Recurrence of bacterial vaginosis is very common.
Eating certain types of yogurt or other foods containing lactobacilli can boost the number of good bacteria in your vagina and re-establish a balanced vaginal environment.
Use mild, nondeodorant soaps and unscented tampons or pads. Keep the area dry to prevent irritation.
The practice of rinsing out your vagina with water or douching upsets the natural balance of your vaginal environment. If your natural vaginal environment doesn't produce enough of the good lactobacilli bacteria, you're more likely to develop bacterial vaginosis.
