To know how a woman's physical condition is, just look at the color of her menstrual cycle. The normal menstrual color is dark red. If the color turns black, it is mostly due to coldness in the body, or it may be caused by endocrine disorders. Next, let's take a look at what causes the color to turn black in the last few days of menstruation?
1. Low menstrual blood volume is often caused by low estrogen levels and hormonal imbalances. There are many reasons that can lead to decreased menstrual flow and blackening. In addition to luteal insufficiency, abnormal thyroid and prolactin function, as well as postoperative induced abortion or endometrial adhesions, are also among the reasons. In addition, it also includes long-term malnutrition, environmental changes, high mental stress, improper menstrual care, and catching a cold in the body.
2. Menstruation is infrequent and dark, which is believed by traditional Chinese medicine to be caused by qi stagnation, blood stasis, blockage of the cell veins, and poor blood flow. Therefore, on the first and last days of menstruation, when the blood volume is low, the color of the blood is black brown, which may be caused by the prolonged retention of menstrual blood in the uterus, and often accompanied by dysmenorrhea. If there are occasional episodes of infrequent and dark menstruation, it can be restored to normal by adjusting daily routines. If there are frequent and dark periods, it is necessary to go to the hospital for examination and targeted treatment.
3. During menstruation, catching a cold can lead to blood clots, and prolonged blood clots may increase the risk of uterine fibroids. Blood clots during menstruation are generally rare in young people. If there are blood clots during menstruation, you can go to the hospital for examination to see what the cause is. Under normal circumstances, menstruation is bright red without dark purple blood clots. Once menstruation with dark blood clots occurs, it is often accompanied by dysmenorrhea. Dysmenorrhea often leads to mental tension and emotional instability in patients.
The above is the encyclopedia introduction about what causes the last few days of menstruation to turn black in color. In short, normal menstruation can be restored through traditional Chinese medicine regulation. If the above adjustments have no effect, it is recommended that women with symptoms of infrequent menstruation and prolonged black time go to the hospital to have their hormone levels checked and undergo B-ultrasound examination to see if it is caused by a disease.
