A new study reveals that certain common medications may significantly alter gut microbiome composition, potentially impacting metabolic health. Researchers found that long-term use of proton pump inhibitors (PPIs) and antibiotics can reduce microbial diversity, which has been linked to increased risks of obesity and diabetes. The findings suggest these drugs could disrupt the delicate balance of gut bacteria, raising concerns for patients relying on them for chronic conditions. Experts emphasize the need for further investigation into the long-term effects of these medications on overall health.
