The benefits of Roux-en-Y gastric bypass surgery appear to persist over a decade, according to a study in the New England Journal of Medicine.
Researchers studied over 400 people with severe obesity who underwent Roux-en-Y gastric bypass, 400 who sought the procedure but did not receive it, and 300 obese people who did not seek or undergo surgery.
At 12 years, the surgery group had lost 27% of their body weight, compared with 1%–2% among patients who didn’t have surgery. The surgery group was also at lower risk for developing type 2 diabetes (3% vs. 26%), hypertension, and dyslipidemia. Of patients in the surgery group who had diabetes remission at 2 years, 69% were still free of diabetes by year 12.
