Vaginal yeast infection is caused by bacteria called Candida Albicans which is generally present in the vaginal area in comparatively small numbers. But sometimes the yeast multiplies and takes over quickly, flaring into a full blown yeast infection. There are several causes behind the yeast infection that are given here.
Antibiotics are a cause of yeast infection as they kill the “good” bacteria which unbalance the ecosystem of the vaginal area. Tight, dirty and non cotton clothes that do not allow the heat to escape can also cause this infection. Hormones, injury to the vaginal and surrounding areas and weak immune system can also cause the infection. It can also be transmitted sexually. Condoms and some chemicals like perfume, dye or ink can also cause the infection.
