What is a consequence of the overuse of antibiotics?

The overuse of antibiotics leads to antibacterial resistance, which is a significant public health concern. When antibiotics are used excessively or inappropriately, bacteria can adapt and evolve in response. This adaptation includes genetic changes that equip them to survive exposure to the drugs that were once effective at killing them or inhibiting their growth. As a result, these resistant bacteria can proliferate, making infections harder to treat.

The consequences of antibacterial resistance are profound. It can lead to longer hospital stays, higher medical costs, and increased mortality rates. Additionally, treating infections caused by resistant bacteria often requires more extensive and expensive interventions, such as the use of stronger or combination therapies that may have more side effects.

Understanding this concept is vital in addressing antibiotic stewardship and ensuring that these critical medications remain effective for future patients.
