What is roux-en-y gastric bypass surgery?

Roux-en-Y gastric bypass is a bariatric surgery that reduces the size of your stomach to a small pouch just about the size of an egg. The small pouch is separated from the stomach and a segment of the small intestine is bypassed. After this procedure, the amount of food you take in at meals will certainly be reduced.

The procedure causes weight loss due to two factors:

  • The small pouch allows only a small amount of food to be comfortably eaten and creates an early feeling of satiety.
  • The intestine bypass allows for only a significantly lower number of nutrients and calories to be absorbed.

The operation is prescribed to morbidly obese people with BMI over 40 to help weight loss and to also treat co-morbidities. Obesity-associated health conditions (co-morbidities) include sleep apnea, hypertension, type 2 diabetes, coronary heart disease and certain cancers.

The safest technique in gastric bypass most commonly used nowadays is the Roux-en-X gastric bypass, which is performed laparoscopically, under general anesthesia. Instead of a large abdominal incision as it would be the case in an open surgery, during laparoscopy only small incisions are made which permit the insertion of a tiny camera and of the special surgical instruments. Laparoscopy is minimally invasive to the body and allows for precise execution of the operation.

Recovery after Roux-en-X gastric bypass surgery is usually quick, and patients feel minimal discomfort. However, even if chances for complications to occur are low, there are risks associated with the bariatric surgery. Excessive bleeding, infection, blood clots, leaks in the gastrointestinal system are short-term risks that occur rarely. Long-term complications are also rare and they include: gastric dumping syndrome, malnutrition, malabsorption, vomiting, etc. Given that revision surgery is complex, Roux-en-X gastric bypass surgery is only reversed in the case of rare and serious complications.

After gastric bypass surgery, further success and weight loss depend much on the patient and the commitment to diet. The first few days, when the stomach and intestines heal and adjust to the new situations are crucial, and only liquids are allowed. The typical post-operative regime lasts for about 12 weeks and it progresses gradually from liquids through soft and then to regular food. Seek the advice of your surgeon for dietary instructions tailored to your needs.
