Step-by-step explanation:
The most common cause of death in adult sickle cell anemia patients is organ damage and complications resulting from the blockage of blood vessels by the sickle-shaped red blood cells. The abnormally shaped cells can get stuck in narrow capillaries, preventing oxygen from reaching certain organs and tissues. This can lead to serious problems such as stroke, heart failure, acute chest syndrome, and organ failure.
