Bariatric surgery is more targeted at losing weight. Metabolic surgery is more indicated for surgery for the improvement of metabolic parameters, such as reducing the risk of hypertension, diabetes, heart attack and stroke. Differences is in the terminology. Type of surgery is the same.

The correct term we use now is Bariatric and Metabolic surgery. The 2 most common operations are laparoscopic sleeve gastrectomy and laparoscopic roux-en-y gastric bypass (also known as gastric bypass)

These surgeries are known to be most effective and long lasting for people with severe obesity, as they not just limit the food intake, but also make hormonal changes, alter the body set point and metabolism.
