Normal red blood cells are smooth and round. They move easily through blood vessels to carry oxygen to all parts of the body.In sickle cell anemia, the red blood cells become hard, sticky, and shaped like sickles or crescents. The cells tend to stick in the vessels and block blood flow.This can cause damage, pain, and anemia. Anemia is a shortage of red blood cells in your blood. In sickle cell anemia, the shortage occurs because cells do not last very long.Your body cannot make enough new cells to keep up.
Sickle cell anemia is a serious disease with no universal cure.

People with sickle cell anemia inherit two genes, one from each parent that are variant (different from normal).

Hemoglobin is the part of the red blood cell that carries the oxygen to all parts of the body.
