Re: Why do I get a headache when I am hungry?

Hi Tina,

The feeling of hunger is combination of low blood sugar and the resulting 
response in your head. This response in your head (brain) is mediated by 
the neurotransmitter (signal substance) Serotonin. 
This substance (serotonin) is involved in a lot of processes, like: sleep, 
mood, thirst, hunger, etc. 
With some people this serotonin system, can cause serious headaches 
(migraine) when it is out of balance. 
In your case it is probably the effect of a sensitive serotonin system, 
which gives you a headache when you are feeling hungry. 
Just try to eat regularly.
