Researchers from Brigham and Women’s Hospital (BWH) think they’re on track to figure out just how to do that. They published their findings Monday in Nature Materials.
A quick primer on gastric bypass surgery. Though the specifics can vary, the surgery basically “shrinks” the size of a person’s stomach by blocking off a large portion of the organ from the rest. Surgeons do the same in the small intestine.
With a stomach that can now only hold a very small amount of food, patients can no longer eat large meals. Additionally, because the food they do eat no longer travels through the entire small intestine, the body doesn’t absorb as many nutrients. Cumulative effect: weight loss.
