Having blood clots in menstruation does not necessarily indicate that there is bruising in the body, but rather that the menstrual bleeding is heavy or fast, and if there is a lot of it every time you menstruate, it is recommended that you seek medical attention in a timely manner. Menstruation is the cyclical shedding and bleeding of a woman’s uterine lining under the action of estrogen and progesterone. The components of menstruation include blood, fragments of the uterine lining, cervical mucus, and vaginal shedding epithelial cells. Since menstrual blood contains fibrinolytic enzymes from the endometrium, menstrual blood is usually non-clotting, but if the menstrual bleeding is heavy or fast, blood clots may appear rather than being caused by stagnant blood in the body. If blood clots appear only occasionally in menstruation, you can continue to observe; if the amount of menstruation is heavy and a large number of blood clots appear every time, it may cause anemia, etc. It is recommended to go to the hospital in time to improve the relevant examination and exclude related diseases.
