Glucose tolerance is the abbreviation of glucose tolerance test. If the one-hour blood glucose concentration of glucose tolerance test is high, it may be the manifestation of impaired pancreatic islet function, which requires proper exercise and diet control, and if necessary, medication. 1. Appropriate exercise: If the one-hour glucose concentration of glucose tolerance test is high, you can do some sports to promote the metabolism of glucose in the tissues. 2. Dietary control: It is also necessary to actively control the diet and limit the intake of glucose to reduce the burden on the pancreatic islets. 3. Take medication: If the one-hour blood glucose concentration in glucose tolerance test is persistently high, you can also take oral hypoglycemic drugs such as metformin and glimepiride as prescribed by the doctor to actively treat the problem and keep the blood glucose concentration stable. If the one-hour blood glucose concentration is high during the glucose tolerance test, it is best to consult a doctor in time for C-peptide, glycated hemoglobin and other related tests, and you need to actively treat and change your daily dietary habits under the guidance of your doctor in order to maintain your health.
