Patient's question:
I checked my uncle's blood sugar, and it was fasting blood sugar. The fasting blood sugar was 7.8. I don't know what the normal blood sugar level should be. Is a fasting blood sugar of 7.8 diabetes?Doctor's answer:
For the situation where your uncle measured a fasting blood glucose level of 7.8, it is recommended to measure post-meal blood glucose twice more. If both post-meal glucose readings are high, then diabetes should be considered. It is advised to undergo a glucose tolerance test and a hemoglobin A1c test for further confirmation if you are still unsure. If diagnosed with diabetes, it is recommended to undergo long-term oral hypoglycemic medication treatment or subcutaneous insulin injections, and to strictly follow a diabetic diet.
