When you’re sick, why does your appetite often go away?

993 views

I’ve noticed that with certain sicknesses, I tend to go most of the day without eating anything; if not all day. Usually just for one day though, then I get my appetite back. Normally (when I’m not sick) if I go a few hours without eating I get “hangry”. I’m used to eating quite a lot throughout the day though because I have a fast metabolism. So (for me it happens with tonsillitis or stomach bugs) why is it that when you’re sick you don’t feel inclined to eat? Doesn’t your body need food for energy to fight the sickness? And why does it seem that only certain sicknesses suppress the appetite?

Perhaps it’s because if food made you sick, a probationary period where you don’t eat is a good idea? That way you don’t continue to ingest more of the virus or bacteria.
