High fasting blood glucose should be controlled by diet, increased exercise and timely medical evaluation of whether to take medication to control. 1. Dietary control: The normal fasting blood glucose range for adults is 3.9-6.1mmol/L. If fasting blood glucose is high, dietary control should be implemented to avoid consuming too much high-fat and high-sugar foods, such as lychee, cinnamon, cream cake, etc. Foods with a low glycemic index, such as cucumbers, tomatoes, green leafy vegetables, etc., should also be consumed. 2. Increase exercise: People with high fasting blood sugar should also increase exercise, such as walking after meals, etc. Exercise and weight loss can help improve the body’s sensitivity to insulin and help reduce fasting blood sugar. 3. Timely medical evaluation: For people with fasting blood glucose higher than 7.0mmol/L and typical diabetic symptoms, the diagnostic standard of diabetes has been reached, and they should consult a doctor in time, and the professional doctor will carry out the typing and make individualized drug program to control blood glucose, such as oral hypoglycemic drugs, and also use insulin to control blood glucose under the guidance of the doctor. When high fasting blood glucose is found, in addition to controlling the intake of carbohydrates and sugar and increasing exercise, one should seek timely medical treatment and be evaluated by a professional doctor to formulate an individualized glucose-lowering plan to avoid delaying the condition.
