Headaches and Migraine
Headaches may be caused by several circumstances, including low oxygen levels in the brain. On the other hand, migraine pain is often characterized as a throbbing feeling on one side of the head. Frequent migraine episodes may accompany symptoms such as visual abnormalities or sensitivity to light or sound that are often severe and persistent.
Migraines, headaches, and heightened pain sensitivity have all been linked to iron deficiency anemia. It is unclear exactly how these effects occur, but decreased oxygen transport to the brain reduces the energy it can utilize and may cause mental and physical exhaustion. Anemia causes organs not to operate effectively. When this occurs in the brain, the brain’s blood vessels enlarge and generate the pressure that causes a headache. This pressure may also induce lightheadedness or vertigo.
Also, iron deficiency caused by menstrual blood loss may contribute to menstrual migraines, particularly when they occur at the end of a woman’s period. Some have classed this migraine as a distinct kind of headache. Researchers hypothesize that iron deficiency and headaches are connected by several variables, including the association between altered dopamine function and estrogen levels. Lastly, over-the-counter pain medicine may treat most headaches caused by anemia.
