Hemophilia refers to a group of inherited disorders that cause abnormal bleeding. The bleeding occurs because part of the blood -- called plasma -- has too little of a protein that helps blood clot.
Symptoms of hemophilia range from increased bleeding after trauma, injury, or surgery to sudden bleeding with no apparent cause. There are two types of hemophilia:
Hemophilia A -- also called classic hemophilia -- is most common and occurs in about 80% of people with hemophilia.
Call 911 for immediate emergency medical help if you have any of these symptoms:
Lengthy, uncontrollable bleeding -- either heavy or oozing in nature -- particularly after injury, immunizations or surgical or dental procedures. Seek emergency medical help for any heavy or uncontrolled bleeding.
Any signs of internal bleeding, such as a change in consciousness, alertness, or memory or difficulty breathing (note that these symptoms may also be signs of other medical problems unrelated to hemophilia).
Call your doctor if you notice any of these symptoms:
Any episode of bleeding unrelated to a particular injury or event
Pain, swelling, warmth, or redness in a joint or muscle
Also call your doctor if you are parents who have a family history of hemophilia and are expecting a baby.
