Menstrual blood clots

Typically, women who experience an excessive bleeding during their periods also present menstrual blood clots. This clotting often causes painful cramps when large clots pass through the cervix.

Causes of menstrual blood clots

Menorrhagia

A heavier bleeding than usual during your period may drain your body’s anticoagulant ability, therefore causing larger clots.

Endometriosis and IUD

Endometriosis, or uterine fibroid, may lead to an excessive clotting during the menstrual cycle. Sometimes, women using a IUD (intrauterine device or coil) might experience a heavier bleeding with larger clots. Nevertheless, at times there is no explanation for clotting.

Pelvic floor dysfunction

Fibroids, polyps, Pelvic Inflammatory Disease (or disorder) (PID), an increased thickness of the uterine lining or endometrial cancer may occasionally lead to blood clotting. This is the reason why it is recommended to see a doctor in order to dismiss severe problems.

Hormonal and blood factors

Women with hormonal imbalances may have a higher risk of excessive bleeding, which leads to clotting. Other reasons may be: underactive thyroid gland, possible blood disorders or blood-thinning medications.

Women with hormonal imbalances are more prono to experience heavy periods

Stress

Often ignored, stress is a very common factor leading to excessive bleeding. Sometimes, blood clots during menstruation are just a way in which your body throws away the uterine tissue. Overall, the aim of the menstrual cycle is getting rid of toxins and waste, which are usually expelled as blood clots.
