I’ve been becoming very dizzy when i quickly stand up from either sitting or standing, I feel like I’m about to pass out, people keep telling that it is because of an iron deficiency, how does that cause the dizziness?
Your blood needs iron to transfer oxygen and the brain is very sensitive to a lack of oxygen. Standing up quickly lowers the blood pressure in your brain anyway and if you have a lack of iron and therefore red blood cells already it can make you feel very dizzy or pass out.
