Vulvar itching can be caused by these reasons

Vulvar itching is a symptom caused by different lesions, female vulvar pruritus is mainly in the labia majora and labia minora, partially involving the anus, due to continuous scratching, often accompanied by skin hypertrophy and maceration, clitoris and vaginal mucosa prone to redness and erosion.

Symptoms of itching in women are caused by a variety of reasons, the common ones are as follows:

● Local stimulation of the vulva

Vaginitis causes irritating vaginal discharge:

The most common are

Vulvovaginal candidiasis

(Also known as mycovaginitis, vulvovaginal candidiasis)

, 75% of women will have it at least once in their lifetime. Secondly

Trichomonas vaginitis, bacterial vaginitis


Urine or fecal irritation:

Impersonation of urine or fecal fluid in patients with genital tract fistula causes pruritus in the vulva.

Labia majora creases

Accumulation of dirt


(e.g. pinworms, pubic lice)

Chemical products

Chemical fiber or woolen underwear

and so on, can cause itching of the vulva.

● Vulvar localization

Primary disease

It is more common in skin diseases with nonneoplastic lesions within the epithelial epithelium of the vulva

(eg, vulvar eczema, chronic lichen simplex, lichen sclerosus, vulvar squamous epithelial hyperplasia)

, may also be seen in vulvar tumors

(Vulvar epithelioma-like lesions and invasive carcinoma)

● Sedentary bad habits

The shape of the vulva allows warm, moist secretions to maintain long-term contact with the skin, but sitting for a long time can easily lead to dampness and occlusion of the vulva, changes in temperature and humidity, and obstruction of blood circulation.

This causes itching of the vulva, and the long-term hot and humid environment is also a breeding ground for bacteria.

For bacterial vaginosis, sexual activity may be a risk factor for its development, but there is currently insufficient evidence for bacterial vaginosis due to sexual transmission.

No treatment is required for asymptomatic sexual partners.

If vaginitis due to microbial infection
