What Is a Gastric Bypass (RNY)?
Gastric bypass roux en-Y (RNY) is a bariatric healthcare procedure that treats morbid obesity. Gastric bypass surgery helps reduce the stomach’s size by forming a small pouch in the stomach for storing food prior to digestion. The small size of the stomach pouch allows only a small quantity of food intake and sends a signal to the brain that the pouch/stomach is full when in reality only a part of the stomach is full. Thus, by reducing the functional volume of the stomach, gastric bypass surgery allows patients to reduce their weight gradually over time. Gastric bypass is an effective healthcare procedure that also helps reduce the risk of cardiovascular disease, diabetes mellitus type -2, hypertension, sleep apnea, gastroesophageal reflux disease, gall bladder disease, venous thromboembolic disease, and degenerative disc disease.
The Gastric Bypass (RNY) Procedure and Who Needs It
People with a high body mass index of 40+ and people with any of the co-morbid conditions are candidates for gastric bypass (RNY) surgery. Gastric bypass surgery is usually employed when all other weight loss methods have been exhausted (exercise, diet, medication, etc). The surgery is performed under general anesthesia during which an incision is made in the abdomen close to the stomach area. A small pouch is made in the upper part of the small intestines. This pouch is then joined with the middle part of the small intestines, bypassing the rest of the stomach. Food passes directly from the small pouch to the middle part of the small intestine via a “Roux limb.” The surgery typically requires 2-6 days stay in the hospital during which time the patient might be restricted to liquid foods, antibiotics, and pain medications. There are many complications associated with this surgery, and patients should consult their healthcare providers before option to undergo this type of operation.
