Hemophilia
Hemophilia is a genetic disorder that affects the blood's ability to clot. It occurs most commonly in males and can lead to excessive bleeding. People with hemophilia may manage their condition with regular monitoring and appropriate treatments.
Hematology- What exactly is hemophilia and how does it affect my blood?MedlinePlusMay 2026
Hemophilia is a rare bleeding disorder where your blood doesn't clot properly because it's missing or low in clotting proteins called factors. This means you can bleed too much after an injury or even bleed inside your body without getting hurt.
- How do low levels of clotting factors cause bleeding problems in me?MedlinePlusMay 2026
Clotting factors are proteins that work together to form clots and stop bleeding. When you don't have enough of these factors, your blood can't form clots quickly enough, so bleeding lasts longer and can happen in unexpected places.
- Is there a difference between hemophilia A and B? How does that matter for me?MedlinePlusMay 2026
Hemophilia A is caused by low factor VIII, while hemophilia B is caused by low factor IX. The type matters because each one requires different replacement factor treatment, so your doctor needs to know which type you have.
- Why might I bleed inside my body without an injury?MedlinePlusMay 2026
Without enough clotting factors, your blood vessels can leak or small tears inside your body don't seal up properly, causing bleeding in joints, muscles, and organs even without an obvious injury.
- What are the chances of passing hemophilia to my children?MedlinePlusMay 2026
Hemophilia is inherited through genes, so there's a chance of passing it to your children. The exact risk depends on your type of hemophilia and your family's genetics—your doctor can explain your specific situation.
