What is Duodenal Switch Surgery?

The duodenal switch reduces the amount of food your stomach can hold and the amount of nutrition absorbed by your intestine. It also reduces the hunger hormones produced by your stomach and intestine, so you don’t suffer from hunger pangs that make you overeat. This procedure is for patients with a high BMI and a history of previous bariatric surgeries.

Why is Duodenal Switch Done?

The duodenal switch is generally recommended for patients with clinically severe obesity, especially those with a high risk of obesity-related diseases, such as high blood pressure, high cholesterol, kidney disease, diabetes, and heart disease. You are generally considered a candidate for a duodenal switch if you have a BMI of 50 or more or severe forms of obesity-related diseases.

Benefits of Duodenal Switch Surgery:

  • Reduces your Ghrelin levels, which decreases your hunger pangs and the desire to overeat
  • Decreases the volume of your stomach, which makes you feel full faster and eat less
  • Reduces the calories absorbed by your body, leading to sustained weight loss results
  • Improves insulin secretion and reduces the symptoms of type 2 diabetes
  • Decreases your level of bad cholesterol (LDL cholesterol)

Drawbacks of Duodenal Switch Surgery:

  • Irreversible procedure that removes up to 80% of the stomach
  • Inherent risks associated with removing part of the gastrointestinal tract
  • Increased risk of malnutrition and dehydration because of nutrition restriction
  • You must take vitamin and mineral supplements to prevent malnutrition

Your Duodenal Switch Procedure

Dr. Ahuja performs advanced duodenal switch procedures using minimally invasive laparoscopic and robot-assisted techniques. Depending on your unique condition, the procedure may be performed in one or two stages. The duodenal switch surgery has restrictive and malabsorptive components that work together to reduce and keep off weight. Dr. Ahuja will curate a personalized surgical plan for you and describe the details of the procedure in advance.

Step 1: Sleeve Gastrectomy

The first step of the duodenal switch procedure involves creating a sleeve to reduce the size of your stomach. After making a few small incisions, the surgeon removes 70% to 80% of your stomach, including the part of the stomach that makes the Ghrelin hormone, which is associated with hunger pangs. Reducing the size of your stomach also makes you feel full faster.

Step 2: Intestinal Bypass

The second step of the duodenal switch procedure involves bypassing the small intestine to reduce the volume of calories and nutrition absorbed from food. The surgeon connects the last part of the small intestine to the part located close to the stomach, effectively bypassing most of the small intestine. The intestine is repositioned to ensure you absorb less food.
