Reversal of abnormal glucose tolerance can be as good as normal. In the pre-diabetic stage, abnormal glucose tolerance is caused by impaired pancreatic islet function due to poor lifestyle. It is possible to reverse it through lifestyle intervention, such as regular meal timing, eating less carbohydrate or starch-rich food, and supplementing with high-quality proteins, vitamins, and dietary fiber-rich food appropriately, etc., and can be restored to the same state as normal people after the reversal. If abnormal glucose tolerance is not taken seriously, it is likely to develop into diabetes. Therefore, once abnormal glucose tolerance is detected, it is recommended to cooperate with professional doctors as soon as possible to improve the examination, to clarify the severity, to start from adjusting the lifestyle, to strictly control the weight, to reduce the weight appropriately, and to strengthen the daily movement and exercise, so as not to aggravate the damage. For patients with abnormal glucose tolerance, it is recommended to go to the endocrinology department of regular hospitals, and choose a reasonable treatment plan under the guidance of doctors.
