Duodenal Switch

Bariatric Weight Loss Surgery Procedure

How does the DS procedure work?

The duodenal switch (DS), also known as biliopancreatic diversion with duodenal switch (BPD-DS), is a weight loss surgery that combines both restrictive and malabsorptive components. This complex procedure involves the creation of a smaller stomach pouch and rerouting a significant portion of the small intestine. The duodenal switch is typically recommended for individuals with severe obesity who have not achieved success with other weight loss methods.

Restrictive Component

  • Creation of a smaller stomach pouch: A portion of the stomach is removed, leaving a smaller pouch that restricts the amount of food that can be consumed during a meal.

Malabsorptive Component

  • Rerouting of the small intestine: The duodenum (the first part of the small intestine) is divided. The lower part is connected to the remaining stomach pouch.
  • The upper part of the small intestine is then reconnected further down the small intestine, allowing digestive juices from the pancreas and gallbladder to mix with food.


Benefits of Duodenal Switch

  • Significant Weight Loss: The duodenal switch is known for producing substantial weight loss, often leading to a greater percentage of excess weight loss compared to some other weight loss surgeries.
  • Effective Resolution of Obesity-Related Conditions: Many individuals experience improvement or resolution of obesity-related health conditions, including type 2 diabetes, high blood pressure, and sleep apnea.
  • Long-Term Weight Maintenance: The malabsorptive component of the procedure aids in long-term weight maintenance.
  • Improvement in Metabolic Health: Changes in gut hormones and metabolic processes can positively impact insulin sensitivity and other metabolic factors.
  • Reduced Hunger Sensation: Changes in gut hormones often lead to a decrease in appetite and hunger sensation.
  • Potential for Higher Caloric Intake: Individuals may be able to consume a higher number of calories while still losing and maintaining weight compared to some other weight loss surgeries.

“I had a gastric sleeve in 2012 in another state, but the procedure was not done correctly which resulted in minimal weight loss and some complications. I found Idaho BMI and explored my options for a revision, and I’m finally where I want to be. Thank you, Dr. Brown!”

Risks of Duodenal Switch

  • Nutritional Deficiencies:Malabsorption can lead to nutritional deficiencies, including deficiencies in vitamins and minerals such as vitamin D, vitamin B12, iron, and calcium.Lifelong supplementation is often required.
  • Dumping Syndrome: Rapid passage of food into the small intestine can cause dumping syndrome, characterized by nausea, vomiting, sweating, and diarrhea after eating.
  • Longer Recovery Time: The duodenal switch is a more complex surgery, and the recovery time may be longer compared to some other weight loss surgeries.
  • Changes in Bowel Habits: Some individuals may experience changes in bowel habits, including increased frequency and loose stools.
  • Requires Lifestyle Changes: Successful outcomes with the duodenal switch require a lifelong commitment to dietary modifications, regular medical follow-ups, and adherence to nutritional guidelines.
