Hello! The diagnostic criteria of diabetes are based on blood sugar. At present, China stipulates that the normal fasting venous blood glucose is less than 6.1mmol/L. The WHO diagnostic criteria are: l Fasting venous blood glucose ≥ 7.0 mmol/l, and fasting is defined as no calorie intake for at least 8 hours. Or blood sugar ≥11.1mmol/l 2 hours after lOGTT (oral glucose tolerance test) load. The method defined by WHO should be adopted, which is equivalent to 75g of anhydrous glucose dissolved in water. Or l For those with typical hyperglycemia symptoms or hyperglycemia crisis, the random blood glucose is ≥11.1mmol/L, and your fasting blood glucose is 14. It needs to be checked again to ensure that if there are no symptoms of hyperglycemia, a glucose tolerance test can be conducted if necessary. Treatment: Your calorie intake depends on your age, body shape, nature of work, eating habits and so on. Please go to a specialist, and doctors, nurses and nutritionists will give you the best treatment plan according to your situation. Nutritional balance is more important. Staple food and non-staple food, vegetarian food, coarse grains, noodles and rice are all suitable. The patients we face are the most difficult oily foods to control, such as edible oil, peanuts, melon seeds and other nuts, fried foods and so on. According to the recommendations of "Guidelines for the Prevention and Treatment of Type 2 Diabetes in China" in 2007, newly diagnosed obese patients and overweight patients were treated with metformin hydrochloride as the initial treatment.
