Roux-en-Y Gastric Bypass

Roux-en-Y bypass surgery diagramRoux-en-Y bypass is a procedure more commonly known as gastric bypass surgery. In San Francisco and throughout the country, this is the gastric bypass procedure that has been most regularly performed and publicized over the past 20 years.

How It Works

This procedure constructs a small pouch at the top of the stomach to limit meal size, generally to one ounce or less. Approximately 15-20% of the small intestine is bypassed, and a limb of small intestine is joined to the stomach pouch so that digestive enzymes can mix with the food. After 18 months, weight loss can range from 45-75% following this procedure and in many cases is fairly well maintained.

Some of the disadvantages associated with gastric bypass for Bay Area, CA patients include

  • Dumping Syndrome and other gastrointestinal discomforts
  • Higher rate of weight re-gain over time
  • Nutritional deficiencies
