What is sickle cell anemia?

Explanation:
Sickle cell anemia is a genetic blood disorder where red blood cells become abnormally shaped due to a faulty hemoglobin called hemoglobin S. When oxygen levels drop, this hemoglobin polymerizes and the red blood cells deform into a rigid, crescent shape. These misshapen cells don’t flow as easily through small vessels and don’t carry oxygen to tissues as effectively, leading to fatigue from anemia and potential pain from blockages in the blood vessels. The core issue is the red blood cells’ altered shape and reduced oxygen-carrying capacity, not problems with white blood cells, platelets, or the skin.
