If there is a blood clot in the vagina, it is often due to a break in the vaginal mucosa, or localized bleeding caused by trauma. When there is bleeding in the body, the clotting mechanism is activated and the blood coagulates and forms a clot. This clot is often localized to the wound, causing the bleeding to stop. If the wound is large, active bleeding tends to continue. It is recommended to give a clinical gynecological examination to understand the site of bleeding and to stop the bleeding with sutures if necessary for the purpose of healing. In addition, in the case of mucosal damage caused by a blood clot in the vagina, it is clinically important to find the cause and if it is caused by trauma, suturing is sufficient. If it is caused by inflammation, anti-inflammatory treatment is recommended.
