Impaired glucose tolerance can be recovered through lifestyle intervention and medication. 1. Lifestyle intervention: patients with impaired glucose tolerance should carry out lifestyle intervention in time, such as reasonably controlling the total energy intake, limiting the intake of high-sugar food, increasing protein intake, eating more food rich in dietary fiber, appropriate exercise, weight reduction, etc. Most patients can delay the development of impaired glucose tolerance to diabetes, or even recover from impaired glucose tolerance after active lifestyle intervention. 2. Drug treatment: those who have not recovered from impaired glucose tolerance after active lifestyle intervention can be treated with hypoglycemic drugs such as metformin, acarbose, rosiglitazone, etc. Injectable insulin can also be applied under the guidance of the doctor for controlling blood sugar. Patients with impaired glucose tolerance should go to the hospital in time and receive standardized treatment under the guidance of the doctor to avoid further development of the condition.
