Haemophilia A

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

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

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

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

Treatment for Haemophilia A typically involves replacing the missing factor VIII through infusions. Other treatments can include:

• Antifibrinolytic medicines
• Physical therapy
• Pain medicines
