Often, blood clots are caused by a hormonal imbalance. Sometimes, however, it can also be caused by conditions such fibroids, cysts and even endometriosis.

According to the Colombian Obstetrics and Gynecology Federation (FECOLSOG, Spanish acronym), this complication affects a large percentage of women of childbearing age and generally occurs with other types of conditions.

Causes: A hormonal imbalance

Specialists from this federation also explain that people often attribute this condition to a blood clotting problem, when in reality, this is rarely the case. Menstrual blood clots are more commonly due to a temporary or occasional hormonal imbalance.

A hormonal imbalance refers to an imbalance in the production of sex hormones (normally there is more progesterone than estrogen), causing the endometrium to develop incorrectly.

Fibroids or polyps?

While both conditions can cause menstrual clots, fibroids are the more common cause. (Related article: Polycystic ovary syndrome).

Fibroids: These are benign tumors that must be checked up on regularly. Since these start in the uterus, they can easily affect the endometrial lining or endometrial mucosa, leading to menstrual blood clots.

Endometrial polyps: These appear when the endometrium grows in an excessive and irregular nature, causing polyps to form. Generally, these make for periods that tend to be irregular and are also what form blood clots, although not to the same degree as with fibroids. If they are small, they go away on their own. They can also be removed by outpatient surgery.

Keep in mind that with women who want to become pregnant, if a woman has already been fertilized, a very heavy period may actually mean she had a miscarriage.
