Why can sickle blood cells cause so many problems?

Sickle blood cells can cause numerous health problems due to their abnormal crescent shape, which makes them rigid and sticky. This leads to blockages in small blood vessels, restricting blood flow and oxygen delivery to tissues, causing pain and potential organ damage. Additionally, these cells have a shorter lifespan than normal red blood cells, leading to anemia and further complications. The resulting inflammation and vaso-occlusion can trigger severe episodes known as sickle cell crises, exacerbating health risks.
