    Vaginitis may be caused by bacterial infection, fungal infection, parasitic infection, changes in hormone levels, allergic reactions, etc. It can be improved through drug treatment, adjustment of living habits, etc.

    1. Bacterial infection

    Bacterial vaginosis is usually caused by an imbalance of vaginal flora. Common pathogenic bacteria include Gardnerella, anaerobic bacteria, etc. Patients may experience symptoms such as gray-white discharge and fishy odor. Medications such as metronidazole vaginal effervescent tablets, clindamycin phosphate vaginal gel, and tinidazole suppositories can be used as directed by your doctor. You need to avoid excessive vaginal washing on a daily basis and choose breathable cotton underwear.

    2. Fungal infection

    Vulvovaginal candidiasis is mostly caused by the overgrowth of Candida albicans. Common triggers include long-term use of antibiotics and low immunity. Typical symptoms include tofu-like leucorrhea and vulvar itching. Clotrimazole vaginal tablets, miconazole nitrate suppositories, and nystatin vaginal suppositories can be used for treatment. It is recommended to control blood sugar and reduce the intake of high-sugar foods.

    3. Parasitic infection

    Trichomonas vaginitis is caused by the parasite Trichomonas vaginalis and is spread through sexual contact. It is characterized by yellow-green foamy discharge and burning sensation in the vulva. Commonly used drugs include metronidazole tablets, tinidazole tablets, and ornidazole capsules. Sexual intercourse should be avoided during treatment, and partners should be treated simultaneously.

    4. Changes in hormone levels

    Postmenopausal women are prone to atrophic vaginitis due to decreased estrogen levels and thinning of the vaginal mucosa. Symptoms include vaginal dryness and pain during sexual intercourse. Estriol cream can be used topically with a moisturizing lubricant. Appropriately supplement phytoestrogen foods such as soy products.

    5. Allergic reaction

    Contact with chemicals in sanitary napkins, condoms and other items may trigger allergic vaginitis. Symptoms include vulva redness, swelling, and tingling. Allergenic products need to be stopped immediately, and loratadine tablets should be taken orally if necessary. Choose unscented sanitary products and avoid using vaginal douches.

    To prevent vaginitis, you need to keep your perineum clean and dry, change your underwear every day and wash it with hot water. Avoid wearing tight-fitting synthetic underwear and reduce the use of panty liners during non-menstrual periods. Clean before and after sex and do not abuse antibiotics. Seek medical attention promptly when abnormal discharge or itching occurs, and do not self-medicate. The diet should be light, and an appropriate amount of yogurt containing lactic acid bacteria should be supplemented to maintain the balance of vaginal microecology.
