Let's not forget to mention that these resistant bacteria start to spread, making antibiotics less and less useful over time, for everyone.

We're already at a place where antimicrobial resistance has become a huge issue, rendering treatments with antibiotics useless in many cases.

If you ever suffered through a bacterial infection and remember how you felt once the antibiotics finally kicked in, and the prolonged suffering resistances would cause, or ever watched a loved one in a hospital die from a bacterial infection just because the were in a weakened state and the stem they caught was already resistant, you'll understand why that sucks so much as it does.

That was the theory and how it works in a petri dish, however that's not how it works in the body.

Antibiotic treatment doesn't have to kill all of the bacteria. It needs to kill enough so the immune system can catch up and finish the job.

There been evidence for more than 50 years that overly long antibiotic treatments cause resistance to build up faster. That's why they have limits on the first place.

So there's a balance between too few days, and to many.

Funny how these "assumptions" are proven wrong but still everyone regurgitates them.

Don't eat eggs, because they increase your cortisol... is another one of these myths

There is nuance here and it's up to medical professionals and researchers to find the right balance. The biggest source of the unnecessary usage of antibiotics is rampant over-prescription, not taking a few more doses after the first second you feel better. Rebounding with a more resilient infection after stopping antibiotics early is still a relevant concern and happens frequently.
