Impact of bariatric surgery on multiple health outcomes: a protocol for umbrella review of systematic review and meta-analysis

ABSTRACT The number of bariatric surgery rises as the prevalence of obesity and metabolic comorbidities consistently increases[1]. Although bariatric surgery was originally developed for glycemic control and weight reduction, increasing evidence suggested extra-metabolic health outcomes are followed by bariatric surgery; incidences on diverse types of cancer[2], perinatal outcomes[3], sexual function[4], and even degree of physical activity[5] are known to be altered after bariatric surgery. We aim to conduct umbrella review for metabolic and other multiple health outcomes following bariatric surgery, and systematically appraise the context and quality of the relevant evidence.
