Let's talk about the vaginal microbiome

Updated: Nov 16

How healthy is your vagina? Do you regularly have bouts of vaginal burning or itching? Are you worried about odour or discharge?

If you have recurrent vaginal symptoms you will benefit from understanding how to support your vaginal microbiome.

So what is the vaginal microbiome? This refers to the intricate ecosystem of bacteria that live in the mucous layer within your vagina. In our digestive system it is important to have a wide array of bacteria present, however in the vagina it is healthy for Lactobacillus to be dominant.

When there is an increase in the diversity of bacteria in the vagina, it's an unhealthy state and referred to as bacterial vaginosis.

During your reproductive years, the vaginal microbiome is constantly changing due to fluctuations in reproductive hormones throughout a menstrual cycle. The fluctuations in hormones change the pH of the vagina and can be the reason why you might experience recurring vaginal symptoms at the same time of your cycle.

Before puberty, during pregnancy and in menopause, the vaginal microbiome is more stable. These life stages can be associated with their own vaginal conditions and women who aren't menstruating, due to PCOS or other condition, can also experience vaginal microbiome disruption due to the low levels of estrogen.

When your vaginal microbiome is healthy

When your vaginal microbiome is healthy, it's playing some important functions within your vagina:

  • protects against overgrowth by Candida

  • protects against sexually transmitted infections including HPV, HIV, Herpes, Chlamydia, gonorrhoea and trichomonas

  • reduces susceptibility to urinary tract infections

  • reduces your susceptibility to pelvic inflammatory disease, endometriosis and gynaecological cancers

  • a healthy microbiome is vital for fertility, prevention of miscarriage, and prevention of preterm birth.

Bacterial vaginosis (BV)

When your vaginal microbiome is out of balance it's known as bacterial vaginosis (BV). Symptoms of BV are watery, gushy vaginal discharge and a fishy odour. BV affects approximately 30% of women over their lifetime and for some women it can frequently reoccur.

It's good practice to always see your doctor for a swab to make sure you can identify the imbalance within your vagina before deciding on a course of treatment. Frequent mistreatment (such as anti-fungal creams) due to incorrect self diagnosis can worsen the microbial imbalances.

The standard medical treatment for bacterial vaginosis is oral antibiotic therapy, sometimes accompanied by an antibiotic vaginal cream. These methods can eradicate BV in some women, however many experience temporary remission followed by another flare within 3 months.

If you have recurrent BV, Candida, Herpes, HPV, infertility, or miscarriages, then a holistic assessment of your vaginal microbiome can be game changing. The aim is to identify the underlying cause(s) of your microbiome disruption and work with these factors to restore a healthy balance within your vagina.

Vaginal microbiome disruptors

What can cause disruption to your delicate microbiome?

  • being newly sexually active, having a new sexual partner, or multiple sexual partners, frequent sex

  • anything that you put into your vagina can affect the pH levels, including tampons, menstrual cups, sex toys, lubricants and condoms

  • vaginal cleanliness - either poor hygiene such as changing pads infrequently, or overuse of antimicrobial soaps, essential oils and douches

  • synthetic fabrics in underwear

  • smoking

  • changes in estrogen levels, such as fluctuations in the menstrual cycle; heavy or long periods; perimenopause; menopause; PCOS; absent periods; pregnancy

  • frequent antibiotics or anti-fungal treatments

  • diets high in sugar, or lacking in nutrients to support healthy reproductive hormones

  • stressful, busy lifestyle

Holistic assessment of your vaginal microbiome

A naturopathic treatment of vaginal dysbiosis involves uncovering and working with the factors that are most likely causing a disruption to your microbiome. This might mean modifying the way you have sex, or the hygiene practices that go with sex. It may involve changing your underwear, soap, lubricant, or some aspect of your diet.

If you are experiencing high levels of stress in your life, or imbalances in your menstrual cycle, then starting with these aspects of your health can achieve a breakthrough. I like to prescribe herbal remedies (both orally and intravaginally), targeted probiotics and nutritional changes.

The herbal medicines I prescribe for you may be directly affecting your microbiome (such as antimicrobial herbs), or they may be helping your health in other ways. Herbal formulas can assist with managing stress, reducing sugar cravings, balancing symptoms of high estrogen, or supporting women with low estrogen.

I also love to recommend flower essences to assist with the emotional aspects that often accompany vaginal health, sexual health and fertility.
