What are the causes of vulvar itching?

Vulvar pruritus is a common phenomenon in many women. There is a saying that "nine out of ten people suffer from itching", which describes the large number of patients suffering from vulvar pruritus. So what are the causes of vulvar pruritus? The causes of vulvar pruritus can be roughly divided into local and systemic. Let's take a closer look below.

1. Local reasons:

Inflammation: Vaginitis or cervicitis caused by infections such as Trichomonas, fungi, bacteria, chlamydia, mycoplasma, gonorrhea, etc., the large amount of abnormal leucorrhea discharged will irritate the vulva and make it itchy.

Vulvar skin diseases: such as vulvar eczema, neurodermatitis, atrophic lichen sclerosus, vulvar dermatitis, etc. These diseases can not only cause varying degrees of itching, but also the vulvar skin may have varying degrees of whitening, atrophy or thickening changes.

Local irritation:

If the vulva and vagina are flushed with disinfectant, or certain drugs (such as sulfonamides, furacillin, chlorhexidine suppositories, etc.) are placed in the vagina, it may cause vulvar skin allergies or dermatitis.

If you do not pay attention to hygiene during menstruation, or use rubber or plastic menstrual belts, and fail to clean the vulva regularly, menstrual blood or vaginal secretions will accumulate in the vulva for a long time. Or if you usually wear synthetic underwear, the vulva is often in a wet and hot environment, which can often cause vulva itching.

Frequently washing the vulva with highly alkaline soap or hot water will cause the vulva skin to become dry, lack oil and become itchy.

In people with pinworm disease, pinworms often crawl out of the anus and irritate the area around the anus and the vulva, causing itching, especially at night, and even affecting sleep.

2. Certain systemic diseases can also cause vulvar itching:

1. The most common cause is diabetes. Due to the frequent excretion of sugary urine, the vulva will be irritated and it will become itchy. If it is complicated by fungal infection, the itching will be even worse.

2. When suffering from diseases such as jaundice hepatitis, riboflavin deficiency, anemia or chronic hepatitis, the whole body will itch, including the vulva.

3. Excessive fatigue, mental trauma or conditioned reflexes: Sometimes there is no obvious local or systemic cause for vulvar itching, and no changes can be seen in the vulva. This kind of vulvar itching that cannot be found is likely caused by high mental stress, mental trauma or conditioned reflexes.
