Doctor's answer:

Based on your description, consider the possibility of diabetes. The diagnostic criteria for diabetes are fasting blood glucose > 7.0 mmol/L or postprandial blood glucose > 11.1 mmol/L after 2 hours. Combined with your auxiliary tests, the results during the physical examination met the diagnostic criteria for diabetes. However, the results from 26-30 showed impaired glucose tolerance and fasting glucose impairment, which is an intermediate state between normal and diabetes. Although these individuals are not currently diabetic, their risk of developing type 2 diabetes in the future is very high. The hemoglobin A1c test can typically reflect a patient's blood glucose control over the past 8 to 12 weeks.
Advice: It is recommended to regulate your diet, increase physical activity, avoid sweet foods, and avoid overeating. Eat more vegetables and have regular follow-up check-ups.
