Which is Better Duodenal Switch or Gastric Bypass?

Duodenal Switch vs. Gastric Bypass

A study at Cornell Medical Center in New York claims the widely performed weight loss surgery, known as gastric bypass, may not be the most effective in losing weight. The research further claims that a more difficult technique, the duodenal switch, was more effective at generating overall weight loss and body fat loss versus gastric bypass.

Patients Studies on Gastric Bypass and Duodenal Switch

In another study in 2006, researchers from the University of Chicago noted similar results in people with a minimum body mass index (BMI) of 50 that the duodenal switch (DS) resulted in larger loss of weight than the Roux-en-Y gastric bypass (RYGB) by every comparison in patients with a minimum body mass index (BMI) of 50.

In a subsequent study, researchers additionally found that duodenal switch, is more effective at managing obesity-connected conditions like high cholesterol, diabetes, and hypertension.

The results of 350 post-surgery super-obese patients, showed that the duodenal switch had significantly better results versus the gastric bypass.

  • All duodenal switch patients, (one-hundred percent) fully ceased using their medication for diabetes, compared to sixty percent of patients who underwent gastric bypass.
  • Sixty-eight percent of patients who underwent duodenal switch fully ceased taking their high blood pressure medications, compared to thirty-eight percent of gastric bypass patients
  • Seventy-two percent of duodenal switch patients throughly ceased taking high cholesterol related medicines as compared to twenty-six percent of gastric bypass patients

Gastric Bypass patients fared better in one area, and that was acid reflux. Plus, duodenal switch patients may have to go on a vitamin supplement plan due to the modification of the small intestine's ability to absorb nutrients.
