Sickle Cells Description, Risk Factors, and Lifestyle

Sickle Cell- Description, Risk Factors, and Lifestyle Description Sickle cell anemia is blood disorder characterized by red blood cells assuming a sickle shape. Ordinary small changes in red blood cell shape would not adversely affect the individual. However, due primarily to the excessive shape changes in the red blood cell; complications can arise within the individual. By forming a sickle shape, the red blood cell loses a disproportionate amount of its flexibility due a hemoglobin mutation. Normally, red blood cells are very elastic. This allows them to easily and seamlessly matriculate through the capillaries of the blood system. In sickle cell disease, low oxygen tension promotes red blood cell sickling. After repeated bouts of low oxygen environments the cells fail to return to normal shape when normal oxygen tension is finally restored. This then presents complications as the red blood cells can not matriculate through the capillaries. Due to this mutation complications arise the ultimately shorten the individuals lifespan. For example, as o f 2008, the life expectancy of an individual infected with sickle cell anemia is roughly between 60-65 years of age. This is in stark contrast to an ordinary human being who is expected to live roughly 80 years. Various complications can occur that often shorten the lifespan of those who carry the gene. Complications include vaso-occlusive crisis which is caused by red blood cells restricting blood flow through the capillariesShow MoreRelatedAnemia and Disorders Blood Tests1710 Words   |  7 PagesLethargy 1.
