Why do blood clots appear during menstruation?

Any changes during menstruation cause anxiety in women. Almost everyone has experienced such a phenomenon as blood clots with menstruation. The reasons for this can be different - from completely harmless to serious diseases, requiring the intervention of doctors.

What happens with menstruation?

Every month, regardless of the woman's desire, her uterus prepares to take a fertilized egg. Under the influence of hormones begins to thicken the inner layer of the uterus - the endometrium. If pregnancy does not occur, the level of hormones decreases, the blood supply of the mucous membrane of the inner surface of the uterus ceases, the endometrium is rejected and withdrawn through the genital tracts to the outside. Thus, menstrual flow is a complex mixture consisting of blood, mucus, endometrial particles, vaginal cells.

Blood clots at monthly -

norm This phenomenon during menstruation does not always indicate the presence of pathology. It is possible that the monthly flow is normal, and you should not worry. As is known, these days the dying and the endometrium is dying out, which becomes loose and thick during the cycle. That is, menstrual discharge by itself is not liquid by itself, as it consists not only of blood, but also of the tissues of the inner membrane of the uterus and glandular secretions. In addition, their consistency and color change day by day.

Usually, blood clots leave immediately as soon as a woman gets out of bed after sleeping or from a chair after a long sitting. This is due to the fact that the blood in the uterus is stagnant in a recumbent or sitting position and begins to coagulate, forming clots. As soon as a woman gets up, they go outside, and this is not a deviation from the norm.

In order for menstrual flow easier to exit, special enzymes-anticoagulants inhibit blood clotting. If the bleeding is abundant, the enzymes can not cope with their task and some of the blood coagulates into the vagina. That's why it comes out in the form of clots.
