Vaginitis is often caused by infections. Some vaginal infections are passed through sexual contact. Some infections occur if there is a change in the balance of organisms normally found in the vagina.1
In about 90% of affected women, vaginitis is caused by one of these types of infection2:
Vaginitis has other causes, too. For instance, some women are sensitive or allergic to vaginal sprays, douches, spermicides, soaps, detergents, and fabric softeners. These products can cause burning, itching, and discharge, even if there is no infection. Women also can have vaginal irritation caused by the natural lessening in estrogen levels during breast-feeding and after menopause.
A woman may have more than one cause of vaginitis at the same time.1
