What is SCD?

SCD is an inherited blood disorder that results in chronic health problems. People with SCD have abnormal hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the rest of the body. Abnormal, or sickle-shaped, hemoglobin cannot deliver enough oxygen to the rest of the body. This causes individuals with SCD to experience episodes of pain. Over time, the lack of oxygen damages the organs, especially the spleen, brain, lungs and kidneys. SCD also causes anemia, or a low number of red blood cells. There are several types of SCD, including hemoglobin SS, hemoglobin SC and hemoglobin S-beta thalassemia. The most common type of SCD is hemoglobin SS. The different types of SCD have some unique symptoms and some in common. It is important to find out which type of SCD your child has and talk with your doctor about signs, symptoms and treatment specific to that condition.
