What causes yeast infections to come back every 5 months?

Try a new diet: Some women are just prone to yeast infections. You need to wear cotton undies, not just cotton in the crotch. You need to shower after you work out. There is a diet in a book called the yeast connection which can be very helpful. It is perfectly safe to use over the counter anti yeast medication like Monistat whenever you get a yeast infection. The 7 night works best.
