Community medical question

it depands upon patient history, duration of diabetes, control of diabetes (HBA1c) and status of kidneys

Agree with Dr Bm Rathore
It totally depends on diabetes control / weight etc
If you have any blood tests done recently get in touch also your blood sugar reading if you check at home

If your blood sugar is controlled with metformin means A1c is normal and having no problem you can continue. But keep record of your sugar levels.
