Vaginitis signs and symptoms may include:
- Change in color, odor or amount of discharge from your vagina
- Vaginal itching or irritation
- Pain during intercourse
- Painful urination
- Light vaginal bleeding or spotting
The characteristics of vaginal discharge may indicate the type of vaginitis you have. Examples include:
- Bacterial vaginosis. You may develop a grayish-white, foul-smelling discharge. The odor, often described as fish-like, may be more obvious after sexual intercourse.
- Yeast infection. The main symptom is itching, but you may have a white, thick discharge that resembles cottage cheese.
- Trichomoniasis. An infection called trichomoniasis (trik-o-moe-NIE-uh-sis) can cause a greenish yellow, sometimes frothy discharge.
When to see a doctor
See your doctor if you develop any unusual vaginal discomfort, especially if:
- You've never had a vaginal infection. Seeing your doctor can establish the cause and help you learn to identify the signs and symptoms.
- You've had vaginal infections before, but in this case, it seems different.
- You've had multiple sex partners or a recent new partner. You could have a sexually transmitted infection. The signs and symptoms of some sexually transmitted infections are similar to those of a yeast infection or bacterial vaginosis.
- You've completed a course of over-the-counter anti-yeast medication and your symptoms persist, you have a fever, or you have a particularly unpleasant vaginal odor. These are signs the infection may be from something other than yeast or from a resistant strain of yeast.
You probably don't need to see your doctor every time you have vaginal irritation and discharge, particularly if:
- You've previously had a diagnosis of vaginal yeast infections and your signs and symptoms are the same as before
- You know the signs and symptoms of a yeast infection and you're confident that you have a yeast infection
The cause depends on the type of vaginitis you have.
Bacterial vaginosis results from an overgrowth of one of several organisms normally present in your vagina. Usually, "good" bacteria (lactobacilli) outnumber "bad" bacteria (anaerobes) in your vagina. But if anaerobic bacteria become too numerous, they upset the balance, causing bacterial vaginosis. This type of vaginitis seems to be linked to sexual intercourse — especially if you have multiple sex partners or a new sex partner — but it also occurs in women who aren't sexually active.
A yeast infection occurs when there's an overgrowth of a fungal organism — usually C. albicans — in your vagina. Besides causing most vaginal yeast infections, C. albicans also causes infections in other moist areas of your body, such as in your mouth (thrush), skin folds and nail beds. The fungus can also cause diaper rash.
Trichomoniasis is a common sexually transmitted infection caused by a microscopic, one-celled parasite called Trichomonas vaginalis. This organism spreads during sexual intercourse with someone who already has the infection. In men, the organism usually infects the urinary tract, but often it causes no symptoms. In women, trichomoniasis typically infects the vagina, and usually it causes symptoms.
Vaginal sprays, douches, perfumed soaps, scented detergents and spermicidal products may cause an allergic reaction or irritate vulvar and vaginal tissues. Thinning of the vaginal lining — a result of decreased hormone levels following menopause or surgical removal of your ovaries — can also cause vaginal itching and burning.
Factors that increase your risk of developing vaginitis include:
- Hormonal changes, such as those associated with pregnancy, birth control pills or menopause
- Sexual activity
- Having a sexually transmitted infection
- Medications, such as antibiotics and steroids
- Uncontrolled diabetes
- Use of hygiene products such as bubble bath, vaginal spray or vaginal deodorant
- Wearing damp or tight-fitting clothing
- Using an intrauterine device (IUD) for birth control
Generally, vaginal infections don't cause serious complications. In pregnant women, however, symptomatic bacterial vaginosis and trichomoniasis have been associated with premature deliveries and low birth weight babies. Women with trichomoniasis or bacterial vaginosis are also at a greater risk of acquiring HIV and other sexually transmitted infections.
Good hygiene may prevent some types of vaginitis from recurring and may relieve some symptoms:
- Avoid baths, hot tubs and whirlpool spas. Rinse soap from your outer genital area after a shower, and dry the area well to prevent irritation. Don't use scented or harsh soaps, such as those with deodorant or antibacterial action.
- Avoid irritants. These include scented tampons and pads.
- Wipe from front to back after using the toilet. Doing so avoids spreading fecal bacteria to your vagina.
Other things that may help prevent vaginitis include:
- Don't douche. Your vagina doesn't require cleansing other than normal bathing. Repetitive douching disrupts the normal organisms that reside in the vagina and can actually increase your risk of vaginal infection. Douching won't clear up a vaginal infection.
- Use a latex condom. Both male and female latex condoms may help you avoid infections spread by sexual contact.
- Wear cotton underwear. Also wear pantyhose with a cotton crotch. If you feel comfortable without it, skip wearing underwear to bed. Yeast thrives in moist environments.
