Question: why do we get sick

Matthew Lee answered on 20 Jun 2017:

lots of different reasons. The main reason we get sick is probably because we have an infection from a bacteria or virus, this is what usually makes you throw up and not want to get out of bed. But we can also get sick from much worse diseases that come from inside us, these can be things like diabetes which if you dont treat well can kill you, or it could be cancer, or even heart disease which is caused mostly by being unhealthy. And then theres also mental health and that has lots of different causes as well. Theres so many things that can make you sick, but we have medicine for nearly all of them!!
