Vaginitis is a common gynecological disease, including trichomoniasis, vulvovaginal pseudomonal yeast disease, and bacterial vaginosis, etc. If women have poor immunity and vaginal microecological imbalance themselves, it is easy to have recurrent attacks. Therefore, when vaginitis occurs, in addition to standardized treatment, it is important to practice good personal hygiene, strengthen physical exercise, and use probiotics to improve the vaginal microecology if necessary. Since the perineum is moist and adjacent to the urethra and anus, and the vagina is thick and short and connected to the external environment, bacteria can easily breed and multiply in large numbers and re-infection if care is not taken to clean it. Therefore, women should wash their vulva with fresh water daily and choose loose and breathable cotton underwear to prevent bacterial growth and infection. It is recommended to diversify the diet and consume more fresh fruits and vegetables, such as oranges and kiwis, to replenish the body with the necessary nutrients.
