What You Can Do About Strong Vaginal Odour

by | Jun 18, 2020 | Women's Health | 2 comments

Despite the unrealistic social expectations placed upon women, your vagina is never going to smell like roses. If it ever does, a visit to your GP is definitely on the cards!

Strong or unusual vaginal odour is often accompanied by a change in discharge. It’s completely normal to have clear or white discharge that changes throughout your monthly cycle. Sometimes, it’ll dry to a slight yellow colour in your underwear.

However, normal vaginal discharge shouldn’t generally bother you. If a curious odour is obvious for more than a few days or is noticeably strong, you may have something going on downstairs. Women sometimes describe the odd smell as a fishy odour, yeasty, ammonia-like or even metallic.

When accompanied by vaginal discomfort, itching, or a change in the colour or amount of discharge compared to normal, you can be almost certain something is amiss.

Your vagina does an excellent job taking care of itself. With a healthy pH (acidity) level between 3.8 and 4.5, it will self-clean while fighting-off nasty, odour-causing bacteria.

On the other hand, problems can start to occur if the balance of pH, bacteria and yeast is interrupted.

What Can Cause an Unusual Vaginal Odour?

There are lots of reasons for a persistently smelly vagina. Here are a few of the most common.


Bacterial vaginosis (BV) is the most common vaginal infection affecting women aged 15 to 44.

It’s caused by a bacterial imbalance in the vagina, with a reduction of the ‘good’ vaginal bacteria (lactobacillus) and an overgrowth of the ‘bad’ Gardnerella bacteria. The latter is commonly found at lower levels in the vagina.

Typical symptoms include a fishy odour and grey or watery vaginal discharge.


Most GPs have removed tampons forgotten from previous menstrual cycles. Women are often unnecessarily mortified when this happens. I reassure them that they’re only human with busy lives full of distractions.

Once you’ve had a tampon removed, it’s important to be alert to any ongoing vaginal discomfort or flu-like symptoms. Any abnormal odours or discharge should disappear after a few days. Please see your GP if your symptoms don’t improve.


Trichomonas is an uncommon sexually transmitted infection that can result in a change in vaginal odour.

More common STI’s such as gonorrhoea or chlamydia don’t tend to cause a change in odour.

Tips on Genital Hygiene

Here are some great hygiene tips to consider practising as part of your routine.


Avoid washing your genital area with soap – especially inside the vagina. Warm water is fine. Most soaps, including scented body wash, and so called ‘feminine products’ can mess with the vagina’s natural acidity, helping ‘bad’ bacteria to flourish.

As semen and lubricants can interrupt your pH level while introducing bacteria, it’s wise to wash after sexual intercourse. I’m certainly not suggesting you ruin the mood by rushing into the shower; just have a good rinse when you can.


As your vagina is perfectly capable of cleaning itself, there’s no need for douches.

Douches are unnecessary products commonly marketed in the USA to ‘keep your vagina clean’. There’s no scientific evidence whatsoever for this claim.

Worse still, douching will likely wash away the good bacteria in your vagina. The result is often a compromised pH level, followed by unwanted infections and odours.


I implore you to avoid any products that suggest your vagina should smell like coconut vanilla pudding. The concept is utterly ridiculous.

Marketers play on the insecurities many women have towards their natural vaginal odour being off-putting. I find it offensive to infer women’s genitals are dirty and need to be freshened and perfumed.

Moreover, vaginal deodorisers are bad for you. They can unbalance your vaginal flora and create the kind of problems they claim to solve. Um, no thanks.


Cotton underwear is preferable to silk or polyester undies as it allows your undercarriage to breathe. Try to avoid dressing in tight pants or shorts whenever possible.

I don’t recommend wearing panty liners every day either. They can cause irritation to your genital skin.

It’s also a good idea to remove any wet clothes as soon as practical following swimming or exercise.

Some other hygiene tips:

  • Always wipe your vagina from front to back.
  • Take a shower after exercise or excessive sweating.
  • Don’t insert objects into your vagina that have been in your anus, such as sex toys.
  • To avoid a UTI, remember to urinate after intercourse.

When to Visit Your GP

You know your body better than anyone else. My advice? Follow your instincts. If you feel things aren’t quite right, skip the home remedies and over-the-counter treatments and get to your GP.

Indicators you may need to visit a doctor include:

  • an odour that seems to be getting stronger;
  • a persistent change in the colour or amount of vaginal discharge; or
  • itching or burning.

Your GP will usually take a detailed history, perform an examination and possibly collect a vaginal swab. If you don’t feel comfortable with having a GP take a swab, you can always self-collect in the clinic’s bathroom.

Some vaginal infections, such as bacterial vaginosis can be treated with internal creams and gels. STI’s such as trichomonas might require tablet antibiotics.

It’s best to avoid over-the-counter products such as the Vagisil and Femfresh range as they can do more harm than good. Studies have shown such products impact on lactobacillus growth – the good bacteria living in your vagina.

If any of the above indicators are present, please don’t delay seeing a GP. Infections that aren’t adequately treated can cause further complications with your pelvic area and even lead to infertility.

    I have a friend who has the problem of bad odour in the vagina but am afraid of telling her what should I do to help her

      Hi Scara,

      Telling a friend that they have bad odour of any kind can be daunting. It’s also a very caring thing to do – a conversation most people would like a friend to have with them if they smelt.

      How you tell your friend depends on many factors, including how close you are to them, the right timing (e.g. not just before work or Uni), and their sensitivity to personal feedback.

      Overall, keeping the conversation short and to the point is generally best. You may want to consider these tips:

      – Speak to your friend in private.
      – Mention that you’re aware that this is an uncomfortable but necessary conversation.
      – Keep it between you and your friend – don’t say other people have also noticed an odour.
      – Point out to your friend that you’d like it if she did the same for you.
      – Let them respond.
      – Be respectful and offer practical suggestions, such as visiting their GP. Treatments for vagina odour are generally quite effective.

      Kind regards,
      Dr Elaine Sung
