Gastric bypass surgery is used to treat morbid obesity which is defined as having a Body Mass Index greater than 40. Gastric bypass is a weight loss surgery that involves both restrictive and malabsorptive technique to achieve weight loss.
The second basic component of gastric bypass surgery is the reconstruction of the GI tract which allows the newly partitioned stomach segments to drain properly. The method used in this reconstruction can differ in the lengths of small bowel used, the degree to which food absorption is affected, and the likelihood of adverse nutritional effects.
Roux-en-Y Gastric Bypass Surgery
Roux-en-Y Gastric Bypass is the most common form of gastric bypass being performed today. This procedure has been shown to be effective and safe over long term duration and thus it is widely accepted by both surgeons and insurance companies as the leading choice for weight loss surgery. The Roux-en-Y gastric bypass involves separating the stomach into a smaller, upper pouch and a larger, lower section, while the small intestine is divided and rerouted. The new small pouch is created at the top of the stomach where the food enters using staples to completely separate it from the lower portion of the stomach. The remaining larger, lower portion of the stomach is bypassed but not removed from the body as it is in something like the gastric sleeve surgery. Since the natural stomach outlet is located in the bypassed portion of the stomach it is also bypassed meaning a new connection is created to the intestines.
