After surgery, most of the stomach is separated from a small "pouch" about the size of an egg (30 cc) that limits your food in-take. The disconnected stomach stays in place and produces acids that meet up with food further downstream in the small intestine. The closing off of a majority of the stomach also changes the amount of hunger hormone produced, eliminating hunger for most patients, and allowing patients to eat smaller amounts of food and not experience extreme hunger.
The small intestine is rerouted slightly so that fewer calories and nutrients are absorbed by the body. Because a portion of the small intestine is bypassed, you must take vitamins and supplements after gastric bypass surgery and be checked post-operative to prevent nutritional deficiencies. Because of the re-routing of a portion of the stomach and intestine with gastric bypass surgery, greater weight loss and type 2 diabetes resolution are expected compared to gastric band procedures.
Our surgeons can perform the bypass surgery using minimally-invasive techniques. The surgeon can use a laparoscope, a small camera that is inserted into your belly, and thin surgical instruments. For patients, this means less blood loss, smaller scars, and a shorter recovery time. Our surgeons are highly-experienced in laparoscopic surgery techniques.
