Also known as ‘Roux-en-Y gastric bypass’ (RGYB) is counted among the “gold standard” for weight-loss surgery by the American Society for Metabolic and Bariatric Surgery and the National Institutes of Health.
It works by limiting food intake and by reducing the absorption of food. Intake of food is restricted by a small pouch similar in size to the adjustable gastric band. Also, absorption of food in the digestive tract is decreased by excluding most of the belly, upper intestine and duodenum from contact with food by routing it directly from the pouch into the small intestine.
The surgery is done using the laparoscopic method. It involves making six to seven incisions in the stomach through which a small device is connected to a video camera and surgical instruments are inserted. The surgeon staples the top part of the abdomen so it can be separated from the bottom for creating a small belly pouch. This small pouch limits food intake. A portion of the small intestine known as the jejunum is attached to the small stomach pouch allowing food to bypass the duodenum, the lower stomach. This bypass helps in decreasing the amount of nutrients and calories the body absorbs, called malabsorption.

You need to know that specifics of the gastric bypass usually depend on an individual patient and the surgeon’s practices. Previously surgery was performed making a large incision. However, these days it is done using the laparoscopic method that involves inserting surgical instruments through several tiny incisions in the belly.
Once incisions are made, the surgeon would across the top of your tummy, sealing it off from the rest of your abdomen. The final resulting pouch is similar to the size of the walnut. It can hold only an ounce of food. Usually, your abdomen can hold nearly 3 pints of food. Next, the surgeon cuts the small intestine and sews part of it directly onto the pouch. The food you eat directly goes into this small pouch of the tummy and directly into the small intestine sewn to it. Food bypasses most of your belly and the first section of the small intestine, and instead enters directly into the middle section of the small intestine. The entire duration of surgery lasts for four to five hours.
