When you have the rare but treatable disorder known as aplastic anemia, your marrow -- the spongy substance inside your bones -- stops making new blood cells. Sometimes it stops making just one type, but more often you become low on all three: red and white cells, and platelets.
It can develop slowly or come on suddenly. If your blood count gets low enough, it can be life-threatening.
Blood disorders can affect any of the three main components of blood:
Red blood cells, which carry oxygen to the body's tissues
White blood cells, which fight infections
Platelets, which help blood to clot
Blood disorders can also affect the liquid portion of blood, called plasma.
Treatments and prognosis for blood diseases vary, depending on the blood condition and its severity.
Anyone can get aplastic anemia, but it's more likely to happen to people in their late teens and early 20s, and the elderly. Males and females have about an equal chance of getting it. It is more common in developing countries.
There are two different types:
acquired aplastic anemia
inherited aplastic anemia
Doctors will check to determine which you have.
Inherited aplastic anemia is causes by gene defects, and is most common in children and young adults. If you have this type, there is a higher chance of developing leukemia and other cancers, so see a specialist regularly.
Acquired aplastic anemia is more common in adults. Researchers believe something triggers problems in the immune system. The possibilities include:
