Decreased iron and zinc absorption in Turkish children with iron deficiency and geophagia.

Oral iron and zinc tolerance tests were performed in 12 patients between 8 and 21 years of age, with iron deficiency anemia and geophagia. Decreased iron and zinc absorption were detected respectively in patients against the elevated absorption curves in control subjects. Iron and zinc malabsorption may be an additional feature of the syndrome characterized by geophagia, iron deficiency anemia, hepatosplenomegaly, hypogonadism and dwarfism observed in Turkey and Iran.
