Patients usually return to normal activities within three to five weeks after gastric bypass surgery, explains WebMD. These weight loss surgeries are typically laparoscopic, but open surgeries may require longer recovery times.
The typical hospital stay following gastric bypass surgery is two to three days, according to WebMD. Few patients experience minor complications following the procedure, and fewer than 5 percent experience severe issues. Approximately one in two patients develops harmless gallstones after surgery, and 15 to 25 percent require gallbladder removal surgery at some point. Lifestyle changes, such as small, frequent meals, nutritious food choices and plenty of exercise, can help maintain a healthy body and keep the weight off following gastric bypass surgery.
