Factor 2: platelet factor. Platelets play an important and complex role in hemostasis. When the quantity or quality of platelets is abnormal, it is often easy to cause skin and mucous membrane hemorrhage. In severe cases, there may be visceral hemorrhage, such as gastrointestinal tract, urinary tract, respiratory tract, uterus and even cerebral hemorrhage.
