What does yellow discharge mean?

Yellow discharge can be normal or a sign of irritation or infection, depending on its colour, smell, and whether there are other symptoms.

Light yellow discharge without pain or odour is often harmless, while darker, strong-smelling, or irritating discharge should be checked by a doctor.

For parents, noticing yellow discharge can be worrying, especially in children or early teens. 

But in many cases it’s linked to normal body changes or mild irritation. Understanding what’s typical helps you know when to monitor and when to seek medical advice.

What causes yellow discharge?

Yellow discharge can be caused by a range of factors, from normal body processes to mild infections. 

The likely cause depends on the shade of yellow, how long it lasts, and whether other symptoms are present.

Common causes include:

• Normal discharge: dried discharge can appear light yellow on underwear or panty liners
• Hormonal changes: discharge often increases at certain points in the menstrual cycle
• Vulvovaginitis: mild inflammation or irritation caused by bacteria, yeast, soaps, tight clothing, or moisture
• Other infections: urinary tract or bacterial infections can sometimes affect discharge
• Sexually transmitted infections: uncommon in children and younger teens, but possible in older adolescents and usually linked with pain or strong odour

If discharge appears more brown or like it’s turning brown, or changes around the menstrual cycle, learning about brown discharge can help explain what’s happening.

Is yellow discharge normal during puberty?

Yes, mild yellow or off-white discharge can be normal during puberty as the body starts producing more vaginal secretions. 

This type of discharge is usually light in colour, not strong-smelling, and not painful.

Normal pubertal discharge often:

• appears gradually
• varies from day to day
• has little or no odour
• increases before a period

Tracking these changes over time can help teens learn what’s normal for their body and help parents spot changes that may need checking. We also have a deep dive on discharge before a period if this is helpful!

Can younger children have yellow discharge?

Yes, yellow discharge can also occur in younger children and is often related to irritation or vulvovaginitis rather than hormones. 

This is relatively common and usually manageable with gentle care.

In younger children, discharge may be linked to:

• sensitive skin
• bubble baths or scented products
• tight clothing or poor airflow
• moisture being trapped in the area
• wiping habits

Green, grey, or foul-smelling discharge in children should always be checked by a healthcare professional.

When should parents worry about yellow discharge?

Parents should seek medical advice if yellow discharge comes with other symptoms that suggest infection or ongoing irritation.

It’s best to speak to a doctor if your child or teen has:

• a strong or unpleasant odour
• itching, burning, or redness
• pain when urinating
• discharge that lasts more than a few days
• green or grey discharge
• fever or signs of being unwell

Early assessment can provide reassurance and help rule out infection.

How is vulvovaginitis treated in children?

Vulvovaginitis in children is usually treated by reducing irritation and supporting gentle hygiene. In some cases, a doctor may recommend medication if an infection is present.

Supportive care often includes:

• washing with warm water and mild, fragrance-free soap
• avoiding bubble baths, scented wipes, and harsh detergents
• wearing loose, breathable cotton underwear
• changing underwear regularly
• keeping the area clean and dry

If your child uses liners, it can help to understand whether panty liners are good for regular use or whether they may increase moisture and irritation.

Can tracking discharge help families understand what’s normal?

Yes, paying attention to discharge colour, timing, and other symptoms can help parents and teens understand what’s normal and recognise changes earlier. Tracking can also be useful information to share with a healthcare professional.

Tracking helps families:

• notice patterns linked to the menstrual cycle
• understand why discharge changes at different times
• feel more confident about when to seek help

For teens who menstruate, tracking discharge alongside cycle changes can make it easier to understand signs of when a teen’s next period might be coming.

What should parents remember about yellow discharge?

Yellow discharge is often normal, especially when it is light in colour and not accompanied by pain or odour. 

Watching for changes, supporting gentle hygiene, and knowing when to seek medical advice can help keep children and teens healthy and reassured.

Most importantly, discharge is a normal body function. 

Calm, open conversations help children and teens feel comfortable asking questions and understanding their bodies as they grow.
