Some studies have shown that patients with impaired glucose tolerance can delay or prevent the onset of diabetes through lifestyle interventions, including encouraging overweight or obese patients to lose weight. Therefore, when obese patients with impaired glucose tolerance lose weight, it is possible to delay or prevent the development of diabetes. Hypoglycemia is defined as a fasting blood glucose <7.0mmol/L, along with a 2-hour post glycemic load blood glucose between 7.8 and 11.1mmol/L. Such people may develop diabetes if risk factors are not actively controlled. However, if obese patients through strict dietary control and reasonable exercise and other lifestyle adjustments may improve the situation of impaired glucose tolerance, so that the blood glucose level back to the normal range, but not absolute, depending on the individual situation, if necessary, can be prescribed to take metformin, acarbose and other drugs treatment. It is recommended that obese patients with impaired glucose tolerance be treated under the guidance of a medical professional and have their blood glucose checked regularly.
