The two main groups of thalassemia are called alpha and beta. There are four types of alpha thalassemia and three types of beta thalassemia. Alpha thalassemia genes are found in Southeast Asians, blacks, and people originally from the Middle East. The disease affects the red blood cells in two ways. First the body cannot make enough cells with normal hemoglobin.
In iron deficiency anemia, the red cells appear abnormal and are unusually small (microcytic) and pale (hypochromic). The pallor of the red cells reflects their low hemoglobin content. The prevalence of iron deficiency anemia spans all ages and races. In children, iron deficiency causes developmental delays, behavioral disturbances, failure to thrive (grow) and increased infections. Iron deficiency is a major problem in developed countries such as the US, Canada, the UK and across Europe.
