Sickle Cell Anemia INTRODUCTION “Sickle cell anemia is a disease passed down through families in which red blood cells form an abnormal crescent shape. It is caused by an abnormal type of hemoglobin called hemoglobin S” (Sickle cell anemia, 2011). Hemoglobin is an iron-rich protein and an important component of blood.
This paper briefly analyses various characteristics of Sickle cell anemia. DESCRIPTIVE STATISTICS Anemia is a condition in which the number of red cells in blood decreases beyond certain limits. It can occur because of lack of hemoglobin and defective functioning of hemoglobin. Sickle cells contain sickle hemoglobin or hemoglobin S which is causing Sickle cell anemia. The changes in the shape of red blood cells are referred as sickling in medical terms. Sickle shaped means the shaping of red blood cells in the form of a crescent. Normally blood cells are disc shaped and therefore it can move quickly through the blood. However, when it attains the shape of a crescent, mobility of these cells would be decreased. (Kids health: Sickle Cell Anemia, 2011) Sickling can affect the normal functioning of the cells in different ways. It can reduce the flexibility of the cells and thereby various complications can occur to the patient. Life expectancy of the Sickle cell anemia patients has found to be comparatively lower to that of the normal people. Sickle cell anemia is usually appearing at the childhood itself. In areas where malaria is common, Sickle cell anemia found to be more common. In other words, a connection between Sickle cell anemia and malaria cannot be ruled out. ...
