HI, I understand your concern. Your wife is just completing her 3 months after this stage vomiting usually stops.Possibly,she would the eat well/ digest food & regain her health back. Still she should get examined & investigated for finding cause of anemia. The treatment plan would depend on the results of investigations ( Typing of anemia, sickle cells , stool & urine examination to exclude/ diagnose infection etc.) - Till then let her have high protein diet with iron rich food ( all dark colored food articles like.. dark green vegetables, beet root, jaggary & monkey nuts, malt, honey,), fruits & salads, milk & milk products , folic acid ( cauliflower, sprouted wheat), Vitamin C ( lemon ),vitamin B12 pills . 8.2 gm% is sever anemia so treatment of causative factor & iron, protein & vitamin supplements should be tried for one month Otherwise she should start taking oral/ injectableiron preparations OR blood transfusion as per treating dictor s advise. Thanks,
