Gastroesophageal reflux disease (GERD) is a significant public health problem affecting up to 40% of the adult population in the United States. Even though a direct cause-and-effect relationship between obesity and GERD has not been clearly established, obesity is often associated with GERD.
As many as 55% of morbidly obese patients presenting for gastric bypass surgery have symptoms of chronic GERD. Gastric bypass surgery is currently recommended as an attractive alternative to antireflux surgery for the primary treatment of GERD in morbidly obese patients. Recent evidence suggests that gastric bypass surgery is the most effective antireflux procedure in morbidly obese patients.
