Can bariatric (weight loss) surgery be reversed?

Some types of bariatric surgery can be reversed. However, the reversal operations carry the same or greater risks than the original procedure. Reversal operations are rare. They may be considered when very serious and long-term complications occur after the first operation.

Lap-Band procedures are most easily reversed. Reversal of the gastric bypass procedure is rarely needed and is considered risky by most doctors.

The sleeve gastrectomy and duodenal switch cannot be reversed as a portion of the stomach is removed. However, these two surgeries can be changed into a different procedure.

If you decide to reverse your surgery, you will likely regain the weight that you lost from the original surgery.

Surgery for weight loss can be reversed, but reversal procedures are usually more dangerous than the original ones. We would only consider reversing these operations in patients who have significant long-term problems from the surgery. It is important to note that anyone who has the operation reversed will regain the weight they lost after the first surgery.
