A new study reveals that certain common medications may significantly alter the gut microbiome, potentially impacting overall health. Researchers found that antibiotics, proton pump inhibitors, and some antidepressants can disrupt the balance of bacteria in the digestive system, which plays a key role in immunity and metabolism. The findings suggest these effects could contribute to long-term health risks, though the exact mechanisms remain under investigation. Experts emphasize the need for further study to understand the broader implications of these drug-induced changes.
