Staple line leaks occur in an average of 2.1 percent of patients as of July 2015, and bleeding occurs in 1.2 percent of patients, Bariatric Surgery Source reports. While 20 percent of patients experience GERD within the first year following surgery, this percentage drops to 3 percent three years after the procedure.

If food empties into the small intestine too rapidly, this can cause symptoms of dumping syndrome such as faintness, shakiness, nausea and diarrhea, states WebMD. Patients often have belly pain during the first week after the procedure, and the incision site may be sore. Irregular bowel movements are also common after surgery. Because the stomach cannot easily absorb certain vitamins and nutrients, individuals may struggle with poor nutrition over time. Some people develop an infection at the incision site, gallstones, anemia, osteoporosis or a blood clot in the lung. Continuous overeating may stretch the stomach, canceling out the weight-loss benefits of this procedure.
