What are the causes of mild vaginitis?

Vaginitis is an inflammation that occurs in the vagina. There are many types of diseases, which are divided according to the type of infected bacteria. There are not many symptoms when the disease is first infected. Some patients cannot even find abnormalities until vaginal discomfort symptoms appear. They will find that they may be infected with vaginitis. Patients need to know the cause of the disease to accurately prevent the occurrence of the disease. So what is the cause of mild vaginitis?

1. Bacterial vaginosis

In a normal vagina, lactobacilli that produce hydrogen peroxide are dominant. Bacterial vaginosis is an endogenous mixed infection caused by a decrease in Lactobacillus and an increase in Gardnerella and anaerobic bacteria in the vagina.

2. Candidal vaginitis

(1) 80% to 90% of pathogens are Candida albicans, which grow easily in an acidic environment and are diphasic (yeast phase and hyphae phase).

(2) The patient's vaginal pH is between 4.0 and 4.7, usually <4.5.

(3) Conditionally pathogenic bacteria (yeast phase → mycelium phase).

(4) Common causes: pregnancy, diabetes, and large-scale use of immunosuppressants and broad-spectrum antibiotics.

(5) Other contributing factors: gastrointestinal Candida, wearing tight synthetic underwear, and obesity.

3. Trichomonas vaginitis

(1) Trichomonas vaginalis grows best in a humid environment with a temperature of 25℃ to 40℃ and a pH of 5.2 to 6.6.

(2) The vaginal pH changes before and after menstruation, becoming close to neutral after menstruation, making it easier for Trichomonas to reproduce.

(3) The vaginal pH of patients is generally between 5.0 and 6.5, and most are >6.0.

(4) Parasitic on the vagina, urethra or paraurethral glands, bladder, renal pelvis, male foreskin folds, urethra, and prostate.

(5) Often coexists with other vaginitis.

4. Senile vaginitis

Postmenopausal women have declining ovarian function, lower estrogen levels, vaginal wall atrophy, thinning mucosa, increased vaginal pH, reduced local resistance, and other pathogenic bacteria may over-multiply or easily invade and cause inflammation, mainly aerobic bacteria.

5. Vaginitis in young girls

It is caused by poor development of the vulva, low estrogen levels and foreign objects in the vagina of infants and young children, which trigger infection. Common pathogens include Escherichia coli, Staphylococcus aureus, Streptococcus aureus, etc.

This is the end of the explanation of the causes of mild vaginitis. After knowing the factors that cause the disease, you can take targeted prevention measures and stay away from the occurrence of vaginitis. The main symptoms of the disease are vaginal itching, and abnormal leucorrhea may be observed. After the patient finds this abnormality, a leucorrhea examination can be done in the hospital to confirm the diagnosis, and the disease can be diagnosed and treated.
