Puritus vulvae is the medical term which means itchy vulva. The vulva is the area of skin just outside the vagina. Most women have a slight vulval itch from time to time. However, pruritus vulvae means the itch is persistent, and causes distress. The itch may be particularly bad at night and may disturb your sleep. About 1 in 10 women sees a doctor about persistent vulval itch at some stage in her life. It can affect any woman, at any age.
Pruritus vulvae is a symptom, not a condition in itself. Pruritus vulvae can be caused by many different conditions. Therefore, if you have a persistent vulval itch, you should see your doctor to find out the cause.
Causes of pruritus vulvae can include the following.
- Infections. For example: thrush, threadworms, scabies, and some sexually transmitted infections.
- Skin conditions may affect vulval skin. For example: eczema, psoriasis, lichen simplex, lichen planus and lichen sclerosus.
- Allergic reaction to soaps, perfumes, deodorants, excessive sweat, condoms, wet wipes, textile dyes, detergents, fabric conditioners, sanitary wear, etc.
- Urinary or faecal incontinence. This can make the skin of the vulva moist and irritated.
- Menopause. Because of lower oestrogen levels, the vulval skin tends to become thinner and drier after the menopause, which can make it prone to itch.
- Pregnancy can cause itch due to vulval engorgement. There is also an increased risk of vaginal discharge and thrush during pregnancy, which may cause itch.
- Breast-feeding can cause itch due to low oestrogen levels.
- Any cause of a generalised body itch may also cause itching of the vulva. For example, a generalised body itch may be a side-effect of some medicines or due to some blood disorders, thyroid problems or kidney or liver disease.
- Diabetes can cause itch in the vulval area.
- A cancer of the vulval skin is an uncommon cause.
In some cases, no cause can be found. Some women examine their vulval region using a mirror to look for changes. However, since there are so many conditions that have vulval itching as a symptom the only real way to find an answer/treatment (if indicated) is by having a thorough medical examination.
