Women’s microbiota are highly sensitive and can be influenced by various factors and life events, including hormonal changes, antibiotic treatments, stress, and lifestyle choices. These conditions may disturb the delicate equilibrium of the vaginal microbiota, promoting the proliferation of harmful microorganisms and adversely affecting women’s daily quality of life.
Candidasis is one of the most prevalent causes of vaginal discomfort in women of reproductive age and is characterized by the disruption of the vaginal microbiota composition. About 90% of vaginal candidiasis infections are caused by Candida albicans overgrowth. Vaginal candidiasis is a widespread issue, with over 75% of women worldwide experiencing at least one episode in their lifetime.
