Pregnancy, Microbiota, and the Importance of Gentle Intimate Care
During pregnancy, every detail of a woman’s health matters—not just for herself, but also for the growing baby. One area that often doesn’t get the attention it deserves in prenatal care is the balance of bacteria (microbiota) in the vulva and vagina. This delicate ecosystem plays a vital role in protecting both mother and child, and disruptions can actually have serious consequences...
Why the Vaginal Microbiota Matters
The vagina’s natural flora (good bacteria), acidic pH, and discharge together form a crucial barrier against infections. Beneficial bacteria, especially Lactobacillus, help keep the environment acidic, fight off harmful bacteria, and create substances that protect the vaginal ecosystem. This natural teamwork keeps the vagina healthy.
What Happens During Pregnancy
Pregnancy naturally brings changes to the vaginal microbiota. Levels of Lactobacillus typically increase, which is considered a positive adaptation. This bacteria helps maintain an acidic environment, preventing harmful bacteria from growing and creating a safer balance for both mother and baby.
At the same time, the vaginal microbiota often becomes more sensitive to disturbances during pregnancy. Good hygiene and early medical attention at the first sign of infection are therefore more important than ever.
Infections and Risks in Pregnancy
An untreated vaginal infection during pregnancy can lead to serious complications including miscarriage, preterm birth, or even fetal loss. Studies also show that even without infection, a higher vaginal pH increases the risk of premature birth.
One particular concern is Group B Streptococcus (GBS). If left untreated, GBS can lead to preterm delivery, neonatal meningitis, or postpartum infections. Maintaining a balanced vaginal microbiota provides natural protection against this bacteria.
Dr. Rebecka Kaplan, a specialist in gynecology and obstetics, explains that when a child is born vaginally, it is naturally exposed to the mother's microbiota, which provides the necessary bacteria to stimulate its immune system. Consequently, an imbalanced vaginal microflora can also affect the child's susceptibility to infections and increase the rist of developing allergies and asthma.
What Disrupts the Microbiota during Pregnancy?
Several factors can disturb this delicate balance:
-
Antibiotics: Reduce beneficial bacteria in both gut and vagina.
-
Stress: Psychological stress impacts gut health, which in turn influences the vaginal flora.
-
Sex: Introduces new bacteria and can cause micro-tears, which increase infection risk.
-
Hygiene: Over-washing or using the wrong products can disrupt pH and microbiota.
Supporting a Healthy Balance
Luckily, there are ways to help protect your microbiota during pregnancy:
-
Antibiotics: Use only when necessary. Support recovery with probiotics (Lactobacillus, Bifidobacterium), fermented foods like yogurt and kefir, and prebiotic-rich foods such as onions, garlic, bananas, and asparagus.
-
Stress: Incorporate stress-reducing practices into your daily routine—whether that’s gentle movement, meditation, or simply time to rest.
-
Sex: Practice good hygiene, use a natural lubricant to avoid micro-tears, and urinate after sex.
-
Hygiene: Wipe front to back, and cleanse the vulva daily—but no more than 1–2 times.
How to Cleanse the Vulva Safely During Pregnancy
Within the folds of the vulva, dirt and buildup can increase the infection risk. However, soaps (yes, even the mildest ones) can disrupt the pH and microbiota when used on this sensitive area. That’s why we recommend cleansing with natural oils.
Our Cleansing + Moisturising Oil Prebiotic + Postbiotic is the first intimate cleanser to receive the Kind to Biome® certification, meaning it’s scientifically proven not to disturb your natural bacterial balance.
