Bariatric revision surgery is a procedure that corrects or modifies a previous weight loss surgery when it's no longer effective or has caused complications. It can be performed to address insufficient weight loss, weight regain, or complications like ulcers or strictures.

​

Revisional bariatric surgery procedures occur in about 7% to 15% of bariatric surgery patients. To determine whether a revisional bariatric surgery is needed, doctors will assess a patient’s overall health, weight loss progress, and any quality-of-life issues.

​

There are three categories of revisional bariatric surgery: correction or modification, alteration, and reversal. The follow-up procedure may improve the effectiveness of the original surgery and a patient’s quality of life (if the initial surgery caused unwanted side effects).
