What factors are Responsible for Imbalance pH Level of Vagina?


Keeping the pH balance of the vagina is necessary to maintain it healthy. A pH less than 7 is acidic, while a pH higher than 7 is basic. A normal vaginal pH is generally less than 4.5. The lower the pH, the more acidic the vaginal environment will be. A high pH in the vagina may cause infections as it can allow bacteria and yeast to increase.

A normal range of vaginal pH is between 3.8 and 4.5. This pH range can help to keep bacterial and fungal infections away. Lactobacilli bacteria present in the vagina secrete lactic acid and hydrogen peroxide that gives the vagina its acidic pH level.

Vaginal pH may change throughout a woman’s life. It is generally more than 4.5 before a woman has her first menstrual period and after menopause. But it is generally less than 4.5 during a woman’s reproductive years unless a condition or infection increases it.


Causes of changes in vaginal pH include the following:

  • Bacterial vaginosis
  • Douching
  • Menopause
  • Other vaginal infections
  • Presence of menstrual blood
  • Presence of semen
  • Taking antibiotics
  • Urinary tract infections (UTIs)
  • Other conditions like infertility, premature birth etc.

We should have a clear idea of the normal range of pH level. To diagnose the pH level, we should consult the gynecologist in Gurgaon to keep our Vagina Healthy.
