A new study reveals how certain common medications may significantly alter gut bacteria, potentially impacting overall health. Researchers found that widely prescribed drugs—including those for high blood pressure, depression, and diabetes—can disrupt microbial balance in ways that may influence metabolism, immunity, and even mental well-being. The findings suggest these effects vary depending on the type of medication and duration of use, raising questions about long-term consequences for patients. Experts warn the results highlight the need for further investigation into how pharmaceuticals interact with gut health.
