why is too much antibiotics bad for you?

Too much antibiotics can disrupt the balance of beneficial bacteria in the gut, leading to issues like digestive problems and increased susceptibility to infections. Overuse can also contribute to antibiotic resistance, where bacteria evolve and become resistant to treatments, making infections harder to treat. Additionally, excessive use may cause side effects such as allergic reactions or toxicity. Overall, judicious use of antibiotics is essential for maintaining health and preventing long-term complications.
