Sickle cell disease and pregnancy

key information

Sickle cell disease is a blood disorder passed down from parent to child. People with sickle cell disease have abnormal hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen to the body.

The abnormal hemoglobin in sickle cell disease makes the red blood cells stiff and sticky.
