Inflammatory diseases in general also cause hemoglobin levels to drop, as noted in the Journal of Clinical Oncology. Cirrhosis and other chronic liver diseases cause anemia because they put patients at risk for gastrointestinal bleeding, according to the World Journal of Gastroenterology. This bleeding happens because the blood in the damaged liver no longer coagulates properly. Hepatitis may also lead to aplastic anemia, in which the bone marrow no longer produces enough red blood cells. Liver diseases can also cause the spleen to enlarge, as stared by WebMD.

The signs and symptoms of thalassemia usually present when the patient is very young.
