- Sickle Cell Disease (SCD) is an inherited blood disorder that affects hemoglobin, the protein found in red blood cells (RBCs) that helps carry oxygen throughout the body, changing the shape and function of the RBCs.
- A person with SCD have RBCs that change from the normal flexible, round, donut-shaped cells to hard, stiff, & sticky sickled– shape cells comparable to the shape of a crescent moon, which makes it difficult for the RBCs to flow smoothly through the veins.
- SCD largely affects the African American population. It is also identified in Asians, Indians, Greeks, Italians, and Hispanics and many racial groups.
