Vaginitis

Alternative names

Vulvovaginitis; Vaginal inflammation; Inflammation of the vagina

Definition

Vulvovaginitis is characterized by inflammation (swelling, redness, and irritation caused by the presence of extra immune cells) or infection of the vulva and vagina.

Causes, incidence, and risk factors

Vulvovaginitis can affect women of all ages and is extremely common. It can be caused by bacteria, yeasts, viruses, and other parasites. Some sexually transmitted diseases can also cause vulvovaginitis, as can various chemicals found in bubble baths, soaps, and perfumes. Environmental factors such as poor hygiene and allergens may also cause this condition.

Candida albicans, which causes yeast infections, is one of the most common causes of vulvovaginitis in women of all ages. Antibiotic use can lead to yeast infections by killing the normal antifungal bacteria that live in the vagina. Yeast infections typically cause genital itching and a thick, white vaginal discharge.

Another cause of vulvovaginitis is bacterial vaginosis, an overgrowth of certain types of bacteria in the vagina. Bacterial vaginosis may cause a thin, grey vaginal discharge and a fishy odor.

A sexually transmitted disease called Trichomonas vaginalis infection is another common cause. This infection leads to genital itching, a vaginal odor, and a heavy vaginal discharge, which may be yellow-grey or green in color.

Bubble baths, soaps, vaginal contraceptives, feminine sprays, and perfumes can cause irritating itchy rashes in the genital area, while tight fitting or nonabsorbent clothing sometimes cause heat rashes.

Irritated tissue is more susceptible to infection than normal tissue, and many infection-causing organisms thrive in environments that are warm, damp, and dark. Not only can these factors contribute to the cause of vulvovaginitis, they frequently prolong the recovery period.

A lack of estrogen in postmenopausal women can result in vaginal dryness and thinning of vaginal and vulvar skin, which may also lead to or worsen genital itching and burning.

Nonspecific vulvovaginitis (where no causative organism or irritant can be identified) can be seen in all age groups, but it occurs most commonly in young girls before puberty. Once puberty begins, the vagina becomes more acidic, which tends to help prevent infections.

Nonspecific vulvovaginitis can occur in girls with poor genital hygiene and is characterized by a foul-smelling, brownish-green discharge and irritation of the labia and vaginal opening. This condition is often associated with an overgrowth of a type of bacteria that is typically found in the stool. These bacteria are sometimes spread from the rectum to the vaginal area by wiping from back to front after using the bathroom.
