What is a vaginal yeast infection?
Vaginal yeast infections are caused by a fungus called Candida albicans. Yeast are tiny organisms that normally live in small numbers on the skin and inside the vagina. The acidic environment of the vagina helps keep yeast from growing. If the vagina becomes less acidic, too many yeast can grow and cause a vaginal infection.
Are yeast infections common?
Yeast infections are so common that every 3 out of 4 of women will have one in their lifetime. Half of all women have more than one infection in their lifetime.
