The main way to diagnose diabetes is to check blood sugar. Key indicators of blood sugar: fasting blood sugar, blood sugar two hours after meal. If the patient has symptoms of diabetes, and the fasting blood glucose is higher than normal, reaching the diagnostic standard, more than or equal to 7.0mmol/L, or the blood glucose two hours after meal reaches 11.1mmol/L, it is considered that diabetes can be diagnosed. If the patient has no symptoms and only has an examination, he or she finds that his or her fasting blood sugar reaches more than 7.0mmol/L, or the blood sugar reaches more than 111mmol/L two hours after the meal, which cannot be regarded as a complete diagnosis. We need to go to the hospital for ogtt (glucose tolerance test) to determine whether there is diabetes.
