Duodenal Switch for Substantial Weight Loss


Illustrated diagram of how duodenal switch surgery changes the route of the intestines

Not all bariatric surgery is created equal. For patients who hope to lose a substantial amount of weight, Dr. Liza María Pompa González may recommend a duodenal switch. This special type of bariatric surgery combines the restrictive techniques of a gastric sleeve with the malabsorptive benefits of a gastric bypass to enhance weight loss.

If you are at or above 40 BMI or if you suffer from weight-related health problems like hypertension or type 2 diabetes, you may qualify for this procedure. The team at LIMARP®️ in Tijuana, MX, can evaluate your condition and health goals and determine the best treatment plan for you.

Duodenal Switch Surgery

As a restrictive procedure, a duodenal switch physically restricts the amount of food you can eat by removing approximately 75 percent of the stomach so that it is about the same size and shape as a banana. This reduction in stomach capacity helps patients to feel full faster and with less food, a key to significant weight loss. Compared to other surgeries that reduce stomach size, the duodenal switch leaves a larger portion of the stomach and small intestine intact.

Another component to this weight loss surgery is changing how the patient digests and absorbs food, an effect known as malabsorption. By rearranging the layout of the small intestine, Dr. Pompa can separate the flow of food from the secretion of digestive juices. This consequently restricts the uptake of fat-based calories. Because they do not absorb fat, patients do not form any new fat tissue, either.

Determining Candidacy

Duodenal switch patients typically experience more dramatic weight loss compared to patients undergoing other bariatric procedures. In fact, most patients lose at least half their excess weight within a year of their surgery. However, there is consequently potential for nutrient deficiencies due to malabsorption. As such, this surgery is typically recommended for patients at or above 40 BMI (body mass index) or patients who suffer with weight-related health problems, such as:

  • Type 2 diabetes

  • Heart disease

  • Hypertension

  • Snoring and obstructive sleep apnea

During your first discussion with the doctor, she and the team can evaluate your medical history and weight loss goals to determine whether a duodenal switch is appropriate.

Advantages of the Procedure

Duodenal switch patients often enjoy dramatic weight loss while still being able to eat their favorite foods. Additionally, because of how the stomach is reshaped, there is a much lower risk of digestive complications such as ulcers, blockages, or dumping syndrome compared to other restrictive procedures.

The procedure can also relieve a number of weight-related health issues. Patients may find that their back and joint pain is alleviated, they have improved energy, or their diabetes is better under control. These improvements in how patients feel go far in boosting mental health and sense of self.
