Hi and thanks for the query, Low blood pressure and low hemoglobin levels require a proper evaluation, most importantly by hematologist. Treating without knowing the exact cause might not be very useful. This could e a problem at the level of the bone marrow or other body structures. A complete blood count, thin and thick blood films to characterize the type of anemia might be helpful. Depending on these results and clinical evaluation of the hematologist, a bone marrow test called a bone marrow aspirate might be necessary. Consult your hematologist for a proper clinical evaluation. thanks and best regards., Luchuo, MD.
