Vaginal Yeast Infections

What Happens

Vaginal yeast infections often clear up on their own without treatment, usually when menstruation begins. Menstrual blood raises the vaginal pH, causing the number of yeast cells to decrease because they can't grow in the pH present during menstruation.

There are significant differences between occasional, easily treatable yeast infections and recurrent infections that seriously affect a woman's life. Recurring vaginal yeast infections can be difficult to prevent or cure. Women who have recurring yeast infections should be evaluated for underlying causes (such as treatment- resistant strains of yeast, diabetes, or hormone therapy) so that the cause can be treated or reversed.
