Testing a diabetes medication to improve blood vessel health after gestational diabetes

This research study is testing whether metformin—a common diabetes medication—can help improve how blood vessels work in women who experienced gestational diabetes during pregnancy. Women with a history of gestational diabetes have a higher risk of heart disease later in life, even after their blood sugar returns to normal. Researchers want to understand why this happens and whether the medication can prevent or reduce this risk.

Women who had gestational diabetes face double the risk of developing heart disease in the years after pregnancy, but doctors don't fully understand why their blood vessels remain damaged even after their diabetes goes away. This study aims to find out what's causing the problem and whether this medication could help prevent serious heart disease before it starts.
