Many factors can disturb the natural balance in the vagina, and if they become too intense, the vaginal flora can no longer adapt, which may result in a vaginal infection. The number of lactobacilli in the vagina is usually then reduced and the pH is also often raised to values above 4.4.

Vaginal complaints such as itching, burning and discharge, can be signs of a bacterial or yeast infection and thus of an imbalance in the vaginal flora. These symptoms must be seen.
With lactic acid products, women who are susceptible to recurrent vaginal infections can restore and maintain a healthy vaginal environment and thus help prevent vaginal infections (see Vagisan Lactic Acid).
