The miracle weight loss that comes as a result of bariatric surgery has been found to wear off after a number of years, but there is a procedure that helps patients keep the weight off for longer, NPR’s Shots blog reports. The stomach stretches over time, and despite bariatric surgery reducing the size of the stomach, over time it stretches out and allows the patient to consume more food before feeling full. About one in three patients experience significant weight gain a few years after the surgery. A procedure called Transoral Outlet Reduction puts in new sutures to reduce the size of the stomach once again. The minimally invasive surgery allows the patient to return to work the next day, and research conducted over the course of a decade suggest that it is effective with minimal side effects.
