Yes, you suffer from hunger headaches when you don’t eat properly. When your blood sugar begins to drop below normal levels, you experience a hunger headache. Long stretches between meals increase your risk of suffering from hunger headaches.

How to Cure a Headache From Not Eating

Headaches caused by hunger are your body’s method of telling you that you need calories. They do not vanish by themselves. A balanced breakfast with protein, vegetables, fruits, and carbohydrates is the best treatment.

You should be aware that your body may need 15 to 30 minutes to adjust and replenish its blood sugar storage. You might need to eat anything with a lot of sugar if you feel like your blood sugar is particularly low or if you have a history of hypoglycemia.

Examples of such foods are fruit juice or soda. Just remember to consume some protein later.

You could occasionally have hunger headaches while fasting. Planning can help you reduce your risk.

A couple of days before fast:

  • Increase the amount of water you’re drinking
  • Avoid caffeine
  • Eat nutritious meals

For the meal before fast:

  • Avoid consuming meals that are bigger than usual.
  • Potatoes and other starchy vegetables are good sources of complex carbs. Combine them with some protein.

The majority of people do not require medical attention for a hunger headache. However, if your symptoms are severe or don’t go away with painkillers, you could need medical attention.
