Factor VII Deficiency

Factor VII deficiency is a rare inherited bleeding disorder in which the body makes too little of clotting factor VII. Factor VII starts the chain of steps that forms a clot.

Women with the condition can have heavy periods, bleeding between periods, bleeding after surgery, and bleeding after birth. A clotting disorder is a common cause of heavy flow in young women. In a review of 2,770 adolescents with heavy periods, clotting disorders accounted for about 19 percent of cases.1

Clotting studies also belong in a workup for recurrent pregnancy loss. Evidence tying factor VII deficiency itself to miscarriage is thin.
