Sickle Cell Disease

Medically reviewed by Last updated on Apr 2, 2024.

What is sickle cell disease (SCD)?

SCD causes your RBCs to be sickle (crescent) shaped. The sickle shape is caused by abnormal hemoglobin in the RBC. Hemoglobin carries oxygen to all tissues in your body. Sickle-shaped RBCs can get stuck inside blood vessels. This can stop or slow blood flow, and prevent oxygen from getting to tissues. When this happens, it is called a sickle cell crisis. SCD also causes RBCs break apart and die faster than healthy RBCs. This causes low red blood cell levels (anemia).

SCD is passed from parents to a child. A child is given 2 abnormal genes for hemoglobin, 1 from each parent.
