What Is a Duodenal Switch?

"Duodenal switch surgery is a weight loss procedure that combines a gastric sleeve with a rearrangement of the small intestine to limit the calories your body can absorb. It also helps you feel full from smaller portions. By restricting the calories you consume and absorb, you can lose weight."

Candidates for Duodenal Switch

You may be a candidate for duodenal switch bariatric surgery if:

  • Your BMI is above 55
  • You are 40 or older
  • You have comorbidities like metabolic syndrome, diabetes, hypertension, high levels of cholesterol, type 2 diabetes, sleep apnea, joint pains, or any obesity-related illness
  • You have had unsuccessful bariatric surgery, such as sleeve gastrectomy, and have regained some or all of the weight
  • You have attempted traditional weight loss methods with little or no success

We hear time and again that American patients have been told they are not good bariatric surgery candidates for various reasons. We know this can be utterly heartbreaking. You're not just a number to us. We pride ourselves on helping people with complex needs find a viable solution.

The Duodenal Switch Procedure

An initial consultation is needed first. During your initial consultation, Dr. Martinez will go over your medical history and your weight loss goals to determine if you are a candidate for a duodenal switch. It is important that you let Dr. Martinez know if you have type 2 diabetes, heart disease, or other health concerns. You will then schedule your surgery with our coordinator.

Pre-Operative Tests

On the day you arrive in Tijuana, you will have pre-operative tests run at the hospital. After your tests, you will spend the night in a hotel. 


The following day, Dr. Martinez will perform your surgical procedure, which generally lasts about 120 to 150 minutes. Before your surgery, you will be placed under general anesthesia, which means you will be asleep for the entire procedure.


A small incision is made in your abdomen, and cameras are used to visualize the area. Advanced technology and laparoscopic procedures mean easier and faster recovery times.

Gastric Sleeve 

Gastric sleeve surgery is first performed, removing much of your stomach. This reduces the amount of food your stomach can hold.

Small Intestine Bypass

Dr. Martinez then attaches the end section of your small intestine to the duodenum, and closes off the middle section of your small intestine.

Biliopancreatic Diversion

A biliopancreatic diversion is then performed. The middle portion of the small intestine is connected to the end section of the small intestine. This allows digestive juices such as bile and pancreatic fluids to flow into this newly created section of your intestines.

Closing the Incisions

Dr. Martinez will then remove her surgical instruments and close the incisions. 


You will recover for two days and nights in the hospital so our staff can monitor you closely to prevent any complications. On the evening of your fourth day in Tijuana, you will travel home and continue your recovery there. Over the course of the next several weeks, you will begin to see weight loss results.
