Answer: people with hemophilia constantly need to receive injections of the protein because, hemophilia can causes internal bleeding in severe cases, which can result in the damage of organs and joint. This is because people who have hemophilia lack a specific protein (which is called a clotting factor) that enables blood to clot.
Step-by-step explanation:
Hemophilia is a hereditary bleeding disorder which is characterized by either decreased, defective or absent production of blood clotting proteins.
The treatments needed will depend on the type of hemophilia and the severity of hemophilia. For example, if you have mild hemophilia (that is relevant clotting factor activity is greater than 5%, but less than normal), you may need treatment only when you are in preparation for a surgery or when you have an injury. However, if you have severe hemophilia that bleed frequently, you may need regular (several times in a month) to help prevent bleeding and help protect your joints from deformity and disability.
