The color of menstrual blood during menstruation in women should be dark red or deep red. If the discharged menstrual blood has obvious black hair and purple color, it is considered abnormal menstrual blood color. This situation should be taken seriously and the cause should be investigated. So, what is the reason why female menstrual blood is purple black?
1. If the color of menstrual blood turns black during the early stages of menstruation or near the end of menstruation, this is a normal situation. Mainly due to the low menstrual blood volume during this stage, it stays in the uterine cavity or vagina for a longer time, which can cause iron in the blood to be oxidized and form iron oxide, resulting in a darker color of menstrual blood and a darker appearance.
2. If the menstrual blood during the entire menstrual cycle is purple black, it is considered an abnormal situation, mainly due to the presence of uterine coldness or symptoms such as qi deficiency, blood stasis, liver qi stagnation, and damp heat. These reasons can lead to poor menstrual blood discharge and reduced menstrual blood volume in women, as well as changes in the normal color of menstrual blood.
3. If women suffer from gynecological inflammatory problems, such as cervical inflammation leading to cervical adhesions, or endometritis leading to endometrial adhesions, it can also cause menstrual bleeding to stay in the uterine cavity for too long, resulting in darker colors. So we also need to consider whether there are such reasons causing abnormal color of menstrual blood. If women experience long-term blackening of menstrual blood color, it is recommended to seek medical attention and examination at the gynecology department of the hospital in a timely manner.
