What causes inflammation in girls?

Vaginitis is a very common gynecological inflammation. Women suffering from vaginitis will have abnormal leucorrhea and vulvar itching, which seriously affect women's daily life and work. There are many types of vaginitis, and different vaginitis symptoms are also different. The treatment methods and causes are also different. During the treatment of vaginitis, you must not have sexual intercourse and you must pay attention to local hygiene at ordinary times.

1. Causes of disease

There are many causes of vaginitis, the most common ones are as follows:

① Abuse of broad-spectrum antibiotics

Long-term use of broad-spectrum antibiotics can inhibit the growth of Lactobacillus, break the occupier protection of Lactobacillus, and give other microorganisms the opportunity to multiply.

② Frequent sexual intercourse

After sexual intercourse, the vaginal pH value can rise to 7.2 and maintain 6-8. Frequent sexual intercourse can keep the vaginal pH in a neutral or alkaline environment, which is conducive to the growth of pathogenic microorganisms. Moreover, frequent sexual intercourse also increases the chance of infection by external pathogenic microorganisms.

③ Vaginal douching

Vaginal douching can also increase the pH value of the vagina, which is not conducive to the growth of lactobacillus.

④ Decrease in estrogen

After menopause, the estrogen level in women decreases, the vaginal epithelium becomes thinner, and the pH rises, which can also cause other pathogens to become dominant and cause inflammation.

For example, Candida not only parasitizes in the vagina, but also exists in the human mouth and intestines. These three parts can be transmitted to each other and can cause infection once the conditions are right.

⑥Exogenous infection

Some vaginitis can be transmitted indirectly through sexual intercourse, public baths, bathtubs, toilets, clothing, etc. For example, Trichomonas vaginitis.

⑦ Decreased body resistance

The destruction of the body's own defense function also gives pathogenic microorganisms an opportunity to take advantage.

More than 20 kinds of microorganisms can be isolated from the vagina of normal women, among which bacteria are the main ones. Common bacteria include: Lactobacillus, Corynebacterium, non-hemolytic Streptococcus, Enterococcus and Staphylococcus epidermidis, Gardnerella, Escherichia coli, Peptococcus, Mycoplasma and Candida, etc. Although there are many microorganisms in the normal vagina, there is an ecological balance among these microorganisms and they will not cause vaginal inflammation.

The so-called balance means that Lactobacillus is dominant among many microorganisms. It can produce hydrogen peroxide and other antimicrobial factors to inhibit or kill other bacteria. This occupier protection of Lactobacillus can form an acidic vaginal environment and produce nutritional competition, which is not conducive to the growth of other microorganisms. However, when the human body's immunity is low, endocrine hormones change, or external factors such as tissue damage and sexual intercourse disrupt the ecological balance of the vagina, these resident bacteria will become pathogenic bacteria, break through the vaginal barrier and cause infection.
