A new clinical study identifies a significant link between iron deficiency anemia and migraine headaches.
Research from Mymensingh Medical College Hospital compared 155 migraine patients with 155 healthy controls. The analysis found iron deficiency anemia was far more common in the migraine group.
The association was especially pronounced in women, who showed significantly lower levels of serum hemoglobin and ferritin. In men, lower ferritin levels were also significant.
Furthermore, the study revealed a link between iron deficiency and migraine severity. Patients with severe headaches had lower hemoglobin and ferritin levels, with statistical significance.
These findings suggest that depleted iron stores may be relevant to migraine biology. Researchers hypothesize iron deficiency can contribute to brain metabolic abnormalities and reduced neuronal activity.
While the study shows correlation, not causation, it suggests screening for iron deficiency could be clinically valuable for migraine patients, especially those with severe attacks.
