Gastric ByPassastric Bypass

Roux-en-Y Gastric Bypass

This operation is the most common weight loss surgery done in the United States.

  • It is a combination of restriction and malabsorption.
  • A small stomach pouch is stapled and separated from the remaining stomach.
  • This smaller stomach pouch is the size of a ping-pong ball and holds less than 1/2 cup of food.
  • Staples cannot “pop” and the stomach pouch is only able to stretch a small amount.
  • Food is redirected directly to the jejunum, part of the small intestine.
  • This operation is done on the short side of the stomach which is much less apt to stretch, hence better long term success.
  • The amount of food you can eat at one time is small.
  • Because part of the stomach and small intestine are bypassed, the amount of calories and nutrients your body absorbs is limited causing malabsorption, or poor absorption.
  • One hundred percent of patients will lose weight. Patients have maintained 60 percent weight loss 14 years after surgery.
  • Long-term safety has been shown and patients have been able to keep the lost weight off.
  • Requires long-term follow up with doctor.
  • Requires you to take vitamins/nutritional supplements the rest of your life.
  • We offer a choice of open or laparoscopic techniques. This will be discussed with your surgeon.
