Vaginitis refers to the inflammation of the vagina that can cause a range of symptoms such as itching, burning, and discharge. There are several synonyms for vaginitis that can be used interchangeably depending on the underlying cause and symptoms. Some common synonyms include yeast infection, bacterial vaginosis, trichomoniasis, vulvovaginitis, and candidiasis. Yeast infection is caused by an overgrowth of yeast in the vagina while bacterial vaginosis results from an imbalance of the vaginal bacteria. Trichomoniasis is caused by a parasitic infection, while vulvovaginitis refers to the inflammation of both the vulva and the vagina. Candidiasis is another type of yeast infection that may cause similar symptoms to vaginitis.
