What Does an Iron Deficiency Headache Feel Like?

While we have given you an overview of what can happen cause of low iron, it is important to focus on the headaches. People often neglect these headaches, which later cause a more serious problem.

If you remember the previous section, we mentioned that our blood cells need to carry oxygen to all our organs. This in turn helps the body to work like a well-oiled machine.

Therefore, when we do not have enough oxygen, the first sign is a headache. Let us take the example of a pressure cooker. When our brain does not get enough oxygen, the blood vessels swell up, much like the pressure in a cooker. And just like the pressure cooker which blows off steam, low iron can cause the brain sets off headaches.

This then leads to the other symptoms we have mentioned in the previous section. It is like a chain reaction. When your head hurts, you can’t focus. You start feeling lightheaded. It feels like you may faint. Everything around you turns cloudy and you start to lose your balance. And therefore, when low iron causes headaches, we should not take it very lightly.
