Gastric Bypass surgery is known as the gold standard with regard to Bariatric Surgery. It is the one surgery that hasn’t changed all that much, due to the results that it provides. Known as the Roux-en-Y gastric bypass, the procedure not only restricts the size of the stomach, but also re-routes the small intestines, for malabsorptive effects.
Your surgeon will create a smaller stomach pouch, and will attach a section of the small intestine to the pouch, bypassing the rest of the small intestine which is responsible for absorbing calories and nutrients. Because your stomach will be smaller, you will feel the sensation of being “full” sooner than you are used to, which means you will be consuming less food. Since a large portion of the small intestine is bypassed, you will also be absorbing fewer calories and food will be reaching the large intestine and colon quicker, thus leading to weight loss.
The pouch is created using staples, and the procedure is usually done laparoscopically to help the patient with scarring and the healing process. Patients usually notice weight loss after the first week or so, and will continue seeing steady results for up to 12 months as long as their lifestyle remains healthy and active. Studies have shown that a large percent of patients lose approximately one third of their excess weight in 1-4 years.
