(Sickle Cell Disease)

Sickle cell anemia – Definition

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.

(Reduced Iron in Blood)

Iron-deficiency anemia – Definition

This condition results from reduced iron stores in the blood. This happens when you do not eat enough iron to replace the iron that your body uses. Your body uses iron to produce hemoglobin. This part of red blood cells carries oxygen to tissues and muscles. Bleeding a lot can also cause anemia.

Iron makes a critical component of red blood cells.
