What causes cells to sickle?

Sickle cell is an inherited disease caused by a defect in a gene. A person will be born with sickle cell disease only if two genes are inherited—one from the mother and one from the father. A person who inherits just one gene is healthy and said to be a “carrier” of the disease.

Why are sickle shaped cells Bad?

The red blood cells become fragile and shaped like crescents or sickles. The abnormal cells deliver less oxygen to the body’s tissues. They can also easily get stuck in small blood vessels and break into pieces.

Why does sickle cell prevent malaria?

    • What you should know about sickle cell disease?

    Anemia,which is caused by a lack of healthy red blood cells.

  • Pain crisis,or sickle crisis,occurs when blood flow is blocked to an area because the sickled cells have become stuck in the blood vessel.
  • Acute chest syndrome occurs when sickled cells block the flow of oxygen in the tiny vessels in the lungs.
