My Aunt age is 33 year. She has a very low hemoglobin (around 5.7) for a year and it is not increasing. Her MC cycle is Normal. Heamotology Report, BioChemistry Report , Serology Report and Urine Analysis Report were normal except Heamoglobin count. On biweekly basis, blood is injected to body externally and that increases her blood counts and Hemoglobin. Given Solution provides her temporary relief. Can you explain what kind of doctor we have to consult to identify the root cause of problem.
