Abstract:
Obesity is a complex, multifactorial disease that is associated with significant morbidity and mortality. Recent research in bariatric surgery has shown that these surgeries can impact the composition of the gut microbiome. Postoperative alterations include increased microbial diversity and shifts in composition, such as a change in the Firmicutes/Bacteroidetes ratio. The interplay between altered gut anatomy, dietary changes, and microbiome composition creates a metabolically favorable environment that contributes to the long-term success of bariatric surgery. This review focuses on the overall impact of bariatric surgery on the gut microbiome and potential targeted therapies that can be used to improve outcomes.
