What is the reason for the black menstrual period?

Menstruation, commonly known as period, is also called menstruation. During menstruation, women will lose a lot of blood. Of course, this is normal. To some extent, it is a detoxification phenomenon that is beneficial to women's bodies. However, only normal menstruation is beneficial to women's health. If the menstruation is black and the amount is small, it is a warning sign that there is something abnormal in the female body. Women have many physical signs to judge whether they are healthy or not, and menstruation is one of them. Under normal circumstances, women's menstruation is regular and quantitative, and the color is bright red. So why is the menstruation black and the amount is small? Let’s quickly learn about it.

Generally speaking, black menstruation is caused by qi stagnation and blood stasis, and menstrual blood has been stagnant in the uterus for a long time. Oligomenorrhea refers to less menstrual volume than normal people during menstruation, which is mostly caused by blood deficiency, qi stagnation, blood stasis, cold stagnation in the blood, phlegm obstruction and other reasons. However, there are also some diseases that can cause irregular menstruation, scant menstruation and dark menstrual color: including local inflammation of the reproductive organs, tumors and developmental abnormalities, malnutrition, intracranial diseases, other endocrine dysfunctions such as thyroid and adrenal cortex dysfunction, diabetes, Sheehan's disease, liver diseases, blood diseases, etc. Menstrual irregularities may occur in women who use psychiatric drugs, endocrine preparations, or intrauterine devices for contraception. Another cause is neuroendocrine dysfunction: mainly the instability or defect of the function of the posterior brain-pituitary-ovarian axis, that is, menstrual disorder.

Of course, one thing female friends should know is that menstruation is affected by many factors. When the menstrual period is black and the amount is small, female friends should not worry blindly. It may be due to the influence of some external factors, not a big problem with their own health, such as acclimatization, etc. However, if external factors are ruled out, everyone should be careful and consult a doctor in time.
