A Roux-en-Y (say "roo-en-why") gastric bypass is surgery to make the stomach smaller. It also changes the connection between the stomach and the intestines. It can help you lose weight. The surgery limits the amount of food the stomach can hold. This helps you eat less and feel full sooner. Open surgery means that the surgery is done through a long cut (incision) in the belly.
You will be asleep during the surgery. The doctor will separate the upper part of your stomach from the rest of your stomach. This forms a small pouch. The pouch will hold the food you eat. The doctor will connect the new stomach pouch to the middle section of the small intestine. This part of the intestine is called the jejunum. After the surgery, the food you eat will pass from the small pouch into your jejunum. Food will no longer go through the lower portion of your stomach or the first section of your intestines.
You will stay in the hospital 1 or more days after the surgery. Most people can go back to work or their usual routine in about 4 to 6 weeks.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.
