A Simple Guide to the Duodenal Switch


The type of weight loss surgery known as the duodenal switch is regarded as an excellent option for significant weight loss when performed by an experienced bariatric surgeon.

What are the benefits of the duodenal switch?

  • Statistics have shown the DS has the highest percentage of weight loss of any bariatric surgery
  • Will be appropriate for people who have a high-fat diet
  • Doesn’t result in the “dumping syndrome”
  • Has the highest resolution rate for diabetes, high cholesterol, and high blood pressure Drastically reduces hunger and appetite
  • Has a better record for weight loss than the Lap-Band and gastric bypass for morbidly obese patients


How Does The Duodenal Switch Work

Patients lose weight with the duodenal switch procedure because it restricts the amount of food that the stomach can take in, and it limits the number of calories that can be absorbed by the body.
Basically, the duodenal switch works for two reasons: restriction and malabsorption, which are essential for long-term weight loss.
In a vertical gastrectomy or sleeve gastrectomy, the size of the stomach is greatly reduced – by about 85% - and thus eating is restricted.
The duodenal switch or intestinal bypass work through malabsorption. The intestines are divided and rearranged to separate food from the digestive juices, thereby creating malabsorption, or minimizing the calories that are absorbed into the system.

Advantages of Duodenal Switch

There are a number of noteworthy advantages of the duodenal switch weight loss procedure:
  • The estimated weight loss following the procedure is more than 90% of the patient’s excess weight
  • The procedure has a 99% success rate in resolving diabetes
  • The resolution rate for obstructive sleep apnea is 99%
  • The success rate for resolving high cholesterol and triglycerides is 90%
  • Resolution rate of hypertension is more than 90%
  • There is generally no “dumping syndrome” following surgery
  • The portion of the stomach that stores the hormone which stimulates hunger will be removed during surgery, and this drastically reduces hunger pangs and appetite
  • There is no high likelihood of developing ulcers due to anti-inflammatory medication
  • Patients who experience malabsorptive complications may have the intestinal bypass partially reversed
  • The surgical procedure is done with a totally laparoscopic approach, making large incisions or handports unnecessary


Risks of Duodenal Switch

While the disadvantages of the Duodenal Switch weight loss surgery are fewer, a few remain, including:
  • A greater likelihood of experiencing chronic diarrhea, foul smelling stools and gas
  • The possibility of developing anemia, vitamin deficiency, protein deficiency and osteoporosis in about 10-15% of patients, caused by significant malabsorption
  • Abdominal pain or cramps, as well as long-term regaining of weight and limited weight loss, all caused by excessive carbohydrate intake
  • The likelihood that high-risk patients may want to consider one of the other types of weight loss surgery, as the duodenal switch is extremely complex and the operation time is longer
