Welcome to Bleeding Disorders Basics!

Maybe you’ve just been diagnosed, or maybe your baby has just been diagnosed with a bleeding disorder. Maybe you were diagnosed at birth, and you’ve lived with a bleeding disorder your entire life. Maybe you are somewhere in between. No matter where you fall along that spectrum, knowledge is power. For more information on the types of bleeding disorders, click here.

If you think you might have a bleeding disorder, you’ll want to consult an expert. Hematologists are experts in bleeding disorders. A hematologist can diagnose your bleeding disorder, provide guidance for managing your bleeding disorder, and prescribe the treatments and therapies to ensure your best possible outcome.

Bleeding disorders are complex and often require collaboration with other health professionals, such as nurses, physical therapists, geneticists, and social workers. To facilitate comprehensive care for patients with bleeding disorders, the United States federal government provides some of the funds that support hemophilia treatment centers (HTCs) across the country. HTCs help coordinate your care with other medical experts to treat all aspects of your bleeding disorder. Please visit to find an HTC near you.

Where Do You Start?

Knowledge is power: Learn about your bleeding disorder. There is a wealth of information available online, and your hematologist and other HTC staff can teach you about your diagnosis, the symptoms, how to recognize a bleed early, and what to do when you suspect you are having a bleed or when an injury occurs. You will also find a lot of information on this website [and in the HFA Learning Center, our e-learning program**insert later]. Some of the areas we recommend include the following:
