Vaginal itching: common causes, safe home care and when to worry

In short: Vaginal itching is very common and is usually caused by a yeast infection, bacterial vaginosis, or irritation from soaps, pads, sweat or shaving. Less often it is a sexually transmitted infection, low oestrogen after menopause or a skin condition. Keep the area clean with plain water and wear cotton underwear, but don't put home remedies inside the vagina. See a gynaecologist if itching lasts more than a few days, keeps coming back, or comes with unusual discharge.

Itching down there can be so uncomfortable, and so embarrassing to talk about. You may scratch at night, feel awkward at work, and not know whom to ask. Please know you are not alone. Almost every woman has this at some point.

The good news is that most causes are easy for a doctor to treat. Let's look at what might be going on.

Vaginal itching reason: the common causes

Yeast infection (thrush). The most common cause of itching. A yeast that normally lives in the vagina grows too much. You may notice thick, white, lumpy discharge, burning and redness.

Bacterial vaginosis (BV). An imbalance of the normal bacteria. It usually causes thin, grey-white discharge with a fishy smell. Itching is often mild.

Irritation (contact dermatitis). Scented soaps, intimate washes, bubble baths, detergents, perfumed pads or wipes, tight synthetic clothes, and shaving or waxing can all irritate the delicate skin.

Sweat and moisture. Hot, humid weather, long hours sitting, and damp underwear or pads left on too long can cause itching and rashes.

Sexually transmitted infections. Trichomonas, herpes and others can cause itching, sores, pain or unusual discharge.

Low oestrogen. After menopause, or while breastfeeding, the vaginal skin becomes thinner and drier, which can itch or burn.

Skin conditions. Eczema, psoriasis and a condition called lichen sclerosus (white, thin, itchy patches on the vulva) can affect this area too.

Vaginal itching and white discharge

When itching comes with discharge, the type of discharge gives a clue:

• Thick, white, lumpy, no strong smell: often a yeast infection.
• Thin, grey, fishy smell: often BV.
• Yellow or green, frothy, bad smell: possibly trichomonas or another infection.
• Normal discharge but itchy skin: often irritation, sweat or a skin problem.

These are only clues. The same symptoms can come from different causes, which is why a quick check by a doctor is better than guessing.

Yeast infection causes: why it happens

Yeast grows too much when the natural balance in the vagina is upset. This is more likely:

• After a course of treatment for another infection, which can kill off the good bacteria
• With high blood sugar or uncontrolled diabetes
• In pregnancy, because of higher hormone levels
• When the area stays warm and damp for long
• With a weak immune system
• Around your period, for some women; see yeast infections and bacterial vaginosis during menstruation

A yeast infection is not a sign of being "unclean", and it is not usually passed on through sex.

Vaginal itching during pregnancy

Itching in pregnancy is common, mostly because yeast infections happen more easily. Discharge also increases in pregnancy; read the truth about increased vaginal discharge in pregnancy. But please don't treat yourself in pregnancy, even with something you have used before. Some treatments are not right in pregnancy, and some infections like BV need care because they can affect the pregnancy.

Tell your doctor about any itching, smelly or coloured discharge, or burning while passing urine. Also mention it if you have intense itching on your palms and soles, especially in later pregnancy, as this needs a separate check.

Vaginal itching home remedies: what is safe

Gentle care can ease mild irritation and help prevent it coming back:

• Wash the outer area once or twice a day with plain water. Avoid scented soaps, intimate washes and sprays.
• Pat dry gently with a clean, soft towel.
• Wear loose cotton underwear and change it daily, or more often in hot weather.
• Change pads or liners every 4 to 6 hours, and don't use scented ones.
• Remove wet swimwear or sweaty gym clothes soon.
• Wipe from front to back.
• Avoid scratching; a cool, clean cloth on the outside can calm the itch.
• If you have diabetes, keep your blood sugar under control.

What not to do. Don't put curd, garlic, tea tree oil, vinegar, coconut oil or any other home remedy inside the vagina. These can irritate the skin, upset the natural balance and make things worse. Don't douche. And don't keep treating yourself again and again for "yeast". If itching keeps returning, it may be something else entirely.

When to see a gynaecologist

See a doctor if:

• Itching lasts more than a few days or keeps coming back
• You have unusual discharge, a bad smell, sores, blisters or lumps
• It hurts when you pass urine or have sex
• You see white patches or thinning skin on the vulva
• You are pregnant
• You have gone through menopause and have itching or dryness
• You think you may have been exposed to an infection through sex

A gynaecologist will usually ask a few questions, look gently at the area and may take a swab of the discharge. A urine or blood sugar test may be done too. Once the cause is known, a doctor can treat this easily.

Go to a doctor the same day if:

• You have fever with pelvic or lower tummy pain
• Foul-smelling discharge comes with fever or feeling unwell
• You have severe or one-sided tummy pain
• You are pregnant and have bleeding, tummy pain or a leak of watery fluid
• You have painful sores or swelling that makes it hard to pass urine

Questions women ask

What is the reason for vaginal itching?

The most common reasons are a yeast infection, bacterial vaginosis, and irritation from soaps, pads, sweat or shaving. Sexually transmitted infections, low oestrogen after menopause and skin conditions can also cause itching. A gynaecologist can find the exact cause with a simple check.

What does vaginal itching with white discharge mean?

Itching with thick, white, lumpy discharge is often a yeast infection. Thin, grey discharge with a fishy smell suggests BV. Yellow or green discharge may be another infection. Because these can look alike, see a doctor to know for sure.

What are the symptoms of a vaginal infection?

Common signs are itching, burning, redness or swelling, discharge that has changed colour, texture or smell, and pain while passing urine or during sex. Some infections cause few symptoms, so regular check-ups help.

Is vaginal itching during pregnancy normal?

It is common, often because yeast infections are more likely in pregnancy. But always tell your doctor rather than treating it yourself, as some infections need special care in pregnancy. Itchy palms and soles in later pregnancy also need a check.

Are home remedies safe for vaginal itching?

Simple care like washing with plain water, wearing cotton underwear and changing pads often is safe. Don't put curd, garlic, oils or anything else inside the vagina, as this can make things worse. If itching lasts more than a few days, see a gynaecologist.
