are the main causes of blood glucose fluctuations. To avoid blood sugar fluctuations, it is necessary to ensure the stability of blood sugar before meals and 2 hours after meals. The specific method is three moves in parallel: diet, exercise and medication in parallel. 1. Diet: Determine the diet plan according to the height, weight and activity under the guidance of the doctor, and set the quantity at regular intervals. In the selection of food types, it is advisable to choose foods with weak glycemic capacity, such as low-fat foods; mix coarse and fine staple foods, and eat less fine grains; eat mainly non-fermented noodles and semi-fermented noodles, and eat less porridge; eat more vegetables (especially green vegetables), but not root vegetables such as potatoes. If there is hyperglycemia after meal or hypoglycemia before the next meal, the meal can be divided under the guidance of the doctor, for example, if there is hyperglycemia after breakfast and hypoglycemia before Chinese meal, one third of the breakfast can be eaten around 10:00 am. 2.Exercise: It is recommended that sugar lovers arrange exercise in half an hour after meals, and medium-intensity exercise items are appropriate, such as brisk walking, tai chi, cycling, table tennis or badminton. It is not advisable to exercise on an empty stomach and pay attention to prevent the risk of exercise-induced hypoglycemia. It is better to monitor blood sugar after exercise, if blood sugar is <5.0mmol/
L, you can eat a little soda crackers, fruits, etc. 3. Medications: Under the guidance of the doctor in charge, you can choose medications to reduce fasting blood glucose fluctuations, such as long-acting insulin (such as glargine insulin) and medications to reduce postprandial blood glucose fluctuations (oral medications include acarbose, voglibose, repaglinide, nateglinide, glipizide, selegiline, ligliptin, saxagliptin, etc.; injectable medications include menthol insulin, menthol insulin 30, menthol insulin 50, menthol insulin 50, menthol insulin 50, etc.). The injectable drugs include menadione, menadione 30, menadione 50, arginine zinc recombinant lysergic insulin 25R, arginine zinc recombinant lysergic insulin 50R, exenatide. Among them, acarbose and voglibose can both reduce postprandial hyperglycemia and avoid hypoglycemia before the next meal. The use of insulin pumps also helps to reduce blood sugar fluctuations. Finally, setting an appropriate sugar control goal for yourself is more likely to keep your blood sugar stable: (1) Patients with type 2 diabetes who are under 60 years old and have no obvious complications are recommended to control their fasting blood sugar at 4.4 to 7.0 mmol/ L and non-fasting blood sugar at 4.4 to 10.0 mmol/L. (2) Patients with type 2 diabetes who are over 60 years old or have a history of severe hypoglycemia, or have obvious complications Or sugar patients diagnosed with type 1 diabetes, the above target range can be appropriately relaxed under the guidance of doctors.
