Roux-en-Y Surgery - Frequently Asked Questions

The Roux-en-Y gastric bypass procedure is a type of weight loss surgery in which the size of the stomach is reduced along with the ability of the intestines to absorb calories. This surgical procedure is very effective for morbidly obese patients, although it's not for everyone. If you're considering gastric bypass procedures, be sure that you know all the facts before making your decision. Here are the answers to the most frequently asked questions about Roux-en-Y surgery.

How does the procedure work?

During Roux-en-Y surgery, the bariatric surgeon will first staple the stomach to create a small pouch, which will be your new stomach. This pouch is then connected to the small intestine, bypassing the bottom portion of the stomach and the top of the small intestine. Following Roux-en-Y surgery, you will feel full when eating smaller portions of food, and the small intestines will absorb fewer calories.

What can I expect after Roux-en-Y surgery?

Most patients remain in the hospital for three to six days following this weight loss procedure, returning to work within 10 to 14 days. Most patients are fully healed within six weeks. Over time, most patients experience a loss of 65 percent to 80 percent of their total excess weight, depending on their original weight and their commitment to the necessary lifestyle changes.

What lifestyle changes are necessary?

Following Roux-en-Y surgery, you will need to be committed to making substantial lifestyle changes. After surgery, you will be able to eat only about 1/4 cup of food at a time. A year after the surgery, most patients can eat about one cup of food at a sitting. Foods that you enjoy now may cause discomfort or nausea, especially if you currently eat a diet high in sugars or fats. Roux-en-Y patients must take dietary supplements to replace the vitamins and minerals that are no longer absorbed by the small intestines. Your surgeon may refer you to a dietician that will help you come up with a personal diet plan.
