ROLE OF PROBIOTICS IN RESTORING GUT MICROBIAL BALANCE AFTER ANTIBIOTIC THERAPY – A REVIEW

Abstract

Human gut microbiota plays an essential part in keeping gastrointestinal health steady, it also helps with immune function and basically acts like a shield against pathogenic microorganisms. But when someone goes into antibiotic therapy it can disrupt the composition and diversity of the gut microbiota, then it moves toward dysbiosis, and that situation is tied to a higher risk of antibiotic associated diarrhea and other bowel issues. Probiotics, meaning living microorganisms that can offer health advantages when they are given in sufficient amounts, have been getting a lot of attention as a sort of supportive strategy to help the gut microbial community rebound after antibiotics . In this review we want to look at how probiotics might help bring back a more steady gut microbial state after antibiotic exposure, with focus on the mechanisms, the real clinical results, safety concerns, and potential therapeutic roles . We went through relevant scientific work, including research articles, clinical trials, systematic reviews, and meta-analyses. We searched databases like PubMed, Scopus, Google Scholar and Web of Science. Overall the evidence we reviewed suggests that some probiotic strains, especially certain Lactobacillus and Bifidobacterium types, along with Saccharomyces boulardii, could help lower the incidence of antibiotic associated diarrhea, support the intestinal barrier and back general gastrointestinal comfort. Still, how effective they are seems to depend on the strain, the dose, the treatment duration, and also the individual patient. On top of that, whether the original gut microbiota truly returns is not fully consistent. So, in conclusion probiotics may work as a useful extra alongside antibiotic therapy, mainly by lowering certain gastrointestinal complications while supporting gut health. More clinical research is needed, to pin down the best probiotic strains, the proper dosages, and the treatment durations that are both effective and safe for real-world use.
