You're probably very aware of the dangers of overusing antibiotics. The more we use antibiotics, the more opportunities we give bacteria to become resistant to them. Plus, antibiotics, especially the newer ones, have some serious side effects and can also wipe out the beneficial bacteria colonizing our guts. This forces us to start from scratch and repopulate them before harmful bacteria can take over and create a whole new set of problems.

Doctors have to get their training somewhere. So they go to medical school. But that's far from the end of the line. Much of what I now know about how to make people well, I learned after medical school, not in it. And medicine keeps changing. New discoveries are made all the time.
