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.
