Does antibiotics really destroy the gut flora?

Concerns about antibiotics include their potential to disrupt beneficial gut bacteria and contribute to antibiotic resistance. While antibiotics can have side effects like diarrhea and nausea, they are essential for treating bacterial infections. It's crucial to use them only when prescribed by a doctor to avoid unnecessary risks. Local antibiotics target specific areas without affecting the entire body, unlike systemic ones. Proper diagnosis and targeted treatment are vital to ensure antibiotics are used effectively and to maintain their long-term efficacy.
