What causes a vaginal yeast infection?

Fungus candida Albicans is the root cause of a majority of vaginal yeast infections.  

The vagina houses a mix of yeast and bacteria. Usually, there is a natural balance between them, and certain bacteria act to prevent the overgrowth of yeast.

When the balance is disrupted, there can be an overgrowth of particular funguses nestled more profound in the vaginal cell layers. These overgrown fungi will cause the symptoms of yeast infection.

Overgrowth of the yeast can be a result of pregnancy, Diabetes, weak immune system, medications and hormone therapy or oral contraceptives.
