Sickle cell disease is an inherited condition that's often characterized by oddly shaped red blood cells. Their crescent shape, caused by an abnormal type of hemoglobin, can hinder these cells as they pass through small blood vessels.

This lack of blood flow often damages bodily organs and tissues.

Early diagnosis and preventive measures -- including folic acid supplements and vaccination against a contributing bacterium -- can help treat the condition, the Sickle Cell Disease Association of America says.

While blood transfusions can help prevent complications like stroke, transfusions can also lead to iron buildup in the blood, which may require its own treatment.
