it s already great realizing the hemoglobin
levels are falling. worthwhile investigating the type of anemia
(inadequate blood quantities), characterizing it to know whether it is due to a bone marrow
problem or other. This shall help in detecting exactly the cause of the low hemoglobin and therefore treating it.
Remember certain drugs, infectious or tumours can cause low hemoglobin levels. and if these conditions are detected early enough, appropriate, cheap and surer treatment options could be offered that are more effective.
Consulting a hematologist
for a proper evaluation is worthwhile.
Thanks and fast recovery,
