Thalassemia is an inherited blood disorder. It is only transferred from parents to offspring. It is one of the most common genetic disorders worldwide. Hemoglobin is an iron-rich protein in red blood cells, carrying oxygen in all parts of the body. People with Thalassemia can have mild to severe anemia. Thalassemia occurs in high frequency in a broad belt extending from the Mediterranean basin, through the Middle East, Indian subcontinent, Burma and southeast Asia.
Human beings have two beta and four alpha genes which are required to make protein chains. In beta thalassemia minor, the person has one abnormal beta gene which doesn’t affect their health, while in beta thalassemia major, both the beta genes are abnormal. Beta thalassemia major is a fatal condition inherited by the offspring if both the parents have beta thalassemia minor. The patient of beta thalassemia major becomes dependant on blood transfusions, suffering from severe anemia, jaundice, spleen and liver enlargement and malfunctioning and bone problems.

Regular donors of blood have a lesser risk of heart diseases and heart attacks. They are kept up to date with their health status due to the medical checkups they go through before every donation, thus they can always take preventive action for any disease that emerges in their reports.
