Duodenal Switch Surgery

If your weight has gotten out of control despite exercise and diet, it can be difficult to reclaim your health without help.

If you are struggling with obesity, duodenal switch surgery in Tijuana, Mexico, can give you a new lease on life.

A duodenal switch can produce more significant results than any other weight loss surgery. Could it be right for you?

The Benefits Of Duodenal Switch Surgery

Significant Weight Loss

After a duodenal switch, patients are able to lose around 70 percent of their excess body weight within two years.


Fewer Side Effects

Because the pyloric valve in the stomach remains intact during this bariatric surgery, patients are unlikely to develop dumping syndrome or ulcers.

Proper Stomach Function

A duodenal switch procedure does not alter stomach function in any way.

What Is a Duodenal Switch?

Biliopancreatic diversion with duodenal switch (also known simply as duodenal switch or BPD-DS) is a bariatric surgery that combines a gastric sleeve procedure with a rearrangement of the small intestine to both limit the amount of food required to feel full and limit the number of calories the body can absorb. The combination of restrictive and malabsorptive elements allows patients to experience more dramatic weight loss than gastric sleeve surgery or gastric bypass surgery alone.

During duodenal switch surgery, the surgeon will begin by converting the stomach into a gastric sleeve, removing about 70% of the stomach tissue and reshaping the stomach into a smaller, tube-like structure. Then, the surgeon will rearrange the small intestine so that food does not encounter bile and pancreatic digestive juices until it enters the colon, which limits the number of calories the body absorbs from food.

BPD-DS can be completed as a traditional open surgery or using advanced laparoscopic methods.

A follow-up from my original posting - post surgery has been great and I've been diligent about lifestyle changes. Almost 6 months later and I am down 92 pounds. Everyone says I look completely different and my activity level has greatly increased. I would say my only downfall has been the need to get new clothes!! I've gone from a 40/42 to 36 and some 34's! I would highly recommend Tijuana Bariatrics as an option for weight loss.

Like most weight loss surgeries, duodenal switch surgery is performed under general anesthesia. 


For open surgery, the surgeon will make one large incision in the abdomen. For laparoscopic surgery, the surgeon will make a few small incisions in the abdomen through which to insert a surgical camera and surgical tools.

Gastric Sleeve

The surgeon will begin by essentially conducting a gastric sleeve surgery, removing most of the stomach tissue and stapling the stomach so it becomes smaller and tube-like.

Small Intestine Sections

The surgeon will separate a middle section of the small intestine starting in the middle of the duodenum (the very first part of the intestine) and ending just a few feet before the small intestine meets the large intestine.

Duodenal Switch

The surgeon will connect the few feet of small intestine still attached to the large intestine to the duodenum. Now, food has a much shorter path from the stomach to the colon.

Biliopancreatic Diversion

The surgeon will attach the end of the detached middle section of the small intestine to the large intestine, ensuring that necessary bile from the liver and pancreatic fluid will flow into the colon.

Close Incisions

Your bariatric surgery is now complete. Your stomach can contain less food because of the gastric sleeve, and your body absorbs fewer calories thanks to the duodenal switch and biliopancreatic diversion. The surgeon will stitch your incisions shut, and your recovery can begin.

Enjoy a Near-Normal Diet  after Surgery

One of the main reasons patients opt for BPD-DS over other forms of weight loss surgery is the post-procedure diet.

The techniques used in this form of bariatric surgery do not interfere with the ability of your stomach to function.

A duodenal switch procedure allows you to eat normal, healthy portions of food without difficulty while still limiting the number of calories you intake for dramatic weight loss.

How Does a Duodenal Switch Compare with Other Bariatric Procedures?

Duodenal switch surgery is one of the most complex weight loss surgeries and is usually reserved for patients with extreme obesity. Aspects of duodenal switch surgery are similar to either gastric bypass surgery or gastric sleeve surgery, but there are notable differences, as well. Our bariatric surgery office in Tijuana, Mexico, coordinates all of these procedures here in Tijuana. Review the similarities and differences among the different procedures to help decide which could be right for you:


  • BPD-DS, gastric bypass, and gastric sleeve all involve some degree of creating a smaller stomach pouch, resulting in patients requiring less food to feel full.
  • Gastric sleeve surgery, gastric bypass, and duodenal switch surgery all produce hormonal changes in the gut that can reduce appetite.
  • Gastric sleeve surgery, gastric bypass surgery, and BPD-DS all involve changes to the anatomy that cannot be reversed.


  • Duodenal switch surgery usually leads to greater weight loss than a gastric bypass or gastric sleeve, around 70% of excess weight.
  • Duodenal switch surgery has a higher complication rate than gastric bypass surgery or gastric sleeve surgery.
