Impaired glucose tolerance may return to normal with medication, but it may also progress to diabetes. Early intervention can delay the progression to diabetes, prevent and/or slow down the development of diabetes complications. Early intervention measures include: health education, medical nutritional therapy, exercise therapy, blood glucose monitoring, and medication. 1. Health education: including education for patients and their families, so that patients can fully recognize and master self-management skills, and their families can cooperate and assist patients in self-management. 2. Medical nutrition therapy: including reasonable control of total calories, balanced nutrition, restoration and maintenance of ideal weight. 3. Exercise therapy: the formulation of exercise plan should follow the principle of individualization, gradual progression and long-term persistence, and at least 150 minutes of moderate exercise per week is recommended. 4. Blood glucose monitoring: regular blood glucose monitoring should be carried out for early detection of diabetes and timely treatment. 5. Medication: Metformin is currently available to assist in improving the patient’s abnormal glucose tolerance status. However, please use it under the guidance of a doctor. For patients with impaired glucose tolerance, it is recommended to consult a doctor in time and standardize the treatment under the doctor’s guidance.
