**__Hemophilia__**

=
 Hemophilia is a rare genitic disorder that can be traced all the way back to medieval eras. Hemophilia involves excessive bleeding due to lack of or minimal clotting. Clotting is the process of your blood turning from a liquid to a solid to stop the bleeding. With hemophilia you still have all your chomosomes, but the twenty-third chromosome is affected making it a sex disorder. The X chromosome is the carrier for disorder, and although it is more common in males, both genders can be carriers of the disorder. Since hemophilia is a recessive trait, females without hemophilia can still be carriers and have kids that develope hemophilia. There are no outside risk factors that can increase the risk of hemophilia. The only way for a baby to be born with the disorder is if the mother is a carrier. There are three types of hemophilia, type A, B, and C. Type A and B are most common in caucasian males, while type C is most common in males from the Jewish descent. =====

Many people with hemophilia die before they reach adulthood, but with proper treatment they can have a normal life expectancy. One type of treatment would be to get regular clotting factor replacements. Those with hemophilia have to avoid injury at all costs, for there is a possibility of exsanguination. They also have to be careful with medications such as Advil that can cause bleeding in the stomach. =====
