The treatment of choice for hemochromatosis is phlebotomy, which involves the regular removal of blood to reduce iron levels in the body. This method is more effective and safer for most patients compared to chelating agents, which are reserved for cases where phlebotomy is not feasible or when there is severe anemia or hypoproteinemia.
