"Forever" PFAS chemicals might hamper a teenager's ability to drop excess weight, even if they've undergone weight-loss surgery, researchers said in a study.

Adolescents who undergo bariatric surgery face a higher risk of weight regain, which can undermine treatment success and long-term health, if they have elevated blood levels of per- and polyfluoroalkyl substances (PFAS) prior to the procedure,
