Roux-en-Y Gastric Bypass Procedure

It is important to remember that this weight-loss surgery, like all others, is considered a "tool,” and one must adhere to diet, exercise, support and counseling to achieve maximum results.

  • The surgeon creates a smaller stomach pouch with the existing stomach.
  • He bypasses the larger portion of the stomach and part of the small intestine (duodenum and some of the jejunum).
  • The newly created pouch is then attached to a part of the intestine below the bypass.
  • This limits the amount of food the stomach can hold (restriction) and causes food that is eaten to be poorly digested and absorbed (malabsorption). The result is that the patient cannot eat as much and they absorb fewer nutrients and calories.

Patients report a feeling of fullness right after surgery. In the beginning, a patient may only be able to consume ¾ cup of food at one sitting. This will increase to one-two cups after one-two years. Vitamin and mineral supplements and a high protein intake will be required for life to prevent nutritional deficiencies.
