When we think about pregnancy, we often think about hormones, nutrition, supplements, and preparing for a baby.
But there is another powerful factor many women never hear about: the maternal microbiome.
Your microbiome is the community of beneficial bacteria that lives in the body — especially in the gut, vagina, skin, and mouth. During pregnancy, this ecosystem naturally changes and adapts to support both mother and baby.
And research now shows that its balance may play a bigger role than many people realize.
What happens to the microbiome during pregnancy?
Pregnancy creates major hormonal and immune changes. These shifts also affect the body’s bacteria.
The vaginal microbiome
During pregnancy, the vaginal microbiome often becomes more stable and more dominated by Lactobacillus — beneficial bacteria that help maintain an acidic pH and protect against unwanted microbes.
This is the body’s intelligent way of helping protect both mother and baby.
The gut microbiome
The gut microbiome also changes throughout pregnancy, especially in the third trimester, as the body adapts its metabolism and energy needs.
The oral microbiome
Even the bacteria in the mouth can shift during pregnancy, which is one reason oral health becomes especially important.
Why balance matters
A healthy microbiome is associated with positive pregnancy outcomes.
When the microbiome becomes imbalanced (sometimes called dysbiosis), studies have linked it to a higher risk of:
- preterm birth
- bacterial vaginosis (BV)
- urinary tract infections (UTIs)
- gestational diabetes
- preeclampsia
- low birth weight
- implantation challenges in fertility treatment
Especially important is the presence of protective Lactobacillus in the vaginal microbiome.
It may also influence your baby’s future health
The maternal microbiome does not only matter during pregnancy.
Research suggests it may also influence:
- immune system development
- metabolic health
- allergy risk
- asthma risk
- long-term wellbeing later in life
This is one reason the mother’s internal balance is so important.
Everyday choices can make a difference
While no one can control everything during pregnancy, supporting your natural balance can be a gentle and meaningful step.
Researchers often highlight the importance of:
- avoiding unnecessary antibiotics when possible
- supporting gut and vaginal health
- identifying infections early
- choosing microbiome-friendly products
- reducing unnecessary irritation in the intimate area
Why intimate care matters
The vulva is the outer gateway to the vaginal environment.
Harsh soaps, drying products, and unnecessary irritants may disturb the skin barrier and surrounding microbiome.
That is why gentle and microbiome-friendly intimate care becomes especially meaningful during pregnancy.
Our Cleansing + Moisturising Oil Prebiotic + Postbiotic is certified Kind to Biome, meaning it has been tested to show that it does not disrupt the natural vulvar microbiome.
In short
Your pregnancy microbiome is not a small detail. It is part of the foundation of both maternal and baby health.
By supporting your body’s natural balance, you are caring for more than just yourself — you are caring for the environment your baby begins in. 🤍
