Question
My daughter is 1 year and 11 months old and has been diagnosed with iron deficiency anemia, but she shows no obvious symptoms and does not have any pica. The fontanel has not closed, measuring about 0.5*0.5cm. Although iron and calcium supplementation has been initiated, the results have been unsatisfactory.
Answer
The fontanel not closing is related to vitamin D deficiency and not related to iron deficiency. If iron supplementation has been ongoing for half a year and the anemia condition still persists, it is recommended to further investigate the cause of the anemia and not simply explain it as iron deficiency anemia.
