Vitamin K plays an important role in coagulation, better known as blood clotting. Clotting is a process that helps prevent excessive bleeding both inside and outside the body. When the blood doesn't clot, excessive or prolonged bleeding can occur. It can also lead to spontaneous or sudden bleeding in the muscles, joints, or other parts of the body. Vitamin K deficiency is much more common in infants. Hence, continuous bleeding from an injured part of the body is due to a deficiency of vitamin K.
