Hemophilia A
Hemophilia A
Hemophilia A (pronounced: hee-muh-FIL-ee-uh A), also known as Factor VIII deficiency or classic hemophilia, is a genetic disorder caused by missing or defective Factor VIII, a clotting protein.
Etymology
The term "Hemophilia" is derived from the Greek words haima (blood) and philia (love), indicating a "love of blood," or more accurately, a "love of bleeding." The "A" in Hemophilia A refers to the specific clotting factor that is deficient or missing in individuals with this condition.
Symptoms
People with Hemophilia A may bleed for a longer time than others after an injury or surgery. In severe cases, they may start bleeding for no apparent reason. This spontaneous bleeding can occur into joints and muscles, causing pain and swelling.
Diagnosis
Hemophilia A is diagnosed through a blood test that measures the level of factor VIII activity. If the factor VIII activity level is significantly lower than normal, a diagnosis of Hemophilia A is made.
Treatment
Treatment for Hemophilia A involves replacing the missing factor VIII in the blood through infusions. This can be done at a hospital or at home. The frequency of treatment depends on the severity of the Hemophilia A.
