One important factor is lacto bacteria. Under the influence of lacto bacteria, the glycogen released from the upper vaginal wall degrades to form the sugar glucose and then lactic acid. This results in an acid environment forming in the vagina, with a pH value that is usually 3.8 to 4.5. The physiological vaginal pH level is dependent on the quantitative presence of the lactic acid.

This acidic vaginal environment forms effective protection against infections because the vast majority of bacteria that cause disease cannot thrive under such conditions.

The pH level in vagina is subject to fluctuations. Possible causes of an alteration in the vaginal pH level are:

• bacterial vaginosis
• bacterial mixed infections
• sexually transmitted diseases
• premature rupture of fetal membranes
• estrogen deficiency
• postoperative infected wounds
• excessive intimate care

A physiological and therefore normal pH level (pH 3.8 to 4.5) is important for the body's system of protecting the vagina and the maintenance of a healthy vaginal flora. An increase in the vaginal level:

• decreases the quality of women's life who are affected by this
• constitutes a significant risk to health
• increases the risk of premature delivery

viola pH Health Care Test is the modern concept of protection for women

A disturbance in the micro ecological balance in the vagina (e.g. dysbiosis) is often connected with an increase in the pH level. Vaginal pH levels that are higher than 4.5 can lead to many gynaecological complaints and compilations.

Pregnant women can decrease the risk of infections by regularly self-assessing the vaginal pH level.
