A new study reveals that certain common medications may significantly alter gut bacteria in ways that could impact long-term health, potentially increasing susceptibility to infections and metabolic disorders. Researchers found that even short-term use of widely prescribed antibiotics and proton pump inhibitors can disrupt microbial balance, with effects persisting long after treatment ends. The findings suggest a growing need to weigh the broader implications of these drugs beyond their primary therapeutic benefits. Experts warn that further investigation is required to fully understand the risks and develop safer alternatives.
