Vaginal discharge change what it can mean

Overview

Vaginal discharge is fluid that comes from the vagina. It is normal for most women and people with vaginas. A change in colour, smell, thickness or amount can happen for many reasons – some harmless, some needing medical attention.

Yes. Almost every woman and person with a vagina will notice changes in discharge at some point in their life.

Anyone who has a vagina – from young girls to older women. Changes are most common during the reproductive years, but can also occur after menopause.

Symptoms

Common symptoms

• Change in colour – white, yellow, green, grey or brown
• Change in smell – fishy, musty or different from usual
• Change in texture – frothy, thick like cottage cheese, watery or sticky
• Change in amount – much more or much less than typical
• Itching or irritation around the vulva
• Burning when urinating (peeing)
• Soreness or redness
• Pain during sex
• Spotting or bleeding between periods (after having ruled out other causes)

Symptoms in children

• Any vaginal discharge in a girl who has not yet started her periods should be checked by a doctor.
• Signs to watch for: redness, itching, pain when peeing, or discharge that is yellow, green or bloody.

Symptoms in older adults

• After menopause, discharge often becomes thinner and less. Changes may be due to vaginal dryness or infection.
• Bleeding after menopause together with discharge always needs urgent medical review.
• Thin, watery discharge or spotting can also be a sign of something more serious, so always check with a doctor.

Causes

Main causes

• Hormone changes – during menstrual cycle, pregnancy, menopause
• Bacterial vaginosis (BV) – an imbalance of normal bacteria in the vagina
• Thrush (candidiasis) – a fungal infection that causes thick white discharge and itching
• Sexually transmitted infections (STIs) – like chlamydia, gonorrhoea, trichomoniasis
• Irritation from soaps, laundry detergents, perfumed products or tight clothing
• Retained foreign object – like a tampon left in too long
• Cervical or vaginal conditions – including polyps or (rarely) cancer

Risk factors

• Being sexually active – especially with new or multiple partners
• Using antibiotics – they can upset the balance of bacteria in the vagina
• Douching or using vaginal deodorants – these can irritate the vagina
• Having diabetes – high blood sugar can increase the risk of thrush
• Using spermicide or certain lubricants
• Wearing synthetic, tight underwear that traps moisture
• Weakened immune system – from illness or medications

When to see a doctor

See a doctor urgently if:

• Discharge that is green, yellow, or has blood
• Pain in your lower belly or pelvis
• Fever with discharge
• If you are pregnant and notice any sudden change in discharge
• If you think you may have an STI

Book a routine appointment if:

• Mild change in colour or smell that does not go away after a few days
• Itching or irritation without severe pain
• Discharge that is white and thick (like cottage cheese) with mild itch – may be thrush, can be treated with over‑the‑counter cream but see doctor if not sure
• Recurrent changes that keep coming back

Diagnosis

Your doctor will ask about your symptoms, sexual history and any recent changes. They may do a gentle internal examination (pelvic exam).

Tests that may be done

• Swab test – a small cotton bud is used to take a sample of discharge for analysis
• Urine test – to check for infections including STIs
• Blood test – if needed to check for STIs or other conditions
• pH test – a simple test to see if the vagina is too alkaline (common in BV)

What to expect at your appointment

The examination is usually quick and not painful. You can ask for a chaperone (another staff member) to be present. Results from a swab may take a few days. You may be asked to avoid sexual intercourse and douching for 24‑48 hours before the test.

Treatment

Treatment depends on the cause. Many changes in discharge do not need any treatment. If an infection is found, it can usually be treated with antibiotics or antifungal medication. It is important to complete the full course even if symptoms improve.

Self-care at home

• Avoid using soaps, shower gels or perfumed products near the vagina – just warm water is enough
• Wear cotton underwear and avoid tight synthetic clothing
• Change out of wet or sweaty clothing quickly
• If you think it might be thrush, you can try an over‑the‑counter antifungal cream – but see a doctor if you are not sure or if symptoms come back
• Do not douche – it upsets the natural balance and can make things worse

Medical treatments

For bacterial vaginosis, your doctor may prescribe antibiotic tablets or vaginal cream. For thrush, antifungal tablets or creams are common. For STIs like chlamydia or gonorrhoea, antibiotics are given, often in a single dose or a short course. Your partner(s) may also need treatment to avoid reinfection.

When is surgery considered?

Surgery is very rarely needed. It might be considered if a polyp or other growth in the cervix or vagina is causing the discharge, or if cancer is detected.

Living with this condition

Most changes in discharge are temporary and go away with treatment or on their own. You can continue your normal activities. If you have an infection, avoid sex until you have finished treatment and symptoms have gone.

Lifestyle tips

• Wear breathable cotton underwear
• Avoid using scented pads or panty liners
• Wipe from front to back after going to the toilet
• Stay hydrated – drinking water helps overall health
• If you have diabetes, keep your blood sugar under control to reduce the risk of thrush

Diet and exercise

A balanced diet rich in fruits, vegetables and whole grains supports your immune system. Some people find that eating plain yoghurt with live cultures helps maintain healthy vaginal bacteria, but there is no strong proof. Regular exercise helps overall wellbeing.

Mental health and emotional wellbeing

Changes in discharge can cause worry, embarrassment or affect your relationship and sex life. It is normal to feel anxious. Remember that most causes are treatable. Talking to your doctor or a trusted friend can help.

Prevention

You cannot prevent all changes, but you can reduce the risk of infections. Good hygiene (gentle, not over‑cleaning), safe sex (using condoms), and avoiding irritants help. Do not douche. Wearing cotton underwear and avoiding tight clothing also helps keep the area healthy.

Screening programmes

If you are sexually active and under 25 in the UK, you are offered chlamydia screening. Regular cervical screening (smear test) can detect changes that might cause discharge. Speak to your GP about what checks are right for you.

Complications

If left untreated

• Untreated STIs can lead to pelvic inflammatory disease (PID), which may cause long‑term pain and fertility problems
• Bacterial vaginosis during pregnancy increases the risk of premature birth
• Chronic thrush can cause recurring discomfort and skin damage
• Rarely, persistent abnormal discharge (especially with bleeding) could be a sign of cervical or vaginal cancer

Long-term outlook

For most people, the outlook is excellent. With proper diagnosis and treatment, infections clear up quickly and discharge returns to normal. Even if a serious cause is found, early treatment gives the best chance of a good outcome. Do not delay getting help – most changes are simple to fix.
