dear friend, welcome to HCM.
iron deficiency anaemia
is an extremely common condition and not that serious unless neglected and anaemia results in heart failure
it is due to nutritional deficiency
of iron or blood loss.
do you have excess menstrual bleed or other bleeds? black stools?
have they ruled out occult GI bleed by stool occult blood test?
do you have swollen feet? breathless?
pl. get detailed evaluation done and take appropriate treatment under medical supervision. it is easily treatable usually.
take care and keep me posted.
