I believe everyone must know the importance of the vulva to female friends. We know that if there is a problem with the vulva of female friends, it will not only cause pain to female friends but also threaten their physical health. Therefore, we recommend that female friends must pay great attention to the health of their vulva in daily life. Once there is a problem with the vulva, it should be taken seriously. Below we will introduce the reasons why the vulva is itchy and painful. 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. In the above article, we introduced the importance of the vulva to female friends. We recommend that female friends should protect their vulva in daily life. The above article gives us a detailed introduction to the reasons why the vulva is itchy and painful. I believe everyone has already understood it. |
