📋Overview
Sickle cell crisis is an acute complication of sickle cell disease, a genetic blood disorder characterized by abnormal hemoglobin (HbS) that causes red blood cells to become rigid and sickle-shaped. These sickled cells can block blood flow, leading to episodes of severe pain and organ damage. The term 'sickle cell crisis' refers primarily to vaso-occlusive crises, the most common type of acute complication in sickle cell disease.
