Why do I feel so hungry,but it doesn't signal my brain?

I've been sick with the flu 2 days ago(I feel just fine now) and had eaten nothing but tylenol(acetaminophen) at that period of time, now I feel hungry but my head just don't get it(there's no signal that tells my brain I'm hungry like there used to be), this never happen before..Its been 2 days past since I've eaten any extra tylenol. Is it like after effects of tylenol? Should I go see my doctor?

Has this happen to you before, did you recover from it? What should I do? Will it go away?

However, here are a two ideas. First off, if you were ill with the flu for several days and did not eat any food during that time period, your body may have gone into a kinda of a "diet" or "starvation" mode. For most people, after two or three days of not eating, and in particular not eating sugar and carbohydrates, their body chemistry changes and instead of using mostly carbohydrates from food for energy, the body uses mostly fat (from food or from body fat stores) for energy.

(This is the principle behind low-carb diets like Atkins. ) Once your body gets into that state, you may not feel hunger as strongly as you used to. When I've started low-carb diets, I have days when I notice my stomach feels empty (is that what you mean by "hunger"?

) but I really don't feel too compelled to fill it up with food, because I have plenty of energy and feel fine just using up the old body fat. If this is the state you are in, just make yourself eat a little something and you'll notice your appetite return in no time (especially if you eat something sugary and switch your body chemistry back over to using carbohydrates for energy). Now, with not eating due to the flu (as opposed to eating low-carb on a diet), you can avoid the "no energy from food" problem if you are relying on body fat, but you can't avoid the "no nutrients from food" problem.

If you don't start eating food again soon, your body will have to start destroying muscle and other body tissue to get the nutrients that your brain and heart need to survive. This is a very bad state to be in, and you should see a doctor if you go more than four or five days without being able to keep food down. Second idea, you mentioned taking "extra tylenol".

If by "extra" you mean more than the recommended dosage on the label, then there is a good chance you damaged your liver. This is something that you should also see a doctor about soon, especially if you have side effects like changes in appetite or energy levels or notice any yellow tint to your skin or the whites of your eyes..

The white cells fighting the virus infection release chemicals that cause us to lose our appetite. Here's some infomration that addresses you questions:"Why do we feel tired and lose our appetite when we have a cold? The white cells fighting the virus infection release chemicals (cytokines) that circulate in the blood to the brain and cause us to feel tired and lose our appetite.

This is nature’s way of forcing us to rest so that our body can focus on fighting the infection. In the past, searching for food would have involved much work and effort, therefore it would have been beneficial to rest and go without food for a few days"Hope this helps!

How do you feel about some countries that have free health care for their people.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
