What hemophilia is:
Hemophilia is an inherited disease that affects a person’s blood. There are different types of hemophilia: Hemophilia A, hemophilia B and hemophilia C, but all the types of hemophilia affect the blood (Mayo Clinic Staff, Hemophilia). The proteins that cause the blood to clot are called Factor VIII, Factor IX, and XI (Mayo Clinic Staff, Hemophilia). A person with hemophilia doesn’t have or isn’t able to make these proteins that is used in the body for blood-clotting. This means if a person with hemophilia is cut, even a small cut, it will continue to bleed and will not be able to clot and stop. It can be a very dangerous disease because of this and people with hemophilia are more likely to die from blood loss.
Types and differences of Hemophilia:
Hemophilia has three different types, A, B, and C. Hemophilia A is the number one type, which means it’s the most common, Hemophilia B is the second most common, and then Hemophilia C is the least common and can be very severe at times (Mayo Clinic Staff, Hemophilia). Each one is caused by lacking a different clotting factor. Hemophilia A is missing factor VIII, Hemophilia …show more content…
Hemophilia has several symptoms but the main symptom is prolonged bleeding which can have serious effects (Mayo Clinic Staff, Hemophilia). Some symptoms could be bleeding into the joints, which causes swelling and pain in the joints, and extreme bruising, where blood builds up underneath the skin and is caused by the blood fill up the area underneath the skin (CDC, Hemophilia). Other symptoms could include nosebleeds for no reason, blood in a person urine which could be a sign of bleeding from internal organs, even bleeding in the brain is possible to occur (NIH, Explore
