Why is the labia itchy? It may be because of this

Itchy labia and vulva as well as some white discharge may all be caused by vaginitis. Itchy labia is a symptom caused by bacterial invasion of the genitals. Common causes include Trichomonas infection, fungal infection, and allergies.

(1) Infectious factors: Trichomonas infection or fungal disease is the most common cause of vulvar itching. When suffering from Trichomonas vaginitis or bacterial vaginitis, or cervical erosion, the amount of leucorrhea increases significantly, and the inflammatory secretions irritate the vulvar skin and mucous membranes, causing itching. In addition, pubic lice, pubic scabies and some sexually transmitted diseases can also cause vulvar itching. Pinworm disease is common in young girls, mainly causing itching around the anus, which may spread to the vulva and occur at night.

(2) Local vulvar lesions: Vulvar skin diseases such as vulvar eczema, neurodermatitis, chronic vulvar dystrophy, vulvar tumors, etc. can all be causes of vulvar itching.

(3) Bad hygiene habits: Not paying attention to cleaning the vulva, causing vaginal secretions or menstrual blood to accumulate in the vulva, causing itching. On the contrary, washing the vulva several times a day, or frequently using strong alkaline soaps, or washing the vulva with potassium permanganate water will make the vulva skin too dry and cause itching.

(4) Inappropriate clothing: Wearing synthetic underwear or using menstrual belts made of rubber or plastic will cause poor ventilation of the vulva skin, causing it to be soaked with sweat and itchy.

(5) Allergy: Allergy to systemic or local medications in the vulva causes vulvar itching.

(6) Systemic diseases: Vulvar itching caused by vitamin A and B deficiency, jaundice, anemia, leukemia and other diseases is part of systemic itching. The diabetes in diabetic patients irritates the vulva and is also a common factor causing itching. In addition, obese patients may experience vulvar itching due to excessive secretion of sebaceous glands and sweat glands, which stimulate the vulva.

(7) Irritation from feces and urine: In a very small number of patients, due to urethrovaginal fistula, urinary incontinence, or anal fistula, feces and urine may irritate the vulva for a long time, causing itching.

(8) Psychological factors: Some patients are unable to identify the cause of vulvar itching, which may be due to excessive mental stress.

(9) A small number of patients experience itching due to vulvar congestion before menstruation or during pregnancy, but no abnormalities are found during clinical examination.
