Sickle cell anemia is a disorder of the blood passed down from parents to children. This problem is related to red blood cells. The normal blood cells are round and smooth and are able to move in narrow blood vessels without any difficulty.
The sickle cells are hard and have a curved edge. These cells are unable to pass through narrow blood vessels due to which certain tissues and organs may not receive blood supply and oxygen.
The life of sickle cells is short and the body is not able to produce new red blood cells at the rate at which they die. This gives rise to shortage of red blood cells and hence anemia.
Sickle cell anemia is caused by a recessive allele. The type of hemoglobin a person makes in the red blood cell depends on the hemoglobin gene that is inherited from parents. A person that receives the defective gene one number each from both the parents inherits the disease. A person that receives one defective gene from one parent and a healthy gene from the other parent remains healthy but he can pass on the disease to the next generation, hence he becomes a carrier of the disease. If two parents are carriers of the disease, there is a 25 percent chance of their child developing the disease and 50 percent chance of the child being carrier of the disease. In United States this disease is prevalent mostly in African Americans.
Women with sickle cell disease can have a healthy pregnancy and they have to be careful to avoid problems. The disease may become severe and the frequency pain episodes may increase. With prenatal care and careful monitoring they can have healthy pregnancy. During the second month of pregnancy, a pregnant woman can undergo test to find out whether the unborn baby will have sickle cell disease, sickle cell trait or normal.
