What is the cause of black blood clots during menstruation

Menstruation is a relatively normal physiological phenomenon for women. Normal menstruation is usually bright red and lasts for about 3-7 days. However, if women have black blood clots during their menstrual period, it is very abnormal and long-term existence will cause harm to women's bodies. So what is the cause of black blood clots during menstruation? Let's learn more about it below.

Cause 1: Gynecological inflammation

Black blood clots during menstruation may also be caused by bloody leucorrhea. Leucorrhea with blood in it is a symptom of gynecological inflammation. Bloody leucorrhea is common in gynecological inflammations such as severe cervical erosion, cervical polyps, endometrial cancer, and submucous uterine fibroids. If the disease persists for a long time and is not treated in time, it may lead to ectopic pregnancy in women.

Reason 2: Irregular menstruation

Black blood clots during menstruation is one of the symptoms of irregular menstruation. Some women suffer from endocrine disorders due to excessive fatigue, mental depression, eating disorders and excessive anger. If endocrine disorders are not treated in time, they will cause irregular menstruation. Experts point out that long-term irregular menstruation without regulation will lead to premature menopause, which is a sign of female infertility.

Cause 3: Endometriosis or inflammation of the endometrium

When the menstrual blood is dark in color and accompanied by symptoms such as menstrual blood clots and dysmenorrhea, further examination is needed to determine whether there is a possibility of endometriosis or endometrial inflammation. The treatment methods are different for different situations.

Reason 4: Caused by organic disease or drugs

Including local inflammation, tumors and developmental abnormalities, malnutrition of the reproductive organs; intracranial diseases; other endocrine dysfunctions, such as abnormal thyroid and adrenal cortex function, diabetes, Sheehan's disease, etc.; liver diseases; blood diseases, etc.

Reason 5: Neuroendocrine dysfunction or ovarian problems

The main reason is that the function of the hypothalamus-pituitary-ovarian axis is unstable or defective, which can easily cause the menstrual color to be dark or brown. Menstrual irregularities in women of childbearing age are generally due to poor ovarian corpus luteum function, which is often manifested as a cycle, but the cycle is shortened or prolonged, or the menstrual color is dark and the blood volume increases.

What is the reason for black blood during menstruation? First of all, there are many reasons, such as endometrial inflammation caused by endometriosis and neuroendocrine dysfunction, which can also cause black blood clots after menstruation. So if you want to fully understand the reasons, it is best to go to the hospital for a comprehensive examination and then receive treatment.
