What Is Duodenal Switch Surgery?

Duodenal switch is a bariatric surgery that helps patients with obesity lose weight. Historically, it was completed using two separate surgeries with the first reducing the size of the stomach using a very similar technique as gastric sleeve and the second part to make alterations to the digestive system much like the gastric bypass. Today it is normally completed during one surgery session.

How Does It Work?
A large portion of your stomach is removed during the surgery, leaving you with a smaller sleeve-shaped pouch that will be your new stomach. You are only able to eat very small portions and you will become full much faster. Your stomach will also not empty as fast, which will keep you feeling full for a longer time. The surgeon makes additional alterations to your digestive system, which changes the pathway the food you eat takes during the digestive process. Your intestines are rerouted to skip a large portion of the normal process and your body is not able to absorb all the calories and nutrients from that food. These changes can lead to significant weight loss.
Procedure Time
2 to 4 hours depending on the complexity of the surgery.

Benefits of the Duodenal Switch

Significant and sustained weight loss: Most patients lose 60-80 percent of their excess weight in the first two years.

Improved metabolic health: Diseases such as type 2 diabetes and high cholesterol quite frequently improve significantly.

Increased satiety: The reduced stomach size means that a person feels full faster, and the malabsorptive component reduces calorie absorption.

Better quality of life: Most patients report having more energy, better mobility, and greater confidence after surgery.

Understanding the Duodenal Switch Procedure

The duodenal switch is a two-part surgery in Seattle. First, the stomach size is reduced, as in a sleeve gastrectomy. That limits the amount of food that can be eaten at one time. Then, the small intestine is rerouted, so fewer calories and less fat are absorbed. Those changes together support long-term weight loss and better management of health issues, such as diabetes, high blood pressure, and sleep apnea.

This surgery is most effective for those with a body mass index of 50 or greater, or for those who have had unsatisfactory results with other methods of weight loss. The duodenal switch incorporates both restrictive and malabsorptive methods that approach the problem of obesity from multiple angles.

Frequently Asked Questions About Duodenal Switch

How does this surgery affect how my body absorbs food?

Duodenal switch surgery alters the way your intestines work, so your body is not able to absorb all the calories and nutrients from the food you eat. This helps you lose weight, but it also means that you need to be deliberate about the food you eat and make sure you take your vitamins and supplements every day.

What kind of vitamins will I need to take after duodenal switch surgery?

Everyone is a bit different, and your surgeon will help prescribe the vitamins and nutrients you will need to take every day. Most likely, you will need a good multivitamin, calcium, iron, vitamin D, and possibly others. Your doctor will use blood work to determine where you may have gaps that require supplementation.

Can I drink alcohol after duodenal switch surgery?

Maybe. After bariatric surgery, alcohol normally affects your system much faster and much stronger. Your surgeon will help guide you on whether alcohol in moderation will be okay for you after you fully heal. Alcohol is also full of empty calories, which can hinder your weight loss efforts or even cause you to gain weight if you are not careful.

How often will I need follow-up visits after duodenal switch?

After duodenal switch surgery, your follow up appointment schedule will be fairly intense, with appointments at 2 weeks, 1 month, 3 months, 6 months, 9 months, and 1 year. After the first year you will need to have a regular scheduled check-up every year for the rest of your life.

What happens if I do not follow the recommended diet after duodenal switch surgery?

Ignoring your dietary guidelines after bariatric surgery can lead to issues like stomach upset, diarrhea, or nutritional deficiencies. It can affect your health and your weight loss results if you do not follow your diet plan.

Is loose skin common after duodenal surgery?

Yes. It is common to have loose skin after you lose a significant amount of weight. The amount of loose skin you will be left with depends on how much weight you lose, your age, and the elasticity of your skin. Some people choose to undergo body contouring surgery to eliminate loose skin later to put the final touches on their transformation.
