Haemophilia A is a genetic disorder that affects the blood's ability to clot properly. It is caused by a deficiency of factor VIII, a protein essential for blood coagulation. Individuals with this condition may experience prolonged bleeding after injuries, surgeries, or even spontaneously without any apparent cause. This condition is inherited in an X-linked recessive pattern, meaning it primarily affects males, while females can be carriers. Treatment often involves regular infusions of factor VIII concentrates to help manage bleeding episodes and prevent complications. Early diagnosis and proper management are crucial for improving the quality of life for those affected.
