Dysfunctional uterine bleeding is irregular vaginal bleeding. DUB may be caused by an imbalance of one of the hormones related to ovulation (estrogen or progesterone).

As many as 75 % of women experience genital candidiasis, also known as vulvovaginal candidiasis ( VVC ), candidal vaginitis, monilial vaginitis, monilial infection, and vaginal yeast infection during their lifetime. Overgrowth of the fungus Candida albicans, normally present in vaginal flora, causes an allergic reaction that produces symptoms. It most commonly occurs in sexually active young women and is the most commonly diagnosed vaginal infection.

Yeast infections are very common and they are reported by as many as 75% of women at some point in their lives. Vaginitis can be caused by a number of infections, including bacteria (such as Gardnerella and gonorrhea), protozoans (such as trichomonas), and yeast (Candida). Vaginal bacterial infections can be sexually transmitted, but can also be caused by douches and IUDS.
