How do antibiotics work?
Antibiotics are medicines designed to fight infections caused by bacteria. They work by either killing the bacteria or stopping them from multiplying. Different antibiotics target specific parts of a bacterial cell. For example, some attack the bacteria's cell wall, causing it to break apart, while others interfere with the bacteria’s ability to make proteins or copy its DNA. This helps your body’s immune system clear out the infection more easily.
Why is antibiotic resistance a growing concern?
Antibiotic resistance happens when bacteria change in a way that makes antibiotics less effective or even useless. This can occur if antibiotics are overused (like taking them for viral infections such as colds) or not used properly (like stopping a course too early). Resistant bacteria can spread between people and animals, making infections harder to treat. Without effective antibiotics, even simple infections or routine surgeries could become dangerous. That’s why it’s important to use antibiotics responsibly and only when prescribed by a doctor.
