Who is likely to have an alkaline vaginal pH?

Menopausal women are likely to have an alkaline vaginal pH due to hormonal changes that reduce estrogen levels. Estrogen plays a critical role in maintaining the acidic environment of the vagina by promoting the growth of lactobacilli, the bacteria that produce lactic acid. As estrogen decreases during menopause, lactobacilli also decrease, leading to less production of lactic acid and an increase in vaginal pH towards a more alkaline state.

This change in pH is significant, as a more alkaline environment can affect the vaginal flora and may increase the risk of infections. Understanding the effects of hormonal changes on vaginal health is crucial for managing symptoms and promoting well-being in menopausal women.

In contrast, the vaginal pH in pregnant women, adolescent females, and infants tends to be more acidic due to different physiological factors and the presence of certain hormones or microbiota that promote a lower pH environment.
