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

998 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?

I can’t answer your question, but it looks like some people have already discussed it, so I ‘m sure you have an answer by now. However, I used to smoke cigarettes and when I would get sick I would not have any nicotine cravings. I actually used that to help myself quit. I had a cold and went several days without smoking. When I started feeling better, the nicotine cravings came back, but not as strong. I wonder if there’s any relation.
