Weight Loss Surgery | Roux-en-Y

One of the most popular surgical approaches is the Roux-en-Y gastric bypass. This procedure involves modification of the stomach so that only a small amount of food can be eaten at one time.

A small pouch is created at the top of the stomach, effectively shrinking the volume of the stomach to one ounce.

Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum (the first segment of the small intestine) as well as the first portion of the jejunum (the second segment of the small intestine).

Patients lose weight because this small pouch restricts the amount of food that can be eaten comfortably and allows less nutrient absorption due to the intestinal bypass.

Advantages of Roux-en-Y Gastric Bypass:

  • The average excess weight loss in the Roux en-Y procedure is generally higher in a compliant patient than with purely restrictive procedures.
  • One year after surgery, weight loss can average 70 percent of excess body weight.
  • Studies show that after 10 to 14 years, 60 percent of excess body weight loss has been maintained by patients.
  • Patients who underwent a weight loss surgical procedure often experienced complete resolution or improvements of their co-morbid conditions including diabetes, hyperlipidemia, hypertension and obstructive sleep apnea.
