In our WeChat circle of friends, there is always a group of people who tirelessly make an issue of their great aunt:
What’s great aunt has a small number of blood vessels and poor blood flow, which requires “blood purification”.
What’s great aunt has a large quantity and is not clean because there are too many toxins and “deep detoxification” is needed.
There are also people who send out a menstruation towel with heavy taste stained with dark brown menstrual blood in the circle of friends in the morning, accompanied by:
Menstrual blood is dark in color and has blood clots. It is cold in the uterus, which will lead to gynecological diseases and premature ovarian failure. It is necessary to do uterine warming and ovarian maintenance quickly.
In the end, should the normal big aunt be what color?
Composition of menstrual blood
The source of menstrual blood is the bleeding caused by periodic necrosis and exfoliation of our endometrium every month. However, this blood is not only composed of blood components, but also includes endometrial fragments, mucus secreted by the cervix and exfoliated vaginal epithelial cells.
If at the beginning, the endometrium falls off less and the mixed cervical mucus is more, then the blood color may be lighter, so many women’s menstrual blood color is darker at the beginning of menstruation.
Most of menstrual blood is composed of arterial blood, mixed with a part of venous blood. As we have said, arterial blood has high oxygen content and more bright red color, while venous blood has low oxygen content, so the color is darker.
If the venous blood volume is relatively large in the composition of menstruation, the color will look darker.
Amount of menstruation
We usually call the total amount of bleeding from the beginning to the end of a menstruation the amount of menstruation. The common amount of menstruation for normal women is between 20 and 60 milliliters. More than 80 milliliters we call menorrhagia.
If the amount of menstruation is more, the menstrual blood will quickly flow out of the filled uterine cavity, and the color will look brighter. If the amount of menstruation is less, the time from the uterine cavity to the outflow will be longer, and the color will look darker.
Time
If menstrual blood flow out, you just saw, and immediately replaced the sanitary napkin, then this time, still warm menstrual blood looks bright color. If such as blood flow out, after being absorbed by sanitary napkins, after a period of time to see again, the color will be darker.
During the time stored in the uterine cavity and vagina, the iron element in the blood will slowly oxidize and darken, while the oxygen content of hemoglobin will decrease, so it looks darker.
Sanitary napkin material
If you have changed sanitary napkins made of different materials, you will find that the menstrual blood color on the surface of different sanitary napkins is different. Because of curiosity, I also personally evaluated it and found that it is true.
This may be related to the different surface materials of sanitary napkins. For example, for sanitary napkins with mesh surface, the menstrual blood after absorption looks darker, while the menstrual blood absorbed on soft cotton surface is relatively red.
Blood clot
Why are there blood clots? To tell you the truth: because fibrinolytic enzyme is not enough!
The reason why menstrual blood does not coagulate is that it contains a large amount of fibrinolytic enzyme from the endometrium. If your fibrinolytic enzyme is just enough for your menstrual blood, then there will be no blood clots in your menstrual blood. If your fibrinolytic enzyme is less and the amount of menstrual blood is more, then blood clots will naturally form.
Therefore, don’t immediately report to the hospital as soon as you see blood clots, and even run to make what’s “Warm Palace Nest Package”!
Well, having said that, I want to tell you that the normal answer to the above question is:
These colors can be the colors of normal aunts.
Normal menstruation, we generally think, menstrual cycle in 21 ~ 35 days, averaging 28 days a cycle. The duration of a menstruation, generally in 3 ~ 7 days or so. And a menstrual bleeding volume, generally in 5 ~ 80 milliliters.
However, because of the large individual differences in menstruation, when we look at whether a woman’s great aunt is normal, we should also consider one word, that is stability.
If the originally stable big aunt suddenly has an abnormality, then the safest way for us to find out the reason is to go to a regular hospital instead of running to a circle of friends or buying what menstruation pills with unknown ingredients on the Internet. I’m afraid we have to eat something wrong even if there is nothing wrong with it!
It seems that there are always many routines around us, which will be fooled if we are not careful.
