What causes vaginal redness, swelling and itching? Vaginal redness, swelling and itching are usually caused by vaginitis. There are mainly the following types of 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 bacteria (yeast phase and hyphae phase).

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

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

4. Common causes: pregnancy, diabetes, and extensive use of immunosuppressants and broad-spectrum antibiotics.

5. Other causes: 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℃~40℃ and a pH of 5.2~6.6.

2. The vaginal pH changes before and after menstruation, and becomes close to neutral after menstruation, making it easy for Trichomonas to reproduce.

3. The patient's vaginal pH is generally between 5.0 and 6.5, and most are >6.0.

4. Parasitizes in the vagina, urethra or paraurethral glands, bladder, renal pelvis, male foreskin folds, urethra, and prostate.

5. It 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.

The above is an introduction to what causes vaginal redness, swelling and itching. From the above introduction, we can know that vaginitis is the main cause of vaginal redness, swelling and itching. Therefore, friends who have symptoms such as vaginal redness, swelling and itching must go to the hospital for examination in time!
