Gastric Bypass

Also known as the Roux-en-Y, gastric bypass is a combination obesity surgery procedure that involves stapling the stomach to create a smaller pouch. Then this new pouch is connected directly to the lower small intestine, bypassing the main stomach and the upper small intestine.

Patients eat less and therefore absorb fewer calories. The smaller stomach and shortened digestion time often lead to successful weight loss in more than 90% of patients. While it can be done laparoscopically, not all patients are candidates for the minimally invasive approach.

Expected weight loss of 75 percent of the patient’s excess weight.  Most patients lose nearly half of their excess weight in the first year following the surgery and continue to lose weight after.

Advantages of Gastric Bypass

  • Rapid initial weight loss
  • Higher total average weight loss than with other bariatric surgeries
  • Minimally invasive approach is possible
  • Longest-used technique in the U.S.

Disadvantages of Gastric Bypass

  • Cutting and stapling of the stomach and bowel are required
  • High risk of complications during surgery than with other procedures
  • Reduced absorption of essential nutrients
  • Medical complications may arise due to nutritional deficiencies
  • Non-adjustable
  • Extremely difficult to reverse
  • Higher mortality rate than with other weight loss surgical procedures

Risks and Early Complications 

Risks and complications are associated with all major surgical procedures. Severe obesity increases the risks of some complications.  They include:

  • Pneumonia
  • Blood clots
  • Infection
  • Ulcers
  • Nutritional deficiencies
  • Fatigue
  • Dry skin
  • Hair thinning or loss
  • Loss of taste or appetite

It’s extremely important to discuss the benefits and risks of weight loss surgery with your surgeon.  You may also attend one of our seminars with family and friends to understand it better. To learn more about gastric bypass, attend a seminar or view a seminar online.
