Weight loss after bariatric surgery sustained long-term! Maciejewski et al in JAMA Surgery


Within three days, this online first by DGIM authors published in JAMA Surgery boasts an altmetric score of 120 — besides tweets, blogs, and facebook, there were 11 news outlets and this one by CBS News: “Do the benefits of weight-loss surgery really last?”

The lead author is Dr.Matthew Maciejewski and the paper is “Bariatric Surgery and Long-term Durability of Weight Loss.” If you ever wondered about gastric bypass surgery outcomes for sustained weight loss, here’s the answer: yes, after 4 years for these 1787 veterans compared to nonsurgical approaches, and this is new news in this research where previous smaller studies were predominately female populations. This was a cohort study with mixed-effects models, a 10-year follow-up between 2000 and 2011.

JAMA Surgery also published an Invited Commentary, “Myths Surrounding Bariatric Surgery” by Jon Gould, MD, Medical College of Wisconsin. The hope is the myth that everyone regains their weight will prove false!

Congratulations, Dr. Maciejewski and team!
