[|Human|] I have a brother, 63 years of age, every time he goes to the doctor they tell him he has internal bleeding (loss of blood) and low B12. He said he never sees his blood loss. His feet and legs hurt all the time, he has high blood pressure but has allergic reactions to all medicine prescribed for high blood pressure. He acquired eye infections from the last medication he took for high blood pressure, it has been almost a year since he stopped taking the medication but he still has eye infections? The V.A. hospital can never identify why he is losing blood and how? What could it be?
[|AI|]  Hi, Welcome to Chat Doctor forum.  Your brother was told that he is loosing blood, and the doctors don't know how he is loosing blood. He has low B12.  It appears the has low blood, means anemia, may be due to the deficiency of the B12.  Ask him take more of green leafy vegetables, pulses, sprouts, and protein rich foods to develop the blood, general health and provide B12.  I advise you to consult a physician for diagnosis and treatment.  Wishing for a quick and complete recovery. Thank you.
