A new study reveals that certain common medications may significantly alter gut microbiome composition, potentially impacting metabolic health. Researchers found that widely prescribed drugs—including those for diabetes, high blood pressure, and depression—can disrupt the balance of bacteria in the digestive system. The findings suggest these changes could contribute to conditions like obesity and insulin resistance, raising questions about long-term effects of prolonged medication use. Experts emphasize the need for further investigation into how pharmaceuticals interact with gut health.
