Is fasting blood sugar 7.7 diabetes?

Fasting blood glucose 7.7mmol/L does not necessarily mean diabetes, but it is highly suggestive of diabetes.

The diagnosis of diabetes cannot be determined by a single fasting blood glucose value. Common diagnostic criteria include typical diabetes symptoms, such as polydipsia, polyuria, weight loss, etc., plus random blood glucose ≥11.1mmol/L or 2 hours postprandial blood glucose ≥ 11.1mmol/L. Although fasting blood glucose 7.7mmol/L exceeds the normal range, further tests are needed, such as oral glucose tolerance test, to confirm whether diabetes diagnosis criteria are met.

For fasting blood glucose 7.7mmol/L, it is recommended to seek medical advice promptly. Doctors generally ask for detailed medical history, conduct physical examination, and arrange further blood glucose testing items. If diabetes is highly suspected after comprehensive evaluation, lifestyle interventions may be initiated, including diet control, increased exercise, weight loss, etc.
