The fungus candida causes a vaginal yeast infection. Your vagina naturally contains a balanced mix of yeast, including candida, and bacteria. Lactobacillus bacteria produce acid, which prevents yeast overgrowth. That balance can be disrupted and lead to a yeast infection. Too much yeast in your vagina causes vaginal itching, burning and other classic signs and symptoms of a yeast infection. Candida albicans is the most common type of fungus to cause yeast infections. Sometimes, other types of candida fungus are to blame. Common treatments usually cure a Candida albicans infection. Yeast infections caused by other types of candida fungus can be more difficult to treat, and need more aggressive therapies.
