Apparently A third of all non pregnant women of reproductive age are deficient in iron and probably anaemic. Iron deficiency is caused by a number of different things but it often has significant and noticeable effects such as reduced physical and work capacity. Furthermore, if pregnancy occurs iron deficiency increases the risk of low birth weight babies and even complications during delivery.
There is evidence suggesting that brain iron deficiency in women may also disrupt both metabolic processes leading to changes in cognitive and behavioural functioning. Women of reproductive age are among those vulnerable to iron deficiency and may be at risk of altered cognitive functioning as a consequence of iron deficiency. Iron deficiency has also been related to depression and anxiety. More research is needed to fully understand the profound effect that anaemia has on psychological functioning. If you suspect you may be anaemic you should consult your doctor.
