Gastric Sleeve VS Duodenal Switch Surgery


Here at Weight Zen, Dr. Rosen works with hundreds of patients looking to get their lives back. Are you exhausted by fad diets and exercise routines that simply don’t work? Dr. Rosen helps individuals who suffer from obesity and similar issues through bariatric surgery in New York. We offer such bariatric surgery options as Gastric Bypass, Gastric Sleeve, the Lap-Band, Duodenal Switch, and the Orbera Gastric Balloon.

Today, we’re going to take a specific look at the difference between the Gastric Sleeve and Duodenal Switch surgical procedures for weight loss.

What Is The Gastric Sleeve Surgery?

Simply put, Gastric Sleeve surgery is a type of bariatric surgery intended to help those with their weight loss efforts. During the procedure, the size of the stomach is dramatically reduced, meaning that the patient becomes full sooner when eating and thus eats fewer calories overall.

What Is The Duodenal Switch Surgery?

The Duodenal Switch surgery, also known as a biliopancreatic diversion with duodenal switch (BPD-DS), reduces the size of your stomach by up to 70 percent. Additionally, this weight loss surgery reroutes part of your small intestine to create two different pathways from your stomach: one brings in food from your stomach to a common channel of your small intestine, and the other helps carry bile to the same common channel from your liver. This helps to prevent your body from absorbing calories from the food you eat (part of the digestive process).

Two Different Mechanisms For Weight Loss

As you may have noticed, these weight loss surgeries offer two different types of weight loss mechanisms: malabsorptive and restrictive.

Malabsorptive bariatric surgery limits the amount of calories your body absorbs during the digestive process, whereas restrictive bariatric surgery limits the amount of calories you can consume while reducing the sensation of hunger.

Gastric Sleeve surgery is a clear, restrictive weight loss procedure, while the Duodenal Switch combines restrictive and malabsorptive mechanisms within the surgery.

Advantages Of The Gastric Sleeve Surgery

This is a far less complicated surgery compared to the Duodenal Switch weight loss surgery as it only requires a change in the overall size of your stomach rather than a total rerouting part of your small intestine. Not only does the Gastric Sleeve surgery help with weight loss efforts, but it is also low-risk with regard to post-surgical complications.

Advantages Of The Duodenal Switch

The Duodenal Switch is much more complicated than the Gastric Sleeve surgery and has increased risks. However, the Duodenal Switch has been proven to be successful at helping patients lose more excess body mass and weight. This is due to the fact that this procedure incorporates both malabsorptive and restrictive weight loss.

The Duodenal Switch Can Be Used After A Gastric Sleeve

If you aren’t seeing the results you and your doctor want from the Gastric Sleeve surgery, the sleeve is able to be transformed into a duodenal switch to help with weight loss efforts.
