Vulvovaginitis is inflammation or infection of the vulva and vagina.
Vaginitis; Vaginal inflammation; Inflammation of the 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 infections (STIs) 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, and other symptoms. For more information see:
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.
An STI called
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.
Some skin conditions can cause itching and chronic irritation of the vulvar area. Foreign bodies, such as lost tampons, can also cause vulvar irritation and itching and strong smelling discharge.
Nonspecific vulvovaginitis (where specific cause cannot be identified) can be seen in all age groups, but it occurs most commonly in young girls before puberty. Once puberty begins, the
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.
Sexual abuse should be considered in girls with unusual infections and recurrent episodes of unexplained vulvovaginitis. Neisseria gonorrhoeae, the organism that causes
- Irritation and itching of the genital area
- Inflammation (irritation, redness, and swelling) of the labia majora, labia minora, or perineal area
- Foul vaginal odor
- Discomfort or burning when urinating
Signs and tests
If you have been diagnosed with a yeast infection in the past, you can try treatment with over-the-counter products. However, if your symptoms do not completely disappear in about a week, contact your health care provider. Many other infections have similar symptoms.
The health care provider will perform a pelvic examination. This may show red, tender areas on the vulva or vagina.
A biopsy of the irritated area on the vulva may be recommended if there are no signs of infection.
Treatment depends on what is causing the infection. Treatment may include:
- Antibiotics taken by mouth or applied to the skin
- Antifungal cream
- Antibacterial cream
- Cortisone cream
- Antihistamine, if the irritation is due to an allergic reaction
- Estrogen cream, if the irritation and inflammation is due to low levels of estrogen
Proper cleansing is important and may help prevent irritation, particularly in those with infections caused by bacteria normally found in stool. Sitz baths may be recommended.
It is often helpful to allow more air to reach the genital area. Here are some tips:
- Wear cotton underwear (rather than nylon) or underwear that has a cotton lining in the crotch area. This increases air flow and decreases moisture.
- Do not wear pantyhose.
- Wear loose-fitting clothing.
- Remove underwear at bedtime.
Note: If a sexually transmitted infection is diagnosed, it is very important that any other sexual partners receive treatment, even if they do not have symptoms. If your sexual partner is infected but not treated, you risk becoming infected over and over again.
Proper treatment of an infection is usually very effective.
- Discomfort that does not go away
- Skin infection (from scratching)
- Increased risk of getting HIV if you come into contact with the virus when you have a vaginal infection or irritation
Calling your health care provider
Call your health care provider if vulvovaginitis symptoms are present or if known vulvovaginitis does not respond to treatment.
Use of a condom during sexual intercourse can prevent most sexually transmitted vaginal infections. Proper fitting and adequately absorbent clothing, combined with good hygiene of the genital area, also prevents many cases of noninfectious vulvovaginitis.
Children should be taught how to properly clean the genital area while bathing or showering. Proper wiping after using the toilet will also help (girls should always wipe from the front to the back to avoid introducing bacteria from the rectum to the vaginal area).
Hands should be washed thoroughly before and after using the bathroom.
