Bariatric surgery is nothing but the common term collectively used for many types of weight-loss surgeries. These surgeries make changes to your digestive system to help you lose weight. They either limit the amount of food you can intake or reduce your ability to absorb nutrition and in some cases both.

Such types of surgeries are done when diet or exercise plans have not worked out for the person and when the person has some serious health condition as a result of their weight. Gastric bypass is the most common type of bariatric surgery and most surgeons prefer this surgery as it usually has fewer complications than other weight-loss surgeries do.

These surgeries generally pose major risks and side effects and the patient has to make changes to their diet permanently and also schedule a fixed exercise regime so that they can ensure the lasting success of bariatric surgeries.
