Sickle cell disease is a genetic blood disorder where red blood cells become stiff, sticky, and are shaped like a crescent instead of round. This unusual shape makes it harder for the cells to move through blood vessels, often causing painful blockages, organ damage, and other complications. These sickled cells also die faster than normal ones, leading to a constant shortage of red blood cells, called anemia, which causes tiredness and weakness.  Although there is no universal cure, treatments like medication, blood transfusions, and healthy habits can help manage symptoms and improve quality of life.
