Gastric Bypass vs Duodenal Switch

Duodenal switch surgery may be a better surgical procedure for achieving weight loss and control of comorbidity conditions, especially among the super-obese, according to a study published in the September issue of the Archives of Surgery.

The following chart provides a side-by-side comparison between the two procedures:

Gastric Bypass Surgery

Gastric Bypass Surgery is widely considered the “gold standard” and most common bariatric procedure in North America. Patients who choose gastric bypass vs duodenal switch typically have lower BMIs and are exposed to lower surgical risks compared with duodenal switch surgery.

Duodenal Switch Surgery

Duodenal Switch Surgery is a highly effective surgical weight loss option for morbidly obese patients with BMIs > 50. Studies show that duodenal switch results in superior long-term weight reduction and greater resolution or improvement in obesity-related comorbidities compared with gastric bypass surgery. However, the risk profile is higher for duodenal switch vs gastric bypass.

Considering Gastric Bypass or Duodenal Switch

No matter what type of bariatric surgery you choose – duodenal switch versus gastric bypass… making a serious commitment to behavior and diet modifications is critical to sustained weight loss.
