Dear friend, welcome to HCM.
if your dioctor feels it is anaemia
due to iron deficiency
, injectable iron is used to treat it early .
if, Hb was 4gm % , she should also require blood.
need details of the report. many causes.
LFT(liver function tests) and many blood, stool and urine tests are needed to evaluate anaemia.
your doc is the best judge.
or else send ALL the reports done.
take care and keep me posted.
