Postprandial blood sugar is too high: First, strict control of diet, because the relationship between diet and postprandial blood sugar is very close, if more carbohydrates are eaten, it will lead to higher postprandial blood sugar. Second, strengthen the exercise, especially pay attention to the exercise time should be arranged in 30-40 minutes after the meal after the rise in blood glucose, so that the effect of postprandial blood glucose is good. Third, patients need to make adjustments to the glucose-lowering treatment program, or take drugs to reduce postprandial blood glucose, such as sulfonylurea drugs or glycosidase inhibitors, DDP-4 enzyme inhibitors, SGL-T1 inhibitors, choose one or a combination of different mechanisms of drugs, to reduce postprandial hyperglycemia have a relatively good effect. Fourth, if the control of blood glucose is still unsatisfactory after oral hypoglycemic treatment, you can use GLP-1 analog injection or insulin, such as short-acting insulin or pre-mixed insulin subcutaneous injection before meals, can also be very good control of postprandial blood glucose.
