Easy thrombosis is a state of hypercoagulability of the blood due to an inherited or acquired deficiency of the anticoagulant proteins coagulation factors and fibrinolytic proteins. If it is due to congenital genetic causes, lifelong anticoagulation is usually required. Some of the susceptibility to thrombosis is caused by secondary factors such as infection and trauma. If these causes can be effectively controlled and cured, then the condition of eosinophilia can be well controlled and lifelong anticoagulation is usually not required. However, if it is due to protein C and protein S deficiency, anticardiolipin antibody syndrome and other congenital factors, it is usually very difficult to completely cure easy thrombosis. Patients need to be closely monitored and treated with long-term anticoagulation. If thrombophilia occurs, consult a doctor promptly to clarify the cause and follow the doctor’s instructions to determine the treatment plan.
