Thalassemias are inherited blood disorders. If you have one, your body makes fewer healthy red blood cells and less hemoglobin. Hemoglobin is a protein that carries oxygen to the body. That leads to anemia. Thalassemias occur most often among people of Italian, Greek, Middle Eastern, Southern Asian, and African descent.
