Labial Adhesions

Overview

Labial adhesions (also called labial fusion) happen when the two small inner lips of a girl's genitals — called the labia minora — stick together. The skin joins in the middle, usually from the back toward the front, and can join a little or almost completely. It is not a wound or an injury. The joined skin is thin, pale and see-through, and it does not hurt in itself. It happens because the skin down there is very delicate and because young girls have very low levels of the hormone oestrogen (the female hormone), which normally keeps that skin smooth and separate.

Yes, it is common. It is one of the most frequent reasons parents bring a young girl to the doctor with a genital concern, and many family doctors and nurses see it regularly.

It mostly affects girls between about 3 months and 6 years old, because this is the age when oestrogen levels are lowest. It is uncommon in older girls and in adult women. It can occasionally happen after the menopause, when oestrogen levels fall again, or in people with long-term inflammatory skin conditions of the genital area.

Symptoms

Common symptoms

• No symptoms at all — the most common situation
• A thin, pale, see-through line or membrane joining the inner lips
• Urine dribbling slowly after a wee, or spraying instead of a single stream
• Urine collecting a little behind the joined skin and leaking later, which can dampen underwear
• Mild redness, soreness or itching around the genital area
• Irritation when wiping or during a nappy change

Symptoms in children

• Dribbling of urine after using the toilet or a wet patch in the pants shortly afterwards
• Nappy rash or redness that keeps coming back
• Occasional discomfort when weeing, or a wee that sprays upwards or sideways
• A child may seem completely untroubled — this is very common
• Rarely, a child may strain or seem to have trouble starting a wee

Symptoms in older adults

• This is rare in adults. When it happens after the menopause it is linked to low oestrogen and thinning, fragile skin
• Possible discomfort, itching or burning in the genital area
• Changes in the urine stream or difficulty keeping the area clean
• It can also be seen alongside long-term skin conditions of the vulva (the outer female genital area), which need a doctor's assessment

Causes

Main causes

• Low levels of oestrogen in early childhood, which makes the skin of the inner lips thin and easily irritated
• Irritation or inflammation of the skin that then heals by sticking together — this is the usual trigger
• Nappy rash, thrush or other skin irritation in the genital area
• Harsh soaps, bubble baths, scented wipes or detergents that irritate delicate skin
• Rarely, a shortage of vitamin D or certain skin conditions, which a doctor may consider

Risk factors

• Being a girl aged between 3 months and 6 years
• Frequent nappy rash or long-standing skin irritation in the genital area
• Eczema or other sensitive-skin conditions
• Using strong soaps, bubble baths or scented products on the genital area
• Nappies or underwear that keep the area warm and damp for long periods

When to see a doctor

See a doctor urgently if:

• Your child cannot pass urine, or is straining and in pain when trying
• Signs of a urine infection such as fever, pain when weeing or smelly urine
• Bleeding, discharge or a raw, weeping area
• The skin looks very red, swollen or sore, or your child is clearly in discomfort

Book a routine appointment if:

• You have noticed the inner lips appear joined, even if there are no symptoms — it is worth having it checked and confirmed
• Urine dribbling or damp underwear after weeing
• Repeated nappy rash or irritation in the genital area
• You are unsure what you are seeing and would like reassurance
• Your child is older than 6 to 7 years and the fusion has not started to separate

Diagnosis

A doctor or nurse will usually diagnose labial adhesions simply by looking at the area. They will gently part the outer lips to see the inner ones and check whether a thin, see-through membrane is joining them. This examination is quick and should not be painful. They will also ask about weeing, nappy rash, bowel habits and general health, and they will check the urine if an infection is possible.

Tests that may be done

• A gentle physical examination — this is usually all that is needed
• A urine sample test if there are symptoms such as burning or smelly urine, to rule out infection
• In most cases no other tests, scans or blood tests are required
• If the appearance is unusual or the condition comes back in an older girl or adult, a referral to a specialist may be suggested

What to expect at your appointment

The appointment is usually short and calm. The doctor will explain what they can see, check whether the opening for urine is clear, and ask whether your child has any symptoms. You can ask to stay close to your child throughout, and you can ask for a chaperone (a staff member present during the examination) if you would prefer. Most families leave with simple advice and no treatment at all.

Treatment

Treatment depends on whether the adhesions are causing any problems. If your child is weeing normally and has no pain or infections, the usual approach is to leave things alone and keep the area clean and protected — many adhesions separate on their own over months or years. If symptoms are troublesome, a doctor may suggest a prescribed cream, a protective ointment, or a gentle separation procedure. Your doctor will discuss the options and what suits your child.

Self-care at home

• Wash the genital area gently with plain warm water only — no soap, bubble bath or scented wipes
• Pat dry gently from front to back rather than rubbing
• Change nappies often and give the area time without a nappy when you can, so it stays dry
• Ask your doctor or pharmacist about a plain protective barrier ointment to reduce irritation
• Dress your child in loose cotton underwear and avoid tight clothing
• Never try to pull or stretch the joined skin apart yourself
• Keep up good fluid intake and treat constipation, as a full bowel can make weeing harder
• Go back to your doctor if weeing becomes difficult

Medical treatments

If treatment is needed, doctors often prescribe a cream containing a low dose of the hormone oestrogen, which is applied to the joined line for a short period; this helps the skin separate in many children. Because it is a hormone cream, it is only used when a doctor recommends it, and they will explain how to apply it, how long to use it and what to watch for. A plain protective ointment may also be suggested to reduce irritation. If a urine infection is found, it will be treated appropriately. Your doctor or pharmacist can answer questions about any treatment, and you should always follow their instructions rather than advice from the internet.

When is surgery considered?

Surgery is rarely needed. A doctor may suggest a gentle separation procedure if urine cannot drain properly, if there are repeated urine infections, or if a prescribed cream has not helped. This is usually a quick procedure done by an experienced clinician, often with a numbing gel or cream, and sometimes in a specialist clinic. Occasionally a small procedure under anaesthetic is needed. Your doctor will explain the benefits and risks, including the chance that the adhesions can come back, and will only recommend it when it is clearly in your child's best interests.

Living with this condition

For most families, life carries on exactly as normal. Your child does not need to be treated differently, and there is no need to check the area every day unless your doctor has asked you to. Focus on gentle washing, keeping the area dry, and noticing whether weeing is comfortable. If you use a prescribed cream, build it into a simple routine, such as after a bath, so it does not become a battle.

Lifestyle tips

• Keep bath times simple: plain water, no bubbles or perfumed products
• Choose cotton underwear and change it daily
• Encourage your child to wee regularly and not hold on
• Offer plenty of drinks through the day, and treat constipation early with advice from your doctor
• Teach gentle wiping from front to back
• Avoid scented wipes, powders and sprays in the genital area

Diet and exercise

No special diet is needed. Drinking enough fluid helps keep urine dilute and reduces irritation, and eating fibre-rich foods helps prevent constipation, which can make weeing uncomfortable. Normal play, running around and swimming are all fine — there is no reason to limit activity, and swimming pools do not make the condition worse.

Mental health and emotional wellbeing

Parents often feel worried, and sometimes guilty, when they notice something unusual in their child's genital area. Those feelings are very common and understandable, and it can help to talk them through with your doctor, who can reassure you. Children themselves are usually not bothered at all, especially when there are no symptoms. If your child is old enough to notice and feels anxious or embarrassed, keep explanations simple and calm, and let them know it is common and not their fault. If worry is affecting your sleep, mood or daily life, speak to your doctor — support is available, and you do not have to cope alone.

Prevention

You cannot completely prevent labial adhesions, because they are linked to the normal low oestrogen levels of early childhood. However, reducing irritation to the delicate skin may lower the chance of it happening or coming back. Gentle washing with water only, avoiding bubble baths and scented products, changing nappies promptly and treating nappy rash early are all sensible steps.

Screening programmes

There is no screening programme for labial adhesions. They are usually found during a routine examination or when a parent notices them. Regular check-ups for your child are a good opportunity to raise any questions.

Complications

If left untreated

• In many cases nothing happens at all — the adhesions simply separate over time
• Urine may pool behind the joined skin, causing dribbling, dampness and skin irritation
• Repeated urine infections can occur, which need treatment
• Rarely, urine cannot pass at all — this is an emergency and needs immediate medical care
• Rarely, a collection of urine can build up inside the vagina and cause discomfort or discharge

Long-term outlook

The outlook is very good. Most labial adhesions get better on their own as oestrogen levels rise, and they usually cause no lasting problems. Even when treatment is needed, it is simple and effective for most children, and serious complications are uncommon. Some children do get adhesions again after treatment, but they can usually be managed in the same way. If you have any worries at any point, your doctor is there to help.
