Symptoms of hemophilia range from increased bleeding after trauma, injury, or surgery to sudden bleeding with no apparent cause. There are two types of hemophilia:
Hemophilia A -- also called classic hemophilia -- is most common and occurs in about 80% of people with hemophilia.
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:
