What Is Sickle Cell Anemia?

Sickle Cell Anemia is a serious disorder in which the body makes sickle-shaped (crescent shaped) red blood cells which blocks blood flow in the blood vessels of the limbs and organs. This can damage organs and raise the risk for infection.

Genetic Transmission

Sickle Cell Anemia is a lifelong disease that is inherited. People that are born with it have two genes for sickle hemoglobin; one from each parent. If a child inherits one sickle hemoglobin from one parent and a normal one from the other parent, the child will have the sickle cell trait. This means they have the gene but not the disease.

Life Expectancy & Treatments

Someone with Sickle Cell Anemia is expected to live up into their mid forties. This is a huge increase keeping in mind that around 1973, the life expectancy was just 14 years of age. Sickle cell anemia has no widely available cure. But treatments can help relieve painful symptoms, prevent organ damage and strokes, and it also controls the complications. Regular medical care is need for people diagnosed with Sickle Cell Anemia. There are special clinics designed for this purpose. Also, some people choose to get blood and marrow stem cell transplants as a cure but it is quite expensive. Severe sickle cell anemia can be treated with a medicine called hydroxyurea. Mild pain often is treated with over-the-counter pain medicines, heating pads, rest, and plenty of fluids. More severe pain may need to be treated in a day clinic, emergency room, or hospital.
