That’s when bad bacteria easily start to overgrow and cause problems.
How does that happen? How do you get to the point where your vaginal pH is out of balance? There are several ways a vaginal pH imbalance happens. Let’s take a look at a few.
1- In a cruel twist of fate, the pH of semen is actually between 7.2 and 7.8. Yes, that means having unprotected sex can change your vaginal pH level — although it’s usually temporary. (3)
2- Douching can significantly disrupt vaginal pH balance. Douching is tied to all sorts of negative health outcomes for women, especially vaginal infections and sexually transmitted infections.(4,5,6)
And yet, due to outdated societal norms, many are still doing it. Don’t buy into the narrative that you need to “clean” your vagina. It is a self-cleaning organ, and douching does way more harm than good.
3- Antibiotic use can also make your vaginal pH imbalanced. This is because antibiotics can destroy your vaginal microbiome and kill off the plentiful “good” bacteria like Lactobacillus that help create a balanced environment in your vagina, vulva, and urethra. (7,8)
4- Your estrogen levels affect your vaginal pH in a big way. When your estrogen levels start to wane due to perimenopause and menopause — your vaginal pH is significantly impacted. Without sufficient estrogen, your vaginal pH becomes more basic. Remember, you ideally want your vaginal pH to be slightly acidic. (9,10)
