A new study has recently revealed that obese patients who undergo bariatric surgery have a lower rate of death, compared to the patients who do not have the surgery.
The research done by Jama Network Journals described that people who underwent bariatric surgery, compared with obese patients who did not have this surgery, had a lower all-cause rate of death at 5 years and up to 10 years following the procedure.
It was found that there were a total of 263 deaths in the surgical group, but there were around 1,277 deaths in the control group.
David E. Arterburn, M.D., M.P.H., of the Group Health Research Institute, Seattle, analyzed long-term survival among 2,500 patients who underwent bariatric surgery in Veterans Affairs bariatric centers from 2000-2011 and matched them to 7,462 control patients who did not undergo bariatric surgery.
Bariatric procedures included 74 percent of gastric bypass, 15 percent of sleeve gastrectomy, 10 percent of adjustable gastric banding, and 1 percent of other procedures.
Estimated mortality rates for surgical patients were 2.4 percent at 1 year, 6.4 percent at 5 years, and 13.8 percent at 10 years; for control patients, estimated mortality rates were 1.7 percent at 1 year, 10.4 percent at 5 years, and 23.9 percent at 10 years.
There was no such significant difference was found in the association of bariatric surgery on mortality across groups defined by sex, diabetes diagnosis, and super obesity.
However, the results further provided evidence for the beneficial relationship between surgery and survival that has been demonstrated in younger, predominantly female populations.
The study is published in the journal of JAMA.
