Leucorrhea with blood before and after menstruation

There will be leucorrhea before and after menstruation. In addition to ovulation, there will be secretions in the female body. The secretion is leucorrhea. The leucorrhea before and after menstruation is the most obvious. Some people have leucorrhea bleeding. In the case of leucorrhea bleeding, it should be considered physiological, because there is slight uterine bleeding, or normal ovulation period, so there will be this symptom of leucorrhea bleeding.

Causes and treatment

The weakly acidic environment of the vagina can maintain the self-cleaning function of the vagina. Western medicine believes that the environment of the vagina is often unstable due to the host's metabolic products, the products of the bacteria themselves, 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 105-108 ml. 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.

Trichomonas vaginitis is caused by Trichomonas vaginalis and is a sexually transmitted infectious disease. It is transmitted directly (through sexual intercourse, 75% of the semen of the spouse with Trichomonas vaginitis can be found in Trichomonas) and indirectly (through various bathing utensils, swimming pools, public toilets or contaminated clothes and equipment). In the census, the detection rate of Trichomonas was 3.56%, among which some women had no inflammation symptoms and were called carriers.

Candidal vaginitis is mainly caused by Candida albicans. A small amount of these fungi can often parasitize in a normal and healthy vagina, but they generally do not cause disease. When the body's immune function is low or the flora is out of balance, they will multiply and cause disease. Therefore, it is more common in pregnant women, those with diabetes, those using immunosuppressants, and those using antibiotics for a long time. In addition, it is also easy to be infected in a humid and hot environment. According to statistics, about 10% of non-pregnant women and one-third of pregnant women are infected with this disease, but few people seek medical treatment because the symptoms are obvious. As for the incidence of vaginitis caused by non-albicans Candida (such as Torulopsis glabrata), it increased from 9.9% in 1988 to 17.2% in 1995. Women infected with HIV were twice as likely to be infected with non-albicans Candida than those infected with HIV. Women with recurrent candidal vaginitis were 2.47 times more likely to be infected with non-albicans Candida than with albicans.
