Hemophilia is a genetic disorder that affects your blood’s ability to clot. Hemophilia sufferers lack a clotting factor, meaning they have an increased risk of bruising and bleeding, both externally and internally around joints and in the brain.
There are three levels of severity to measure hemophilia.
Someone who has mild hemophilia has a clotting factor of between 5 percent and 40 percent. People with mild hemophilia are generally only likely to have a bleed after some kind of trauma, such as surgery or a severe injury. Approximately 25 percent of hemophilia patients have the mild form of the disease.
A moderate hemophilia patient will have between 1 percent and 5 percent of clotting factor in their blood. While they tend to bleed infrequently, a prolonged bleed can occur after major surgery, injury or dental treatment. Although rare, patients with moderate hemophilia can also suffer from spontaneous bleeds. About 15 percent of hemophilia sufferers have the moderate form of the disease.
Someone with severe hemophilia will have less than 1 percent of clotting factor in their blood, and will suffer from frequent bleeds — once or twice a week — and spontaneous bleeding can occur in the muscles and joints. Severe hemophilia patients can suffer from prolonged bleeding after surgery or injury, but bleeding can also happen spontaneously.
