Hi, Welcome to HCM, I am Dr. Das.
You tlod that your mother is taking medicine. I dont know any medicine which can increase the Hb level from 31. Your mother needs to be admitted immediately in hospital, get blood transfusion
which will improve the condition. And after reaching a steady level of hemoglobin
, medication can be started. and after 14 days of blood transfusion or before starting transfusion, Bone marrow
study is essential to categorize this anaemia
. So, dont waste time.
