The Gastric Bypass
(aka Roux-en-Y) is one of the most popular weight loss surgeries. In a Gastric Bypass, a small pouch is segmented off from the remaining stomach tissue, creating a new stomach roughly the size of a golf ball and no larger than a tennis ball. The middle section of the small intestines (known as the jejunum) is then rerouted to the newly created pouch, bypassing the stomach and duodenum (the first section of the small intestines).
Decreasing the size of the stomach and bypassing a portion of intestines not only reduces the amount of food that can be consumed and leaves you with a feeling of fullness (satiety), but also shortens the time it takes for food to pass through the body and limits the absorption of bad nutrients like saturated fats. This type of bypass operation has proven to be an effective, consistent way of losing weight and keeping it off.
Recovery time: 3-5 weeks
