Normal vaginal discharge helps keep the vagina healthy and can change across the cycle, pregnancy and sexual activity.
What to know
Bacterial vaginosis, candidiasis, trichomoniasis, cervicitis, sexually transmitted infections and irritation can cause overlapping symptoms.
Repeated use of unneeded antibiotics or antifungals can delay the correct diagnosis. Vaginal douching and inserting herbs or cleansing products can disturb the vaginal environment.
Key points
Discharge variesAmount and texture can change normally through the cycle.
Causes overlapSymptoms alone cannot reliably identify every infection.
Testing may helpSwabs, microscopy or STI testing may be appropriate.
Avoid internal cleansingThe vagina does not require douching or inserted products.
Signs and symptoms
Normal discharge can be clear or white and vary in amount and texture. Symptoms that are new, uncomfortable, persistent or linked with pain deserve assessment.
Odour or colour change
A strong fishy smell, yellow-green discharge, blood or a marked change from your normal pattern may indicate infection or another cause.
Itching and soreness
Vulval itching, swelling, cracks or burning can occur with candidiasis, irritation, skin conditions and some infections.
Pain or urinary symptoms
Pain during sex, pelvic pain or burning urination may point beyond a simple vaginal infection.
No symptoms
Bacterial vaginosis and sexually transmitted infections may cause few or no symptoms.
Causes and contributing factors
Vaginal symptoms are not a hygiene failure. They result from changes in microbes, infections, irritation, hormones, skin conditions or cervical and pelvic disease.
Bacterial vaginosisAn imbalance in vaginal bacteria can cause thin discharge and a strong odour; it is treatable.
CandidiasisYeast can cause intense itching, soreness and thick discharge, but these symptoms are not unique to yeast.
STIs and cervicitisTrichomoniasis, chlamydia, gonorrhoea and other infections may cause discharge, bleeding or pain and require partner considerations.
Irritation and low estrogenScented products, douching, inserted herbs, skin conditions, breastfeeding and menopause can cause irritation or dryness.
How healthcare professionals assess it
Assessment is individual. Not every person needs every test, and results must be interpreted alongside symptoms, history and examination findings.
Confidential history
A clinician asks about symptoms, pregnancy, medicines, products used, treatment attempts and sexual exposure.
Examination
External and speculum examination may identify inflammation, sores, cervical discharge or another source.
Vaginal testing
pH, microscopy, rapid tests or laboratory swabs may distinguish bacterial vaginosis, yeast and trichomoniasis.
STI and pregnancy testing
Urine, swab or blood tests and a pregnancy test may be appropriate based on history.
Treatment and management
Correct treatment depends on the cause. The same symptom can require an antibiotic, antifungal, STI treatment, skin treatment or no medicine.
Cause-specific medicine
Use the prescribed antibiotic, antifungal or other treatment for the diagnosed or clinically suspected cause.
Partner management
Some STIs require partners to be tested or treated; bacterial vaginosis and candidiasis are managed differently.
Gentle care
Wash the external vulva gently with water or a mild unscented product; avoid internal cleansing.
Reassessment
Persistent or recurrent symptoms need review rather than repeated unsupervised treatment.
Practical steps you can take
Avoid douching and inserting herbs, antiseptics, soap or deodorising products into the vagina.
Do not share antibiotics or repeatedly buy treatment based only on discharge appearance.
Use condoms or avoid sex as advised while an STI is being evaluated or treated.
Tell the clinician if you are pregnant, breastfeeding, diabetic or immunocompromised.
Seek urgent care for pelvic pain with fever, pregnancy, fainting or severe illness.
Questions to ask at an appointment
Writing questions down can make a consultation more useful, especially when symptoms are stressful or complex.
- Which causes are being considered, and do I need a swab or STI test?
- Should a partner be tested or treated?
- Could a product, medicine, pregnancy or menopause be contributing?
- What should I do if symptoms recur after treatment?
Common questions
Is all discharge an infection?
No. Normal discharge changes through the cycle, but a new odour, irritation, pain or colour change may need review.
Can I identify yeast by thick white discharge?
Not reliably. Several conditions overlap, especially when symptoms recur or treatment fails.
Does douching prevent odour or infection?
No. Douching can disturb protective vaginal bacteria and increase the risk of bacterial vaginosis.
