Haemophilia A is a genetic disorder that affects the body's ability to clot blood. It is caused by a deficiency in factor VIII, a protein that is necessary for blood clotting. This condition is typically inherited and affects males more often than females.
Symptoms[edit]
The primary symptom of Haemophilia A is prolonged bleeding. This can occur after an injury or surgery, and in severe cases, spontaneous bleeding can occur. Other symptoms can include:
- Bleeding into joints and muscles
- Blood in urine or stool
- Nosebleeds
- Bruising
- Bleeding gums
Causes[edit]
Haemophilia A is caused by a mutation in the F8 gene, which provides instructions for making factor VIII. This mutation can be inherited from a parent, or it can occur spontaneously.
Diagnosis[edit]
Diagnosis of Haemophilia A typically involves blood tests to measure the level of factor VIII in the blood. Genetic testing may also be used to identify the specific mutation causing the condition.
Treatment[edit]
Treatment for Haemophilia A typically involves replacing the missing factor VIII through infusions. Other treatments can include:
