What does it mean when you have thick white stuff in your vagina?

?yeast infection: Often, a thick white discharge can be indicative of a yeast infection, which can be a common vaginal infection. At times, there is no specific cause, just an overgrowth of the yeast causing an infection, other causes can be diabetes which causes yeast to thrive on a sugary vaginal environment, or recent antibiotic use which allow yeast overgrowth. You may want to see a gyn to be safe. Good luck.
