Why is the blood black?

All women have experienced menstruation. There are a few days every month when we will find that the blood is bright red when it first comes out, but after a long time it will oxidize and turn black. This is a process that requires evolution, but in the human body it is bright red. However, for some individual physical conditions, the patient's blood secreted is black. In this case, the patient must consider making these judgments.

Darker menstrual blood may be related to inflammation. In fact, the menstrual blood that comes every month is the blood flowing in the blood vessels in the body, and it should be bright red. However, because menstrual blood is mixed with sloughed endometrial fragments, cervical mucus and vaginal epithelial cells, it looks dark in color and is not as bright red as the blood flowing out of broken skin. There are also some small thin fragments mixed in the menstrual blood.

In particular, some people have less menstrual blood, and the color becomes darker as the blood stays in the uterus and vagina for a longer time. Therefore, while paying attention to the color of menstrual blood, you should also pay attention to the menstrual cycle, duration of menstruation, amount of menstruation, and whether you have any discomfort. Suggestions: It is recommended to go to the hospital for a simple gynecological B-ultrasound examination. Do not blindly take medicine.

Menstrual blood color

Normal blood is dark red and is mixed with small fragments of shed endometrium, cervical mucus, and vaginal epithelial cells, but without blood clots. If the menstrual blood is as thin as water, only slightly pink, or black or purple, it is abnormal. If the menstrual blood is completely blood clots, it is also abnormal and there may be other bleeding sites. You should seek medical attention as soon as possible to ensure your health.

In healthy women of childbearing age, the ovaries undergo cyclical changes, with follicles constantly developing, maturing, and being released, accompanied by changes in the secretion of sex hormones. The endometrium, regulated by sex hormones, also undergoes cyclical changes of proliferation, shedding and repair. When the endometrium sheds and bleeds out of the vagina, it is called menstruation. Menstruation usually occurs every 28-30 days, with blood loss of about 50 ml, and lasts for 3-7 days. Regular menstruation is a necessary condition for fertility, indicating that the reproductive system is functioning normally and is an important indicator of female health.

In addition to normal menstruation, there are some special menstruation:

menarche

The human reproductive system remains in a "dormant" state for a long time after birth. As girls grow and develop, they begin to menstruate around the age of thirteen or fourteen. The first menstruation is medically called "menarche". "Menarche" is an important sign of the arrival of female puberty. For some girls, their menstrual cycles may become irregular for some time after their menarche. The main reason is that the menstrual cycle regulation function is not stable enough and is easily affected by internal and external factors, such as physical condition, mood and environmental changes. Attention should be paid to psychological counseling and health care.
