It’s more common than you think. Thrush is a vaginal yeast infection caused by excessive growth of natural yeast-like fungus, called candida albicans.
If you’ve noticed vaginal irritation and inflammation, you may have a yeast infection. This occurs when the good bacteria in your vagina cannot keep the fungus under control, or when your immune system is weakened. Just so you know, thrush is not a sexually transmitted infection.
