Menstrual blood is normally red, but some women may feel scared when they see it turn black, worrying that there may be a problem with the uterus. The situation of black menstrual blood is not uncommon, but it is unknown what causes it and what needs to be paid attention to in order to restore normal menstrual blood. So what causes dark menstrual blood?
Menstrual blood appears black, usually due to a low menstrual flow or poor flow of menstrual blood. Normal menstrual blood should be dark red in color, and due to the presence of fibrinolytic enzymes in menstrual blood, it will not coagulate.
When the amount of bleeding is relatively small or the flow of menstrual blood is not smooth, it causes the menstrual blood to stay in the uterine cavity for a longer time, and when it flows out, it becomes old black brown blood. If this situation occurs, it is necessary to go to the hospital for examination in a timely manner, to check the thickness of the endometrium, the level of sex hormones in the body, and whether the reproductive tract is unobstructed.
If there is a sudden decrease in menstrual flow, it may be due to a recent history of using hemostatic or contraceptive drugs. Generally, it may return to normal after stopping the medication. If it is regular, long-term use of sex hormone drugs is needed to adjust.
During menstruation, it is important to keep warm and avoid catching a cold. Avoid eating raw, cold, or stimulating food, pay attention to local hygiene, rest, and maintain a relaxed mood.
