3. Not eating regular meals
If you skip a meal and haven’t eaten in a while, your blood sugar levels may drop. When this happens, your body will release hormones that tell your brain you’re hungry. These hormones can make your blood vessels tighter, which could cause hunger, headache, or even a migraine to start.
Ways to avoid or alleviate pain:
For your body to work well, it needs a steady supply of energy, and food is the main source. So eating and drinking water can help eliminate headaches that come from not eating enough. But if you have a migraine caused by hunger, eating might not be enough to reduce the pain. However, some people have found that a little caffeine can help.
