Normal individuals do not experience elevated blood glucose after oral glucose administration because the amount of insulin secretion and insulin sensitivity are normal. Hypoglycemic tolerance (IGT) and impaired fasting glucose regulation (IFG) are a manifestation of impaired glucose regulation in pre-diabetes, representing an intermediate metabolic state between normal glucose homeostasis and diabetic hyperglycemia, indicating impaired glucose regulation, which is now commonly regarded as pre-diabetes. Li Fucheng, Department of Endocrinology, The First Affiliated Hospital of Henan College of Traditional Chinese Medicine Hypoglycemia (IGT): 7.8-11.1 mmol/L intravenous glucose 2 hours after oral glucose tolerance test (OGTT) Impaired fasting glucose regulation (IFG): 6.1-6.9 mmol/L fasting intravenous glucose Hypoglycemia and Impaired fasting glucose regulation has 3 possibilities of regression: 1. 2, Without scientific, effective intervention of diet plus exercise, most people will turn to type 2 diabetes. 3.If effective intervention with scientific, diet and exercise is done, some people can return to normal without turning to diabetes. The prevalence of impaired glucose tolerance in China is about 4.8%, and related studies have reported that the incidence of diabetes in people with impaired glucose tolerance decreased by 58% after 3 years of lifestyle intervention, while blood pressure and weight also decreased significantly compared to 68% in people without any intervention. Impaired glucose tolerance is only one step away from diabetes, and without intervention, diabetes will almost inevitably develop. This group of patients should take reasonable interventions under the guidance of their doctors to change their existing lifestyle habits, including diet control, increased physical activity, weight loss, etc., so that as many people as possible do not become diabetic.
