Roux-en-Y Gastric Bypass Procedure: Frequently Asked Questions


This procedure is a gastric bypass surgery. It is usually not very well known among people. However, in the case your loved one is going to undergo this procedure; then you must have a basic understanding of what it is all about.



This RYGB guide will help you understand some of the frequently asked questions.

  • What is RYGB?

Roux-en-Y bypass is a gastric procedure. Its name is derived from the name of Roux, the French doctor who first performed it. The Y stands for a tube which is shaped in the form of Y resulting from roux limb where small intestine is attached.


The procedure creates a small pouch in stomach which is then reattached to the pouch in the middle of the small intestine. A bypass is thus created which is designed so as to result in reduced food intake. Additionally, the caloric absorption is also reduced due to less intake of food. This procedure is usually used to achieve excellent weight loss. The procedure can take place either through open surgery or laparoscopy.


  • What happens to the food which is unabsorbed?

The unabsorbed food passes out directly from the small to the large intestine. There, bacterial action will occur. However, this is also one of the major risks of the surgery. The bacteria will act upon food to produce gases and irritants which can cause bowel risks.


  • How much weight loss can I expect?

Typically, a patient looses almost 70% of the excess weight in the first 24 months.


  • How much time do I need to recover from the surgery?

Generally, a patient is usually discharged from the hospital for two to four days after the surgery. After the surgery, all normal activities can be resumed in about seven to ten days. But a lot depends on which method was used to perform the surgery. The patients usually have to go for a check-up post operation after a week from surgery.


  • Is there any kind of restrictions on the type of foods I can eat after my surgery?

For the initial time after surgery, the patient is required to stay on a liquid diet. He then gradually moves to a puree diet. Ensuring that the body has adequate intake of liquids is important as there will always be a risk of dehydration.


After some time, preferably a month, the patient can move to the conventional diets. He can start with a combination of regular food with pureed meals. Patients who have undergone surgery will have to incorporate healthy habits such as chewing the food slowly, drinking liquids in between meals rather than during meals and eating the right diet.


  • For whom is the procedure recommended for?

Usually, people who are highly overweight due to some problems like thyroid etc are advised to undergo this procedure. People who are slightly obese or above the normal weight can opt for exercises and fitness routines rather than this method.


  • Is the procedure fully safe?

Surgeries always involve risks. A health concern associated with this process is deficiency of nutrients. As a result, the patients have to take vitamin supplements mandatorily. Apart from this, infections, staples pulling loose and blood clots are some of the other risks.


  • What is the estimated cost of the procedure?


The surgery is a little expensive, somewhere in between $25,000 to $35,000 or more. Make sure you are covered with your health insurance before you settle for the surgery.
