The Duodenal switch surgery is a weight loss procedure. It uses restriction and malabsorption to aid weight loss for patients with obesity.

This is a proven, effective way to lose weight and improve obesity-related health conditions.

Duodenal Switch Surgery

Biliopancreatic diversion with duodenal switch (BPD-DS) surgery is a two-part procedure. During the procedure, roughly 75-80% of the stomach is removed, in a way like gastric sleeve.

Then, a small stomach pouch is created. The newly created stomach pouch is connected to the last portion of the small intestine, called the duodenum.

After the procedure, the food you eat empties directly into the duodenum, bypassing about 75% of the small intestine. This means the body absorbs fewer calories and nutrients. Also, duodenal switch surgery impacts gut hormones to reduce hunger, control blood sugar levels, and increase satiety.

Pros and Cons

The pros of duodenal switch surgery are rapid weight loss, the highest average expected weight loss among bariatric procedures, and it is 98% effective in curing diabetes.

Because the stomach is so small, you only eat a small amount of food. Then, because the path food travels is shortened, you absorb fewer calories. This creates rapid weight loss.

The cons of the procedure are that it is not reversible, it is the most complex weight loss surgery, and there is a possibility of vitamin and mineral deficiencies.

Duodenal switch surgery requires a very strict diet and vitamin supplementation to avoid malnutrition. You will also have to eat soft foods for a while before transitioning to solid food again.

Am I a Candidate for Duodenal Switch Surgery?

To be eligible for duodenal switch surgery, you must be morbidly obese or superobese (BMI over 50) and you need to be healthy enough to undergo surgery.

People who have obesity related health conditions, like diabetes, are good candidates as well. Your physical will evaluate you and help you decide if this is the right type of bariatric surgery for you.

As with other bariatric surgeries, duodenal switch surgery will work best for patients who are committed to weight loss and maintain a healthy lifestyle.

Your provider will recommend a diet and exercise program to help you achieve optimal results.
