Vaginal Dysbiosis: Getting Thrown Off Balance

Your vaginal microbiome is a delicate ecosystem. When it’s in balance and thriving, it protects you from infection and supports your overall health. But when that careful balance is disrupted, it can’t function the way it’s supposed to, leading to a whole host of challenges.

Vaginal Dysbiosis: Getting Thrown Off Balance

Your vaginal microbiome is a delicate ecosystem. When it’s in balance and thriving, it protects you from infection and supports your overall health. But when that careful balance is disrupted, it can’t function the way it’s supposed to, leading to a whole host of challenges.

In this article, we’ll explore vaginal dysbiosis; what causes it, how it impacts your health and tips on how to maintain a healthy vaginal microbiome.

What Is Vaginal Dysbiosis?

Vaginal dysbiosis is when the natural balance of your vaginal microbiome is thrown off. 

Your vaginal microbiome is a diverse community made up of trillions of bacteria, fungi and microorganisms. Your microbiome is your vagina’s natural defence mechanism against infection. However, your vaginal microbiome is highly sensitive and can easily slip out of balance. 

Think of your microbiome as a bustling city, with good bacteria, harmful bacteria, and fungi all living together. When everything’s in balance, the city runs smoothly. But when one species overtakes the others, it’s like a mob causing chaos. This chaos shows up in the form of vaginal infections, discomfort, a change in discharge and a higher risk of sexually transmitted infections (STIs). 

What’s Throwing My Vagina Off Balance?

Many factors can disrupt the delicate balance of your vaginal microbiome. Understanding these causes is the first and most important step to keeping your vagina healthy and preventing dysbiosis. 

Here are some of the most common factors:

1. Hormonal Changes

Hormonal fluctuations are one of the biggest contributors to dysbiosis. Menstrual cycles, pregnancy, and menopause all cause changes in oestrogen levels, which directly affect the vaginal microbiome. 

Higher oestrogen levels promote the growth of lactobacilli, the helpful bacteria that keep the vagina healthy. However, too much oestrogen can also trigger overgrowth of candida, leading to vulvovaginal candidosis (VVC) (also known as yeast infections or thrush). Lower oestrogen levels during breastfeeding and menopause lead to lower lactobacilli levels, enabling the overgrowth of harmful bacteria and conditions like recurrent BV.

2. Lifestyle Habits

Your daily habits can also have a big impact on your vaginal microbiome. These include:

3. External Factors

Certain external factors may also impact the balance of bacteria in your vagina:

  • IUD Use: A small study found that copper IUDs may increase inflammation in some women, leading to a 5.5-fold increase in total bacteria and decreasing Lactobacilli levels. 

  • Over-Cleaning: Your vagina is self-cleaning. Washing intimate areas with harsh soaps, sprays, wipes, or douching can do more harm than good by disrupting your natural pH levels and removing healthy mucus.

4. Antibiotics

Antibiotics are often necessary to treat bacterial infections, like BV. The problem is that antibiotics don’t discriminate: they also attack beneficial bacteria like Lactobacilli

Have you ever gotten a yeast infection while taking antibiotics or soon after? That’s because low Lactobacilli levels allow harmful microorganisms like Candida to overgrow, leading to infections like Vulvo Vaginal Candida (thrush, or yeast infections). 

Top tip: only use antibiotics when prescribed by a doctor and consider boosting your prebiotic and probiotic intake through foods rich in these to help maintain your microbiome balance during treatment. For example, fermented foods like kefir, sauerkraut and kimchi contain probiotics, while onions and garlic are rich in prebiotics. 

5. Genetics

Genetics play a significant role in the makeup of your vaginal microbiome. Studies have shown that women from different parts of the world have different microbial profiles

Women from North America, Japan, and Europe tend to have more Lactobacilli in their microbiomes, while women from African and Hispanic backgrounds often have a wider mix of bacteria and fewer Lactobacilli. These differences can affect the risk of dysbiosis

Signs of Vaginal Dysbiosis 

When your vaginal microbiome is out of balance, it can leave you more vulnerable to infection. If you’re getting repeated infections, it could be a sign that you have vaginal dysbiosis.

Some of the most common issues include: 

  • Bacterial Vaginosis (BV): a condition where the number of Lactobacilli drops, and harmful bacteria take over. BV can cause symptoms like grey discharge, a fishy odour, and itching.

  • Yeast Infections (VVC): When Candida species overgrow, they can lead to itching, burning, and thick, white discharge.

  • Increased Risk of STIs: An imbalanced microbiome can make you more susceptible to sexually transmitted infections (STIs) if not using barrier contraception.

How to Avoid Vaginal Imbalance

Avoiding vaginal dysbiosis is all about maintaining a healthy balance in your vaginal microbiome. Here are some practical tips to keep things in check:

  • Turn to Science: Don’t fall for common myths about vaginal health. Try to avoid unverified advice on social media and stick to reliable, science-backed sources.

  • Use Water: Avoid douching or cleaning your vulva or vaginal area with anything other than water.

  • Eat Well: A diet rich in vitamins, minerals, and fibre can all support a healthy microbiome.

  • Manage Stress: Find ways that work for you to manage stress. Rest, exercise, meditation, or hobbies can all help to keep your immune system functioning properly.

  • Get Support: If you notice unusual symptoms like abnormal discharge, odour, itching, burning or soreness it’s important to consult a healthcare provider. Catching the issue early is your best bet at preventing more serious issues.

Restoring Your Balance 

Vaginal dysbiosis can be confusing and frustrating, but understanding just how delicate your vaginal microbiome is, is the vital first step toward restoring balance. By knowing what can disrupt it, recognising the signs of imbalance and learning how to support a healthy vaginal microbiome, you can take proactive steps to keep your vaginal health on track.

Caring for your vaginal health isn’t always a walk in the park. But with the right information and support, you can take control of your balance and reclaim your equilibrium.
