means that you have a deficit of red blood cells but also of white blood cells and platelets. Aplastic

anemia is rare, affect fewer than 1,000 people each year in the United States. Idiopathic aplastic anemia is

a condition known to cause aplastic anemia, which is been linked to exposure to chemicals such as

benzene and radiation. It is also believed that some cases of aplastic anemia are inherited and that some

cases are due to a viral infection.

In aplastic anemia, “the bone marrow is described in medical terms as aplastic or hypoplastic -

meaning that it's empty, or containing very few blood cells...” Factors that can temporarily or permanently

injure bone marrow include: high-dose radiation and chemotherapy treatments, which damage healthy

cells, including stem cells in bone marrow and Secondary aplastic anemia can be a temporary side effect

of these treatments; a viral infection in some people and the use of certain drugs…such as antibiotics can

cause secondary aplastic anemia. Aplastic anemia can develop at any age, but it's more commonly

diagnosed in children and young adults. Signs and symptoms of aplastic anemia and secondary aplastic

anemia are: fatigue, weakness, shortness of breath with exertion, rapid heart rate, pale skin, frequent

infections, unexplained bruising, easy bruising, nosebleeds and bleeding gums, prolonged bleeding from

cuts, skin rash and fever. The reduction in the level of each of the three blood cell types, which can lead to

unexplained infections, is related to fewer white blood cells and unexpected bleeding (due to fewer

platelets) and fatigue. To confirm a diagnosis of aplastic anemia, a physician examines a blood sample

and determines the number of each type of blood cell circulating in the blood. To confirm a diagnosis of

aplastic anemia, the doctor will need a bone marrow biopsy. In this procedure, a doctor uses a needle to

remove a small sample of bone marrow from a large bone in the body, such as the hipbone, which is

examined under a microscope to rule out other blood-related diseases.

To treat aplastic anemia for young individuals with, a bone marrow (stem cell) transplant can be used to

replace the defective bone marrow with healthy cells. Bone marrow transplant carries many risks, so it is

not used as a treatment for middle-aged or elderly individuals. For older individuals, treatment of aplastic
