Patient's question:
Is it normal for menstruation to be dark red?Doctor's answer:
Hello, dark-colored menstrual blood may be related to inflammation. It is mostly due to intrauterine inflammation, cervical inflammation, vaginal inflammation, etc. This is because menstrual blood mixes with fragments of shed endometrium, cervical mucus, and vaginal epithelial cells, so it appears darker and is not as bright red as blood from skin damage. Additionally, some small thin fragments are mixed in the menstrual blood. Especially for some people with relatively light menstrual flow, if the blood stays in the uterus or vagina for a longer time, the color becomes even darker.
