Bariatric surgery (gastric bypass or band) significantly improves glycemic control and promotes medication discontinuation in pre-diabetic and diabetic patients, with remission rates of 73.9% for diabetics and 83.5% for pre-diabetics within 24 months.

If you have pre-diabetes or diabetes and are struggling with weight, bariatric surgery (gastric bypass or band) is a highly effective intervention for achieving remission. This study shows that over 80% of pre-diabetics and nearly 74% of diabetics were 'cured' (normalized blood sugar) within two years, often allowing them to stop medications. This benefit applies across age groups and is not limited to the most obese patients, though access may vary by insurance type.
