Eli5: If there are billions of bacteria in our body, why is it bad for someone to just pop some anti biotics even without being sick

Antibiotics kill bacteria. There are billions of bacteria in our body. Why is it drug abuse if I just decide to toss in a few in my mouth, without being sick, since there would always be bacteria to kill

You’re using a drug for no good reason which generally classifies as abuse. Beyond that:

– Most of these bacteria are beneficial to your digestive functions

– The presence of beneficial or neutral (commensal) species blocks disease-causing species from gaining a foothold, because competition is stricter

– You’re contributing to the generation of antibiotic resistance

These are issues that are present anytime you take antibiotics. The need to clear out disease-causing bacteria may outweigh them, but when there is no such need you are strictly hurting your health (and that of others through resistance).
