Vaginal thrush (also called a vaginal yeast infection) occurs when the balance of fungi in the vaginal flora is disrupted. Although it is usually mild, it can be uncomfortable for those affected. Understanding the causes and symptoms of this common infection is a useful first step towards managing it. Let's look at the triggers and the signs of vaginal thrush.

What Is a Vaginal Yeast Infection?

The vaginal thrush, also known as candidiasis, is a common and generally benign fungal infection in women. In France, three in four women experience a vaginal yeast infection at some point in their adult lives. Vaginal thrush occurs when an imbalance in the microbiota leads to excessive overgrowth of the fungus Candida albicans, which is naturally present in the vagina.

Why Does Vaginal Thrush Happen? What Causes It?

Several factors can contribute to a vaginal yeast infection. These are some of the most common causes:

Hormonal changes: Hormonal fluctuations, particularly in oestrogen and progesterone, can create conditions conducive to the growth of Candida albicans. A yeast infection may therefore be more likely around the time of a period, during pregnancy or around menopause. 

Antibiotics: Antibiotics can disrupt the balance of the vaginal microbiota by eliminating beneficial bacteria essential for maintaining a healthy flora. 

A weakened immune system: When the immune system is weakened, the body becomes more prone to developing fungal infections. Certain medical conditions or immunosuppressive drugs can therefore lead to vaginal yeast infections. 

Harsh intimate hygiene products: Unsuitable intimate hygiene practices can disrupt the vaginal balance. Vaginal douching, excessive washing, or harsh cleansing products (containing preservatives, fragrances, etc.) may contribute to a yeast infection.

Stress: Some studies suggest that stress is directly linked to the excessive proliferation of pathogenic microorganisms, such as the yeast Candida albicans. A highly stressful lifestyle can therefore create conditions conducive to the development of vaginal yeast infections.

What Are the Symptoms of Vulval Thrush?

A yeast infection can cause several symptoms, which vary from person to person. These are some of the most common signs of vaginal thrush:

  • Itching 

  • A burning sensation 

  • Redness 

  • Unusual vaginal discharge

  • Swelling of the vulva 

  • Discomfort during sex

  • Soreness or dryness

Please note that only your GP can assess these symptoms and make a reliable diagnosis.

What Are the Natural Ways to Ease the Symptoms of Vaginal Thrush?

Vaginal yeast infections can be uncomfortable for those affected. However, natural solutions can relieve yeast infection symptoms and restore balance.

A Bicarbonate of Soda Sitz Bath

Sodium bicarbonate is often used to relieve the symptoms of a vaginal yeast infection. When pathogenic microorganisms proliferate within the vaginal flora, the pH of the intimate area is altered. Bicarbonate of soda helps to alkalise the vulvar area and neutralise acidity, thereby creating an environment less conducive to the growth of Candida albicans.

The added bonus? Bicarbonate has soothing properties that help reduce itching and redness associated with a vaginal yeast infection.

To enjoy the benefits of bicarbonate of soda, nothing beats a soothing sitz bath! Here’s how to do it:

  • Fill your bath with lukewarm water.

  • Add a small cup of bicarbonate of soda to the bath water. 

  • Make sure the bicarbonate of soda is thoroughly dissolved in the bathwater. 

  • Sit in the bath, making sure your genital area is completely submerged in the water. 

  • Soak for about 15 minutes.

  • Dry your genital area thoroughly with a clean terry towel (this towel must not be reused until it has been washed).

Repeat step once or twice a day until your symptoms improve.

Rinsing with Apple Cider Vinegar

Apple cider vinegar is a valuable ally in soothing the symptoms associated with vaginal yeast infections in women. Apple cider vinegar is known for its antifungal properties. It can also help restore a balanced pH in the vaginal area and promote an environment conducive to the growth of beneficial bacteria. 

To reap the benefits of apple cider vinegar, try using it as a rinse. After your shower, finish with a rinse made with 200 ml of lukewarm water and 2 tablespoons of unpasteurised cider vinegar. Then dry your genital area thoroughly before getting dressed.

Using a Mild Soap

Using gentle intimate hygiene products is essential to prevent and soothe vaginal yeast infections. To maintain the balance of the vaginal microbiota, use only water and pH-neutral intimate hygiene products guaranteed to be free of fragrances and preservatives. Here are our tips for choosing your intimate hygiene soap: 

  1. Choose a soap with a pH between 3.8 and 4.5, specifically designed for intimate hygiene (available from pharmacies or health food shops).

  2. Choose a product guaranteed to be free from harsh chemicals. Read the ingredients list carefully.

  3. Opt for gentle, natural active ingredients, derived from soothing plant extracts such as chamomile (Chamaemelum nobile) or aloe vera (Aloe barbadensis).

  4. Avoid antibacterial soaps, as they are too harsh for the sensitive vaginal flora.

Taking Probiotics

Probiotics may help restore the balance of the vaginal flora. When the vaginal microbiota is weakened, the environment becomes more conducive to fungal growth. Beneficial bacteria may not be present in sufficient quantities to protect the area from pathogen proliferation. To relieve a vaginal yeast infection naturally, consider taking a dietary supplement containing probiotics. Ask your pharmacist for advice on finding the bacterial strains best suited to your needs!

Expert Advice

Genital thrush is a common local imbalance. A whole-body approach may help support the vaginal microbiota over the long term. Diet, stress management, sleep, and other lifestyle factors may help create conditions that favour beneficial bacteria in the vaginal area.
