Hi, Welcome to Health care magic forum.
As you describe, she must be anemic since long. Lucky she is not facing any problem with it.
I advise you to consult a physician for diagnosis and treatment, because the level is very low.
The worms in the intestine may be the one of the causes, the other cause may be the less intake of nutrient foods.
She may need to have injection of iron, for treatment of
anemia.
So i advise you to consult a surgeon for diagnosis and treatment.
Let her take more of green leafy vegetables, pulses, sprouts, and protein rich foods, to have a early recovery.
Wishing for a quick and complete recovery. Thank you.
