Vulvar itching is a common symptom that can be caused by various factors. Common causes include fungal or bacterial infections, such as yeast infections, which result from an imbalance in the microbial environment of the vagina. In addition, itching can also be caused by trichomoniasis infection, bacterial vaginosis, and other conditions. Bacterial vaginosis may also present with symptoms such as vaginal odor and increased vaginal discharge, in addition to itching.

In addition to infections, skin diseases can also lead to vulvar itching. Over-cleansing, using irritating sanitary products, and friction from tight clothing are also common triggers. Systemic conditions such as endocrine disorders, diabetes, and immune system diseases can sometimes manifest as vulvar itching. Other contributing factors may include prolonged failure to change underwear, poor hygiene of the genital area, and decreased physical resistance.

If vulvar itching occurs, it is recommended to seek timely medical examination to determine the specific cause and receive appropriate treatment. At the same time, maintaining good lifestyle and hygiene habits can also help prevent and treat vulvar itching.
