A high glucose tolerance result with normal fasting blood glucose may indicate an abnormal glucose tolerance, and patients are advised to improve their symptoms through improved diet, exercise, or medication. Abnormal glucose tolerance generally refers to the glucose concentration of 7.8-11.1mmol/L after 2 hours of glucose tolerance test. 1. Diet: Patients need to eat a low sugar, low salt and low fat diet, avoiding foods with too much sugar, and abstaining from smoking and alcohol. Promote small meals, regular meals. Eat less refined sugar foods, such as condensed milk and candied fruit. 2. Exercise: People with abnormal glucose tolerance should strengthen exercise, which can speed up the consumption of glucose in the body, help control blood sugar and maintain a healthy weight range. 3. Drugs: Patients with abnormal glucose tolerance can also use voglibose, or other α-glucosidase inhibitors under the guidance of a doctor, which can more effectively lower the patient’s blood sugar. It is recommended that patients with abnormal glucose tolerance go to the hospital in time and follow the doctor’s instructions for treatment to avoid delays.
