Regarding vaginitis, you need to be clear about these 5 points

In 2020, the China Disease Control and Prevention Center’s survey on women’s reproductive health shows that in the past year, 53.86%of adult women have suffered from vaginitis, of which 9.48%have repeatedly developed 4 times.So, what exactly is vaginitis?Why does vaginitis occur …

This article summarizes 5 important contents related to vaginitis or can provide reference.

1. What is vaginitis?

Vaginitis (vaginal inflammation) is a gynecological disease often encountered in the clinic.Diagnosis is usually based on abnormal discharge and/or vulva discomfort.Cervicitis can also cause abnormal discharge, and sometimes it is accompanied by vaginitis.

Liquid flows out of the vagina every day to maintain the normal healthy environment of women.Normal discharge is usually transparent or milky white without bad odor.If the number, color, or odor of vaginal discharge changes, or patients with stimulation, itching, or burning pain may be due to the imbalance of healthy bacteria in the vagina, which leads to vaginitis.

Among the symptoms of female patients, the most common diseases in vaginitis are due to bacterial vaginal disease (40%-45%), vaginal cataches (20%-25%), and trichomonas infections (15%-20%);However, 7%-72%of vaginitis women are still not diagnosed.

2. What is the pathological mechanism of vaginitis?

Complex microorganisms can maintain normal vaginal flora.Important microorganisms in the vagina include lactobacillus, Bacterium and yeast.Oxygen and anaerobic bacteria can be cultivated in the early period, adolescence and adult women’s vagina.

The following factors can change the composition of vaginal flora:


• Sexual behavior (or sex abuse);

• Hormone status;

•Hygiene Situation;

• Immune state;

• Basic skin disease.

Under normal circumstances, the pH value of menstruation and menopause is 3.8-4.2.Under the pH value, the growth of pathogenic microorganisms is usually suppressed.In a healthy vagina, the disorders of the pH value will change the vaginal flora and lead to excessive growth of the original microorganisms.The following factors may affect the vaginal environment:

• Women’s sanitary products;

• contraceptives;

• Vaginal medication;


• Sexual Communication Disease (STD);

•sexual intercourse;


Excessive growth of normal bacteria, infectious bacteria or viruses can cause vaginitis symptoms.In addition, chemical stimulation is also an important factor.Atrophic vaginitis is related to the low level of estrogen, and its symptoms include difficulty in sexual intercourse, dryness, itching and abnormal bleeding.A decrease in estrogen levels may cause changes in risk of infection.

Kenyon and Colebunders analyzed data from 11 countries/regions, showing that when women’s male partners have multiple other sexual partners at the same time, the risk of bacterial vaginitis in the woman has increased.

Age can affect the anatomy and physiological conditions of the vagina.Compared with adolescence and adolescence, the vaginal pH value of women before adolescence is higher.The vaginal mucosa is a scale -like epithelium, without vaginal mucus glands, and the vaginal flora is similar to that after menopause women (for example, the Gram -positive bacteria and anaerobic Gram -negative bacteria are more common). The labia are thin and the hymen is thin.

The female vaginal pH value of women in adolescence and adolescence is lower (more obvious in acidic environment), vaginal mucosa is a compound layer -like epithelium, the vagina has mucus glands, the normal flora is mainly lactobacillus, thicker labia, hymen and vaginal wall hypertrophyEssenceAmong these female patients, the reduction of vaginal lactobacterium seems to be the main factor that causes bacterial vaginitis.The recurrence of vaginitis is associated with a healthy vaginal flora environment that failed to establish lactobacillus.

3. What is the cause of vaginitis?

About 90%of vaginitis is caused by three causes of bacterial vaginal disease, vaginal adopycosis (or vulvar vulva, vulva, and vulva, and vaginal tricia.

Bacterial vaginal disease is the most common cause of vaginitis, accounting for about 50%of vaginitis.It is mainly due to the excessive growth of microorganisms such as Gardnenerlla Vaginalis, Mobiluncuspecies, Humancopo and Peptostocococus Species.The risk factors of bacterial vaginitis include the use of and cleaning the internal in -the -palace.

Candida is a fungus, mainly including Candida, Tropical Candida, and CGLABRATA, and naturally lived in 50%of female patients.Candida disease is the second most common cause of vaginitis.Among them, 85%-90%are caused by Candida, and 5%-10%are Grabler’s Candida Candida and Candida Candida (C. PSEUDOTROPICALIS).Dangerous factors include pregnancy, oral contraceptives, the use of internal adusters, the age of first sexual intercourse, frequent sexual intercourse, oral sex, diabetes, AIDS/other low immune function, and long -term use of antibiotics.

Trichomonas infection is the third most common cause of vaginitis.Trichomonas is a very tiny bioplasm of the whip hair. It is mainly infected with vaginal epithelium and can also be infected with endometrium and urethra, but it is not common.Trichomonas infection is mostly sexually transmitted, and can be detected in male partners (80%) of most female patients.Its risk factors include smoking, no protective sexual intercourse with multiple personalized partners, and the use of in -palace.

Non -infectious vaginitis is usually caused by allergies or stimulation.In addition, estrogen deficiency can cause atrophic vaginitis.

In order to prevent bacterial and Candida vaginitis, it is recommended that female friends do not wear humid and tight clothes, nor do they recommend using fragrance, soap, and female spray.In addition, maintain good hygiene habits.

Women of all ages will be affected by vaginitis, and vaginitis is more common among active female patients.In adult women, vaginitis is more common and is rare in women before adolescence.Under normal circumstances, bacterial vaginitis can account for 40%-50%of vaginitis cases, 20%-25%-25%of rosary vaginitis, and trichomonas vaginitis accounted for 15%-20%.

In the United States, bacterial vaginitis is the most common vaginitis.It is estimated that there are 7.4 million new bacterial vaginitis each year, with a national prevalence of 29%.85%of bacterial vaginitis asymptomatic.The cost of self -treatment and medical treatment is more than 1 billion yuan each year.

In addition, 3 million titured vaginitis can occur in the United States each year.The number of cases of trichomoniasis vaginitis is about 174 million.

In general, patients with vaginitis are better, and most infected people can cure it.However, repeated vaginal infections can lead to chronic stimulation, epidermal shedding and scar formation.Conversely, these can also cause sexual dysfunction, and may have psychological or emotional pressure.

Although no literature has proven to treat bacterial vaginitis to prevent AIDS, bacterial vaginitis and sexually transmitted diseases, including trichomoniasis, are considered risk of HIV.

Chronic vaginal infections can promote the spread of various sexually transmitted diseases, including AIDS.The complications of bacterial vaginitis include endometritis and pelvic inflammatory disease.Unprocessed bacterial vaginitis may also cause complications after gynecological surgery, such as vaginal wound infection.

In addition, among women during pregnancy, trichomonas infection and bacterial vaginal disease are related to increased risk of adverse pregnancy ending, including premature birth, premature fetal membrane, low weight, and endocardial endometritis.
