The causes of frequent bruising in women include the following: firstly, the bruising is caused by the abnormal coagulation function of the body, mostly due to the lack of certain coagulation factors in the coagulation system of the body, or the excessive inactivation of platelets due to hypersplenism, which can lead to abnormal bleeding, resulting in blood spilling out of the veins and causing bruising. Secondly, the bruising is caused by the dysfunction of the body’s immune system, mostly due to irregular life, long-term late night or stressful work, which causes inflammation and bleeding of the blood vessel wall and inflammatory exudation, leading to bruising. It is necessary to go to the hematology department of the hospital to do blood routine and coagulation system examination to clarify, and at the same time, we should pay attention to rest to avoid local bleeding and bruising caused by bruises or abrasions.
