Gastric bypass success rate

Gastric bypass success rate is very high as long as the procedure is performed by a board certified or another well-qualified weight loss surgeon. At the same time, the long-term success will depend on the patient’s commitment to maintain a balanced diet and a healthy lifestyle. 

Most patients will be able to achieve excess weight loss of about 60 to 80 percent, and maintain at least 50 percent excess weight loss in the long run. If the patient maintains or exceeds these averages, their gastric bypass surgery is considered to be in medical terms a success.
