What causes vaginal itching?

Vaginal itching is a relatively common symptom, and there are many causes. It is related to some gynecological diseases, drug allergies, and lack of attention to hygiene. For example, fungal vaginitis can easily lead to symptoms of vaginal itching. In addition, if sexual life is too frequent, it can easily lead to allergies. Some women are allergic to semen or condoms, which can easily lead to vaginal itching.

1. Fungal vaginitis and vaginal trichomoniasis: itching of the vulva and vagina, flushing of the vulva, dregs-like leucorrhea with odor, and scratching may cause eczematous changes of the vulvar dermatitis. A vaginal smear test can be used to distinguish it from the above conditions.

2. Local skin uncleanness: Some women use toilet paper improperly, and the skin of the vulva is soaked by menstrual blood, vaginal secretions, and even urine, feces and sweat, which causes chronic inflammation of the local skin and causes vulva itching.

3. Drug allergy: Fixed drug rash caused by sulfonamides or other drugs used by women with allergic constitution often occurs at the junction of the skin and mucous membrane of the vulva. In addition to local itching, it may be complicated by erosion and exudation. Vulvar itching may also occur if allergic reactions and contact dermatitis occur when using drugs for vaginal washing or vaginal insertion.

4. Pubic lice: Pubic lice often stick to the skin surface or attach to the roots of pubic hair. Pubic lice eggs are grayish white and the size of a needle. The bites of pubic lice and their venom and excrement can cause itching and desquamation of the skin, and may lead to eczematous changes and folliculitis.

5. Sexual allergy: It is an allergic reaction that occurs during sexual intercourse. There are people who are allergic to semen, condoms, and friction.

5. Pinworm infection: It mainly affects young girls, but adult women can also be infected. When the anus relaxes at night, the pinworms crawl out of the rectum and swim to the vulva to mate and lay eggs, and stimulate the skin and mucous membranes of the vulva, causing local itching.

6. Scabies infection: When scabies occurs, the external skin lesions are the most serious, so local itching is also the most obvious.
