Question

The most dangerous symptom of digestive infections is:

fever
dehydration

Answer 1

In most digestive diseases, one of the symptoms is diarrhea.

You know what diarrhea is, right?
It's where you poop out a lot of water. Much more water than you should be pooping out.

Have you ever played Oregon Trail?

If you have, you'd know that on the Oregon Trail, a lot of travelers died from cholera.

Cholera is a bacterial digestive disease.
And what made cholera dangerous was that it would cause people to have severe and uncontrollable diarrhea.
They would constantly poop out water, until they had lost too much water, and died.
