A woman’s sudden onset of vaginitis may be caused by bacterial infection, fungal infection, parasitic infection, and decreased estrogen levels.
1. Bacterial infection: under normal circumstances, the vaginal flora is dominated by lactobacilli, when the pH value of the vagina rises, the vaginal micro-environment is out of balance, other microorganisms will reproduce in large quantities, thus triggering bacterial vaginitis, in addition, sexual disorganization, frequent sexual intercourse, bad habits, vaginal douching and so on can increase the risk of developing this disease.
2. Fungal infection: Pseudomonas aeruginosa mostly resides in the vagina. When the immune function of the whole body or the local vagina decreases, Pseudomonas aeruginosa will invade the tissues around the vagina, thus triggering vulvovaginal pseudomonas aeruginosa, which may be related to the long-term application of broad-spectrum antibiotics, diabetes mellitus, and accepting a large amount of estrogen treatment.
3. Parasitic infection: mainly caused by Trichomonas vaginalis infection, which is mainly transmitted directly through sexual behavior. In addition, not paying attention to personal hygiene, such as using public baths and sitting, etc., can also trigger the disease.
4. Decrease in estrogen level: postmenopausal women can be due to the decline or absence of ovarian function, resulting in a decrease in the level of estrogen, decreased resistance, decreased ability to kill pathogens, resulting in infection with pathogenic bacteria, which can lead to vaginitis.
In addition, there are other reasons that can cause a woman to suddenly get vaginitis, it is recommended to go to the hospital in time to identify the cause of the disease, and then receive treatment as soon as possible.
