What are causes of yeast infection

Hello. Thank you for posting.

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.

Overgrowth of yeast can result from:
Antibiotic use, which decreases lactobacillus bacteria in your vagina and changes the pH of your vagina.
Pregnancy.
Uncontrolled diabetes.
Impaired immune system
Taking oral contraceptives or hormone therapy, which increases estrogen levels.

Candida albicans is the most common type of fungus to cause yeast infections.
