Reportedly, toxic artificial chemicals—like PCBs (polychlorinated biphenyls) and OC (organochlorine) pesticides—that are imbibed in the body and accumulated in fat might be discharged into the bloodstream at the time of the rapid fat loss that follows bariatric surgical procedure. The study was led by researchers from the JHSPH (Johns Hopkins Bloomberg School of Public Health) and the finding directed to the need for more research to know the health impacts of this latent toxicant exposure. The study findings were published in the journal Obesity.
Scientists analyzed 26 people undergoing a bariatric weight-loss surgical procedure and discovered evidence of post-surgery increases in the blood levels of environmental toxicants that are well-known to be stockpiled long term in fat, counting PCBs, OC pesticides, and PCB-like PBDEs (polybrominated diphenyl ethers). The study also stated that volunteers born prior to 1976—when the majority of the chemical compounds were still broadly used—were likely to have higher bloodstream levels of the chemicals, in correlation to younger volunteers. John Groopman—Study’s Senior Author and Professor at the JHSPH—said, “The truth that this ever more popular type of surgery might be causing these compounds to be discharged in the blood actually challenges us to realize the potential health consequences.”
On a similar note, recently, a study showed cancer risk declined to half with more than 20% weight loss following bariatric surgery. The patients having chronic obesity and who had weight-loss or bariatric surgery lost over 20% of their entire weight were 50% less inclined to advance cancer than patients who did not have much of weight loss subsequent to surgery, as per to a new study. The research was presented by researchers from the Oregon Health & Science University during the 36th ASMBS (American Society for Metabolic and Bariatric Surgery) Annual Meeting at ObesityWeek 2019.
