Some patients with impaired glucose tolerance will recover as normal, while others will develop diabetes. 1. When it is clear that glucose tolerance is impaired, non-pharmacological treatments should be given in a timely manner according to the doctor’s instructions, including controlling the intake of sugar-containing substances and staple foods, eating more fresh vegetables, and giving appropriate activities every day. Some patients will recover as normal. 2. After impaired glucose tolerance, the condition of some patients will progressively worsen and eventually develop into diabetes. At this time, it is necessary to follow the doctor’s instructions to use hypoglycemic drugs to make blood glucose control standards, such as metformin, dagliflozin, griseofulvin, insulin and so on. After impaired glucose tolerance, you should go to the endocrinology department of a regular hospital and choose a reasonable treatment plan under the guidance of your doctor.
