What is the reason for blood streaks in vaginal discharge?

A common problem among girls is that there are some minor problems with their leucorrhea. However, some girls think that abnormal leucorrhea is nothing and it will get better on its own. In fact, this is a very scary idea, because you must pay attention to your body. Even a small problem is worth your attention. So let's talk about why there is blood in the leucorrhea after wearing an IUD.

Western medicine believes that the vaginal environment is often unstable due to the host's metabolic products, the bacteria's own products and exogenous factors (sexual intercourse, douching and other interference). The vaginal flora is very complex. In addition to protozoa and fungi, it also includes many aerobic and anaerobic bacteria. These microorganisms can be divided into commensal and pathological ones. They all grow in a common environment and there may be antagonism between the microorganisms.

Another factor that affects its growth is the hydrogen ion concentration. At pH 3.8~4.2, it is conducive to the reproduction of commensal bacteria, especially Lactobacillus, which is the main species in a healthy vagina. The density in vaginal fluid can reach 105~108ml. When the vagina is infected by microorganisms, if Lactobacillus is dominant and can still maintain pH 3.8~4.2, it will not cause disease. Moreover, Lactobacillus can also produce H202, which is toxic to other microorganisms and inhibits their reproduction. Others such as Streptococcus lactis, Enterobacter, Proteus, Gavagelococcus, and Veillonella are common in the lower end of the vagina and usually do not cause symptoms. The vaginal flora restrain each other, preventing pathological bacteria from having any effect. If this balance is disrupted, the mutual restraint disappears, so the hydrogen ion concentration decreases, lactobacilli lose their advantage, and pathological bacteria are able to multiply, resulting in symptoms. Bacterial vaginosis is a mixed infection caused by a decrease in lactobacilli in the vagina and a massive proliferation of other bacteria, mainly Gardnerella, various anaerobic bacteria and mycoplasma.

So bacteria are really very scary things. They will always affect our physical health. If you bleed again next time, you should know the approximate cause and go to the hospital for treatment immediately. I believe that after a period of rest and adjustment, this situation will basically not happen again.
