Why does a nine-year-old girl have discharge?

Generally speaking, both boys and girls enter puberty at least when they are twelve or thirteen years old, of course there are definitely some exceptions. For example, some parents often feed their children foreign fast food, which results in their children's precocious puberty. Secondary sexual characteristics do not appear during puberty, but appear earlier. In real life, some girls even have discharge at the age of nine. Why is that?

A nine-year-old girl has vaginal discharge, which may be related to normal leucorrhea or vaginitis. If there is no change in sexual characteristics such as breast development, and only leucorrhea appears, it is a normal phenomenon. If it is accompanied by breast lumps, it may be related to precocious puberty. In addition, vaginitis causes increased secretions, which will have a distinct odor, accompanied by vaginal itching and pain.

Vaginitis, or inflammation of the vagina, is a group of conditions that cause vulvovaginal symptoms such as itching, burning, irritation, and abnormal discharge. The vagina of a normal healthy woman has a natural defense function against the invasion of pathogens due to the characteristics of its anatomical tissue. For example, the closure of the vaginal opening, the close contact of the anterior and posterior walls of the vagina, the proliferation of vaginal epithelial cells and the keratinization of surface cells under the influence of estrogen, and the balance of vaginal acidity and alkalinity inhibit the reproduction of alkaline-adapted pathogens. The cervical mucus is alkaline. When the natural defense function of the vagina is destroyed, pathogens can easily invade and cause vaginal inflammation.

Under normal circumstances, aerobic bacteria and anaerobic bacteria live in the vagina, forming normal vaginal flora. If the ecological balance between the vagina and the bacterial flora is disrupted for any reason, conditional pathogens may also form. Common clinical diseases include: bacterial vaginosis (accounting for 22% to 50% of symptomatic women), candidal vaginitis (17% to 39%), Trichomonas vaginitis (4% to 35%), senile vaginitis, and vaginitis in young women.
