How does NASA ensure that astronauts going into space for months at a time don’t get sick?

Question

I assume the astronauts are healthy, thoroughly vetted by doctors, trained in basic medical principles, and have basic medical supplies on board.

But what happens if they get appendicitis or kidney stones or some other acute onset problem?

In: 2048

Answer 1

The only remote workers who must undergo prophylactic appendectomy are doctors who stay over winter in Antarctica. They can’t (or rather they really shouldn’t) take our their own appendix and they certainly can’t get back to civilization in time to treat appendicitis. An astronaut can.
