Why do girls feel hot down there?

If girls often feel hot down there, it may be due to some gynecological diseases. Especially for female friends who do not pay attention to personal hygiene, the probability of this happening will be greater. The most common gynecological disease is bacterial vaginosis. During the attack, patients will often feel symptoms of vaginal itching and fever, as well as vaginal stinging. Therefore, do not have sex during this period.

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 4.0-4.7, 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 of them 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.

10% to 40% of patients have no clinical symptoms. Those with symptoms mainly present with increased vaginal discharge with a fishy odor, which is especially aggravated after sexual intercourse and may be accompanied by mild vulvar itching or burning sensation. Examination showed no signs of congestion or inflammation in the vaginal mucosa. The secretions were grayish white, uniform, thin, and often adhered to the vaginal wall, which could be easily wiped off.
