Vaginal pH is a measure of how acidic or basic your vaginal environment is. A healthy vaginal pH is mildly acidic and ranges between a pH of 3.8 - 5.0. The pH level of your vagina plays an important part in keeping your vagina healthy. A healthy vagina is home to different types of acid-producing bacteria (Lactobacillus) which provide natural protection against infections. The acidic environment creates a barrier that prevents unhealthy bacteria (Bacterial Vaginosis) yeast (Candidiasis) and trich (Trichomoniasis) from multiplying too quickly.
An imbalance in the vaginal ecosystem can alter the vaginal pH and tip the scale to the point of causing infection, itching, burning, inflammation, unusual odor, discharge and pain during sex. Vaginal infections also increase the risk of acquiring sexually transmitted diseases (STDs) and are associated with adverse reproductive health outcomes.
In a woman’s daily life many factors lead to changes or imbalances in the vaginal pH, including – interactions with intimate partners, unprotected sex (semen), antidepressants, along with estrogen changes during menstrual cycles, use of hormonal contraceptives, during breastfeeding and menopause. Antibiotics can also wipe out healthy vaginal microbiome.
