Why is metformin given to pre-diabetic patients? Answering this Quora query, Dr Pranav Ghody, a consultant endocrinologist and diabetologist at Wockhardt Hospitals, Mumbai Central, explained that pre-diabetes indicates that blood sugar levels are higher than normal but not high enough to be classified as diabetes. “At this stage, the body shows signs of insulin resistance . Metformin helps the body use insulin more effectively and reduces liver production of extra glucose. In people at higher risk, such as those who are overweight, have a strong family history, or rising HbA1c, it can slow or even prevent the progression to type 2 diabetes when paired with lifestyle changes,” said Dr Ghody.
