Hyperglycemia occurs when the blood sugar level is higher than the prescribed level. It may take days or hours to form. You may have high blood sugar without knowing it. The fasting blood glucose concentration of normal people in the morning is 80 ~ 120 mg%. Fasting blood glucose concentration exceeding 130 mg% is called hyperglycemia. If the blood sugar concentration exceeds 160 ~ 180 mg%, some glucose will be excreted with urine, which is diabetes. Blood sugar concentration below 70 mg% is called hypoglycemia. Hyperglycemia is also one of the three highs. In addition, "two highs" are hypertension and hypertriglyceridemia. The total calories should be determined according to the patient's nutritional status, weight, age, gender and physical activity. The principle is to make the patient's weight slightly lower than or within the standard weight range. Under normal circumstances, the daily calorie intake is 1500- 1800 calories, and fat people should reduce it to 1200- 1500 calories. Among them, carbohydrates account for about 60% of the total calories, equivalent to 300-400 grams of staple food. Sugar in coarse grains decomposes slowly and is suitable for diabetics. Dietary fiber and vitamins should be sufficient: high-fiber foods can slow down the decomposition and absorption of carbohydrates and help balance blood sugar. Because eating less will lead to insufficient supply of vitamins and trace elements, it is advisable to eat more fresh vegetables. Fruit contains more fructose, so it is best to avoid eating it when blood sugar is not well controlled. It can be supplemented by oral multivitamin and mineral tablets (pills). Prevention and treatment of complications: Diabetes patients have disorder of fat metabolism, high blood lipid and rapid development of atherosclerosis. The cholesterol content in food must be controlled, generally not exceeding 300mg/ day, which is equivalent to one egg per day. Eat less or don't eat high cholesterol animal fat and animal offal food. Diabetic patients are also prone to renal insufficiency, so urine protein should be checked frequently. Fruit therapy for hyperglycemia [3] Patients with hyperglycemia eat fruits containing more fructose, which will make their blood sugar drop rapidly. Common fruits with hypoglycemic function are 1 and litchi. It is a delicious fruit in subtropical area, which is rich in nutrition and has many medicinal functions, such as promoting fluid production, lowering blood sugar, improving intelligence, strengthening spleen and beautifying. Litchi is sweet, slightly warm and slightly sour. For polydipsia, toothache and other symptoms are effective. 2. Bananas are particularly rich in nutrition, with high contents of protein, fat, phosphorus and potassium. Potassium is very important for maintaining acid-base balance and improving muscle function. Lack of potassium can make people feel weak.

Dietary precautions for hyperglycemia 1, the staple food is generally rice and noodles, but we prefer it. 2. The protein source of hyperglycemia patients is soybean and its bean products. On the one hand, the protein it contains is of good quality; On the other hand, it contains no cholesterol and has the function of lowering blood fat, so it can replace some animal foods, such as meat. 3. During the calorie control period, when you are still hungry, you can eat some vegetables with less sugar, boil them in water and add some seasonings. Vegetables are essential foods for diabetics because of their high dietary fiber, high water content, low thermal energy and strong satiety. 4.
