SYMPTOM
A dull or throbbing head pain that shows up when you've gone too long without eating. It often eases once you have something to eat or drink.

Showing 7 causes
Dehydration
Hunger and thirst cues can overlap, so a skipped meal often comes with skipped fluids too. Mild dehydration is a common trigger for headaches on its own.
Caffeine withdrawal
If your usual coffee or tea is tied to a meal you skipped, the missed caffeine dose could trigger a withdrawal headache as blood vessels in the brain widen.
Blood sugar dip
Going without food causes your blood glucose to drop, and your brain is highly sensitive to this change. This can trigger a dull, steady headache until you eat again.
Migraine triggered by fasting
For people prone to migraines, skipping meals is a well-known trigger. This type of headache tends to be more intense and one-sided compared to a typical hunger headache.
Tension from stress about eating
Feeling rushed, irritable, or stressed while hungry could lead to jaw clenching or shoulder tension, which commonly radiates into a tension-type headache.
Poor sleep the night before
Hunger headaches are often worse after a poor night's sleep, since both low blood sugar and sleep debt affect the same pain-regulating systems in the brain.
Undiagnosed blood sugar regulation issue
Frequent or severe headaches tied to hunger could point to how your body manages blood sugar between meals. This is worth mentioning to a doctor if it happens often.
