Obesity has become an imminently serious public health problem as nearly 40% of the adult population worldwide is obese. Bariatric surgery is considered the most efficient weight loss treatment by mechanically restricting caloric intake. However, evidence proposes a strong association between weight loss and the alteration of the gut microbial composition after bariatric surgery. Modifications in the concentration of gut microbial bacteria affect human health by either increasing or reducing the likelihood of diseases associated with specific bacteria. In this review, we discuss the effect of bariatric surgery on the gut microbial composition in patients. Additionally, we detail the modifications in the abundance of specific phylum and species in the intestinal microbiota after bariatric surgery. Different disorders associated with the increase or decrease of a particular bacterium are mentioned in order to evaluate the impact of the alteration of post-surgery intestinal microbial structure on individuals’ health.
