There is a good Candida Yeast & IBS thread in this forum. You can have an overgrowth and never hav a vaginal infection. Or you can have a vaginal infection and other problems that you don't even realize are the yeasties, or you can have an asymptomatic overgrowth. When you start LC you cut off the yeasties food supply and they start to die off. The toxins being released cause the symptoms you get, so actually it's not an overgrowth causing the vaginal infection at the start of LC WOL, it's the yeasties dying, which is a good thing. You need to start taking a probiotic to rebuild the good bacteria that you didn't know were missing and take an antifungal to finish off the bad guys. Here's a sit with very good info: http://candidapage.com Good luck!
