What is Sickle Cell Disease?
Sickle cell anemia is a genetic disease that affects hemoglobin, the oxygen transport molecule in the blood. The disease gets its name from the shape of the red blood cells under low oxygen conditions. Some red blood cells become sickle-shaped and these elongated cells get stuck in small blood vessels so that parts of the body don't get the oxygen they need
The Role of Red Blood Cells in Anemia
Watch this video to learn about how the body makes red blood cells, which contain hemoglobin and carry oxygen throughout the body. Anemia occurs when there are too few red blood cells or not enough hemoglobin.
The Problem With Sickled Cells
In sickle cell anemia, the hemoglobin is abnormal, causing the red blood cells to be rigid and shaped like a C or sickle, the shape from which the disease takes its name. This video shows how the shape of sickle cells causes them to get stuck in vessles and block the flow of blood, which can result in pain and infections
