I have also consult hemotologist And tested all report was normal. please give me some advice. [/INST] Dear Friend, greeting from Chat Doctor. I understand your problems. You need to go for blood transfusion since your HBO is very, very low . Plus iron injections or oral supplements. Take more of iron rich foodstuff. Jagger, nuts, meat, green leafy vegetables, fruits may be with citrus fruits. You need to find out the cause for low HBO. Vitamin deficiency/ pernicious anemia / hook worm infestation / nutritional deficiency. Finding out the cause is very important. Thank you for contacting us and do contact us for more information . THANK YOU . </s>
