Bernard-Soulier syndrome, also known as hemorrhagiparous thrombocytic dystrophy, is a rare disorder that prevents a person from being able to stop bleeding after an injury or surgery. A portion of our blood is made up of platelets, which are cells that help blood to clot and therefore stops bleeding. While people affected by Benard-Soulier syndrome have large platelets, they do not have enough. This means that something as small as a paper cut will not stop bleeding for hours. Other symptoms of people affected with Bernard-Soulier syndrome are bleeding gums (the area around your teeth), easy bruising, and heavy menstrual periods. Talk with your doctor to find the best treatment if you or a loved one has been diagnosed with Bernard-Soulier syndrome.
