Causes and Symptoms of Hemophilia
What Is Hemophilia?
Hemophilia is an inherited bleeding disorder in which a person lacks or has low levels of certain proteins called “clotting factors” and the blood doesn’t clot properly as a result. This leads to excessive bleeding. There are 13 types of clotting factors, and these work with platelets to help the blood clot. Platelets are small blood cells that form in your bone marrow. According to the World Federation of Hemophilia (WFH), about one in 10,000 people are born with this disease.
People with hemophilia bleed easily, and the blood takes a longer time to clot. People with hemophilia can experience spontaneous or internal bleeding and often have painful, swollen joints due to bleeding into the joints. This rare but serious condition can have life-threatening complications.
The three forms of hemophilia are hemophilia A, B, and C.
Hemophilia A is the most common type of hemophilia, and it’s caused by a deficiency in factor VIII. According to the National Heart, Lung, and Blood Institute (NHLBI), eight out of 10 people with hemophilia have hemophilia A.
