The Main Types of Anemia
Anemia occurs when there is a low number of red blood cells (RBCs) circulating in the body and is one of the most common blood disorders to affect the general population. Currently, anemia affects more than 3 million people ion the country, and more than 400 types of anemia that have been identified and divided into three main groups according to their cause. They are anemia caused by the destruction of RBCs, anemia caused by decreased production or production of faulty red blood cells, and anemia caused by blood loss. The main kinds of anemia across these categories are discussed herein. Sickle Cell Anemia Sickle cell anemia causes the body to produce sickle or C-shaped RBCs as opposed to the normal, iron and hemoglobin-rich RBCs which are disk-shaped and are able to move about easily in the blood vessels. Sickle cells don’t last very long and die 10–20 days after they are formed. Since the body cannot reproduce RBCs quickly enough to replace the ones that are dying, it ends up causing anemia. Treatment includes intravenous fluids, pain relief, and oxygen therapy, blood transfusions, folic acid supplements, and antibiotics. Vitamin Deficiency Anemia Vitamin deficiency anemias or pernicious anemias are when the body cannot produce enough healthy RBCs because it does not have enough vitamin B12.
