Iron deficiency alters smell, causing unusual cravings

Iron deficiency can alter smell perception, causing cravings for unusual scents like gasoline or chalk. This deficiency affects the central nervous system and dopamine production, impacting how smells are recognized and processed. Patients may experience heightened or reduced sensitivity to smells. The cravings are linked to pica syndrome, a behavioral disorder. Early diagnosis and treatment of iron deficiency are crucial for overall health and preventing neurological issues.
