Gastric bypass is a surgical method that is able to help some obese individuals lose excess pounds and continue to maintain a healthy weight. The surgery has a major impact on your body and the digestive system since it actually removes parts of the stomach. If the patient is not willing to follow a strict diet in the weeks following surgery, there are serious risks of health problems.
