Why does hunger cause headaches?

When I don't eat after 6 or 7 hours, I start having a headache. It disappears after eating. Why is that?
It's not uncommon to develop a headache when you are very hungry - the kind of hunger that comes from strenuous dieting or skipping meals. That kind of hunger is the result of low blood sugar and muscle tension that comes from missing a basic biological substance (food). On the hunger-satiety scale, that would be a 0-1. But the good news is, as you saw, hunger headaches are easily prevented and treated by eating nourishing meals that contain adequate calories, protein and complex carbohydrates on a regular schedule.
