Bleeding conditions are generally caused by a malfunctioning blood-clotting process. People with bleeding conditions can bleed for longer than normal. In addition, some people with bleeding conditions may experience sudden bleeding into joints, muscles, or other parts of the body.
Bleeding conditions include haemophilia A, haemophilia B, von Willebrand disease (VWD), and other rare conditions.
The most common types of haemophilia are known as haemophilia A and haemophilia B. Haemophilia A is more common than haemophilia B. In people with these 2 types of haemophilia, clotting factors are insufficient, which can lead to bleeding longer than normal.
VWD is the most common bleeding condition. It often goes undiagnosed because bleeding symptoms tend to be mild.
