A Roux-en-Y (say "roo-en-why") gastric bypass is surgery to help you lose weight. It does this in two ways. First, it makes the stomach smaller. Second, it changes the connection between the stomach and the intestines. These changes help you eat less and feel full sooner.
You will be asleep during the surgery. The doctor will make several small cuts in your belly. These cuts are called incisions. Then the doctor puts special tools and a camera through the incisions. Next, the doctor separates the upper part of your stomach from the rest of your stomach to make a small pouch. This new pouch will hold the food you eat. The doctor will connect the new stomach pouch to the middle part of your small intestine. Then he or she will close the incisions with stitches. The incisions leave scars that fade with time.
After the surgery, the food you eat will go from the small pouch to the middle part of your intestine. Food will no longer go through the lower part of your stomach or the first part 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 2 to 4 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 or nurse call line 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.
