Vaginal and vulval itching is a common concern, yet many women still feel uncomfortable discussing it. In fact, itching in the intimate area is one of the reasons women seek gynaecological advice, particularly when symptoms become persistent or severe.
Vaginal itching can have several causes, including fungal infections, vulval skin conditions, hormonal changes and irritation. Identifying the underlying cause is essential, as different conditions require different treatments.
In this article, we explain the main causes of vaginal and vulval itching, the symptoms to look out for and the treatments available to help relieve discomfort.
What causes vaginal and vulval itching?
Before exploring the possible causes, it is important to understand the difference between the vagina and the vulva.
The vulva refers to the external genital structures, including the labia and clitoris, while the vagina is the internal canal connecting the vaginal opening to the cervix.
This distinction matters because certain conditions affect the external skin, while others involve the vagina or both areas.
1. Vulval lichen sclerosus
Vulval lichen sclerosus is a chronic inflammatory skin condition that can cause intense itching of the vulva.
It is sometimes mistaken for a fungal infection because both conditions can cause persistent discomfort.
However, lichen sclerosus is a distinct condition that requires specific medical treatment and long-term monitoring.
Unlike vaginal infections, lichen sclerosus primarily affects the skin of the vulva and surrounding genital area rather than the internal vaginal canal.
If left untreated, it may lead to changes in vulval anatomy, skin fragility and discomfort during sexual intercourse.
2. Fungal and bacterial infections
Infections are another common cause of vaginal and vulval itching.
Vaginal candidiasis, commonly known as thrush, is a fungal infection that can cause intense itching, irritation and redness.
Other symptoms may include:
- Thick, white vaginal discharge.
- Burning or soreness around the vaginal opening.
- Discomfort during sexual intercourse.
- Stinging when urine comes into contact with irritated skin.
Bacterial infections and changes in the vaginal microbiota can also cause discomfort, although symptoms vary depending on the condition.
For example, bacterial vaginosis is more commonly associated with thin discharge and an unpleasant odour than with intense itching.
Changes in vaginal discharge, odour or persistent irritation should be assessed by a healthcare professional to identify the cause.
3. Vulval dermatitis and irritation
Dermatitis is another possible cause of itching in the intimate area.
It occurs when the skin becomes inflamed, often following contact with irritating substances or allergens.
Common triggers include:
- Fragranced soaps and intimate hygiene products.
- Scented sanitary pads or panty liners.
- Laundry detergents and fabric softeners.
- Friction from tight-fitting clothing.
- Certain topical products or ingredients.
Vulval dermatitis may cause itching, redness, burning and increased skin sensitivity.
Identifying and avoiding the triggering substance is an important part of managing the condition.
4. Stress and emotional factors
Stress does not necessarily cause vaginal itching directly, but it can influence how the body responds to discomfort and inflammatory skin conditions.
In women with chronic vulval conditions, such as lichen sclerosus or dermatitis, periods of stress may coincide with increased itching or symptom flare-ups.
Persistent itching can also affect sleep, emotional wellbeing and quality of life, creating a cycle in which discomfort and stress reinforce one another.
For this reason, addressing emotional wellbeing may form part of a broader treatment approach, alongside appropriate medical care.
5. Hormonal changes and vaginal dryness
Hormonal fluctuations can affect the health of the vaginal and vulval tissues.
During menopause, declining oestrogen levels may cause the tissues to become thinner, less elastic and more sensitive.
These changes can contribute to vaginal dryness, itching, burning and discomfort during sexual intercourse.
Similar symptoms may occur after childbirth or during breastfeeding, when oestrogen levels can also be lower.
When these symptoms are associated with menopause, they may form part of genitourinary syndrome of menopause (GSM).
Symptoms of vulval itching caused by lichen sclerosus
Although several conditions can cause genital itching, persistent or intense vulval itching is one of the most characteristic symptoms of lichen sclerosus.
Other physical changes may also appear, particularly when the condition progresses without appropriate treatment.
One of the most recognisable signs of vulval lichen sclerosus is the appearance of white or pale patches on the external genital skin.
The affected areas may appear smooth, shiny or fragile, and the skin can become more vulnerable to small tears or fissures.
In some cases, changes in skin texture or elasticity may also develop.
These symptoms should be assessed by a specialist, as other vulval conditions can produce similar changes.
Dryness and skin fragility
Lichen sclerosus can make the vulval skin more fragile and susceptible to irritation.
Women may experience dryness, soreness or discomfort, particularly during physical activity or sexual intercourse.
However, vulval dryness associated with lichen sclerosus should be distinguished from vaginal dryness caused by hormonal changes.
Both conditions can coexist, particularly after menopause, but they require different approaches to treatment.
Changes in the labia minora and clitoral hood
When lichen sclerosus remains untreated or progresses over time, scarring can lead to changes in the structure of the vulva.
These changes may include:
- Gradual reduction or fusion of the labia minora.
- Scarring around the clitoral hood.
- Reduced elasticity of the vulval tissues.
- Narrowing of the vaginal opening.
In more advanced cases, narrowing of the vaginal opening may make penetration uncomfortable or difficult.
Early diagnosis and appropriate treatment are essential to help prevent scarring and preserve the normal structure and function of the vulva.
How to treat vaginal and vulval itching
The most appropriate treatment depends on the underlying cause of the itching.
Because several conditions can produce similar symptoms, it is important to obtain an accurate diagnosis before starting treatment.
Treatment for fungal infections
When itching is caused by vaginal candidiasis, antifungal medication is usually recommended.
Treatment may involve vaginal preparations, topical creams or oral medication, depending on the patient’s symptoms and medical history.
Many women begin to notice an improvement within a few days, although the time required for symptoms to resolve varies.
If infections recur frequently or symptoms persist despite treatment, further medical assessment may be necessary.
Treatment for vulval dermatitis
When itching is caused by dermatitis, treatment focuses on reducing inflammation and avoiding potential irritants.
Depending on the severity of the symptoms, a specialist may recommend:
- Stopping the use of fragranced intimate hygiene products.
- Using gentle, fragrance-free cleansers or water for external hygiene.
- Applying suitable emollients to protect the skin barrier.
- Using prescribed topical anti-inflammatory medication when necessary.
Maintaining a gentle intimate hygiene routine can help protect sensitive vulval skin and reduce irritation.
Treatment for vulval lichen sclerosus
High-potency topical corticosteroids are the established first-line treatment for vulval lichen sclerosus.
These medications help control inflammation, relieve itching and reduce the risk of progressive scarring.
Long-term medical follow-up is important because lichen sclerosus is a chronic condition that may require ongoing management.
Other approaches, including laser treatments, platelet-rich plasma and regenerative techniques using adipose-derived cells, have been investigated as potential treatments.
However, the available evidence is not sufficient to recommend these procedures as routine alternatives to established corticosteroid treatment.
Any additional treatment should be considered individually and discussed with a qualified specialist, taking into account its potential benefits, limitations and risks.
Treatment for vaginal dryness and hormonal changes
When itching is associated with hormonal changes, treatment may focus on restoring moisture and improving the comfort of the vaginal and vulval tissues.
Depending on the patient’s needs, options may include:
- Vaginal moisturisers.
- Lubricants to reduce discomfort during sexual intercourse.
- Local vaginal oestrogen therapy when clinically appropriate.
- Other prescribed treatments for genitourinary syndrome of menopause.
A personalised assessment can help determine whether symptoms are caused by hormonal changes, a skin condition or a combination of factors.
When should you see a gynaecologist for vaginal itching?
Occasional mild irritation may resolve once the triggering factor is removed. However, persistent, recurrent or severe itching should be medically assessed.
It is particularly important to seek advice if you notice:
- Itching that does not improve or repeatedly returns.
- White patches or changes in the appearance of the vulva.
- Unusual vaginal discharge or odour.
- Persistent burning or soreness.
- Skin fissures, sores or bleeding.
- Discomfort during sexual intercourse.
Not all vaginal or vulval itching is caused by an infection, and treating the wrong condition may delay an accurate diagnosis.
