Factor VIII is a crucial protein in the blood that helps with clotting. It plays a key role in the process of stopping bleeding by working with other proteins to form a stable clot. When a person has a deficiency or dysfunction of Factor VIII, it can lead to a bleeding disorder known as Hemophilia A, which makes it difficult for the blood to clot properly. People with Hemophilia A may experience prolonged bleeding after injuries or surgeries, and they may also have spontaneous bleeding episodes. Treatment often involves infusions of Factor VIII concentrates to help manage and prevent bleeding. Understanding Factor VIII is essential for those affected by this condition and their caregivers.
