Management of irritable bowel syndrome: a narrative review.

Background and objective: As our understanding of the pathophysiology of irritable bowel syndrome (IBS) has advanced, so too has the therapeutic landscape, offering a myriad of approaches to alleviate symptoms and enhance the well-being of patients. This review paper is dedicated to a comprehensive exploration of the diverse therapeutic modalities available for managing IBS. By delving into the complexities of IBS therapeutics, our aim is to contribute to the enhancement of patient care and the overall quality of life for patients grappling with this complex condition.

Methods: This review utilized information from PubMed/MEDLINE using the key search term "irritable bowel syndrome" as well as the 2020 American College of Gastroenterology (ACG) and 2022 American Gastroenterological Association (AGA) society guidelines on IBS. The search was restricted to articles in the English language only and included peer-reviewed observational studies and randomized controlled trials (RCTs) in adult patients from April 22, 2020 to October 16, 2023.

Key content and findings: This review will start with an overview of the current guidelines for pharmacologic therapies for IBS as recommended by the ACG and the AGA, with an emphasis on clinical trials published after the most recent guidelines. It will then delve into the literature on dietary modifications, probiotics, fecal microbiota transplant, behavioral therapy, and complementary and alternative medicine approaches to IBS.

Conclusions: It is evident that the management of IBS has transcended a one-size-fits-all approach. As the field of IBS management continues to evolve, it is imperative for physicians to stay informed and receptive to the array of therapeutic options available, ultimately providing patients with the most effective and personalized care.
