Sickle cell anemia is a genetic disorder. It alters the shape of the red blood cells (RBCs). This decreases their ability to carry oxygen. It can also cause acute episodes of pain. These are called a sickle cell crisis. The body will also destroy the sickle cells. The loss of RBCs results in anemia.
The change in the ability and number of RBCs can decrease the amount of oxygen for the body.

Sickle cell disease is a genetic disorder. If you receive one defective gene from each of your parents, then you will have sickle cell disease. If you only have one defective gene, you are said to have sickle cell trait, but not sickle cell disease. Although you won’t usually have any symptoms, you can pass this gene on to your children.
