What is the Duodenal Switch?
The Duodenal Switch (DS) is a weight loss surgery that involves making changes to the stomach and small intestine. It’s considered one of the most effective procedures for long-term weight loss and improving weight-related health problems.

Common Questions about Duodenal Switch
The DS has two main parts:
Making your stomach smaller: The surgeon removes a large portion of your stomach, leaving a smaller tube-shaped stomach, similar to a banana. This limits how much food you can eat at one time.
Rerouting your digestive system: The surgeon bypasses a portion of your small intestine. This means your body absorbs fewer calories and nutrients from the food you eat.
Benefits of the Duodenal Switch:
- Significant weight loss: The DS helps you lose a greater amount of weight compared to other weight loss procedures.
- Long-term results: Many people keep the weight off for good after having a DS.
- Improved health: The DS can help improve or resolve health problems like type 2 diabetes, high blood pressure, and sleep apnea.
The DS is typically recommended for people who:
- Have a BMI of 40 or higher, or a BMI of 35 or higher with serious weight-related health problems.
- Have tried other weight loss methods without success.
- Are committed to making lifestyle changes after surgery, including following a special diet and taking vitamin supplements.
You’ll need to follow a special diet and take vitamin supplements for life after the DS. You’ll also have regular checkups with your doctor to monitor your progress.
