What is vaginitis?
Vaginitis refers to any inflammation or infection of the vagina. It's common in women
of all ages. One-third of women have at least one form of vaginitis at some time
during their lives.
When the walls of the vagina become inflamed, because some irritant has disturbed
the balance of the vaginal area, vaginitis can occur.
What causes vaginitis?
Bacteria, yeast, viruses, chemicals in creams or sprays, and even clothing can cause
vaginitis. Sometimes, it occurs from organisms that are passed between sexual partners.
Also, a number of different factors can affect the health of your vagina. These include
your overall health, your personal hygiene, medicines, hormones (particularly estrogen),
and the health of your sexual partner. Changes in any of these factors can trigger
These are the most common types of vaginitis:
Your health care provider will consider other causes of vaginal discharge such as
gonorrhea and chlamydia. These organisms don't infect the vagina directly. If left
untreated, they can lead to serious conditions, such as pelvic inflammatory disease
(PID). PID increases a woman's risk of infertility, pelvic scarring, chronic pelvic
pain, and ectopic pregnancy. Chlamydia is one of the most common sexually transmitted
diseases in the U.S., although it often goes undiagnosed.
What is candida or "yeast" infections?
Yeast infections, as they are commonly called, are caused by one of the many species
of fungus known as candida. It normally lives in the vagina in small numbers. Candida
can also be present in the mouth and digestive tract in both men and women.
Yeast is normally present and well-balanced in the vagina. Infection occurs when something
upsets this normal balance. For example, taking an antibiotic to treat another infection
may upset this balance. In this case, the antibiotic kills the bacteria that normally
protects and balances the yeast in the vagina. In turn, the yeast overgrows, causing
an infection. Other factors that can cause imbalance include a weak immune system,
pregnancy, and diabetes.
What are the symptoms of a yeast infection?
The following are the most common symptoms of a candida infection:
A thick, white, cottage cheese-like vaginal discharge that is watery and usually odorless
Itching and redness of the vulva and vagina
Pain with urination or sex
The symptoms of a vaginal candida infection may look like other conditions or medical
problems. Always consult your health care provider for a diagnosis.
Who is at risk for yeast infections?
Any woman can get a yeast infection. A woman may be at an increased risk if she:
Has had a recent course of antibiotics
Has diabetes that is not well-controlled
Is taking an immunosuppressant medicine
Is using high-estrogen contraceptives
Is undergoing corticosteroid therapy, which weakens the immune system
How is a yeast infection diagnosed?
Your health care provider will review your medical history and do a physical and pelvic
exam. He or she may also examine the vaginal discharge with a microscope.
Treatment for yeast infection
Treatment for candida may include:
What is bacterial vaginosis?
Bacterial vaginosis is the most common type of vaginitis in women of reproductive
age. This infection is caused by bacteria, not yeast. With a bacterial vaginosis infection,
certain species of normal vaginal bacteria grow out of control and trigger inflammation.
What are the symptoms of bacterial vaginosis?
These are the most common symptoms for bacterial vaginosis:
A milky, thin discharge at times, or a heavy, gray or green discharge
"Fishy" odor (may become more noticeable during sex)
The symptoms of bacterial vaginosis may look like other conditions. Always consult
your health care provider for a diagnosis.
It is important to get prompt treatment for this condition if you are pregnant. Bacterial
vaginosis can cause complications during pregnancy and, in some cases, has been linked
to preterm delivery.
Treatment for bacterial vaginosis
Bacterial vaginosis is caused by bacteria; therefore, it is generally treated with
What is trichomoniasis?
Trichomoniasis, trichomonas, or "trich" as it is commonly called, is a sexually transmitted
infection. It is caused by a one-celled parasite called Trichomonas vaginalis that passes between partners during sex. Since most men do not get symptoms with trichomoniasis,
the infection is often not diagnosed until the woman develops symptoms of vaginitis.
What are the symptoms of trichomoniasis?
The following are the most common symptoms of trichomoniasis:
A frothy, often musty-smelling, greenish-yellow discharge
Itching or burning in and around the vagina and vulva
Swelling or redness at the opening of the vagina
Light bleeding, especially after sex
Burning during urination
Discomfort in the lower abdomen
Pain during sex
Some women with trichomoniasis have no symptoms. The symptoms of trichomoniasis may
look like other conditions or medical problems. Always consult your health care provider
for a diagnosis.
Treatment for trichomoniasis
Both partners must be treated for trichomoniasis to avoid reinfection. Treatment generally
involves taking oral antibiotics. If a woman has more than one sexual partner, each
partner (and any of their other partners) should also be treated.
It is especially important for pregnant women to get prompt treatment for trichomoniasis.
This type of vaginitis can cause complications during pregnancy and, in some cases,
has been linked to preterm delivery.
What is viral vaginitis?
Viruses are a common cause of vaginitis, with most being spread through sexual contact.
One type of virus that causes viral vaginitis is the herpes simplex virus (HSV, or
simply herpes). The main symptom is pain in the genital area associated with lesions
and sores. These sores are generally visible on the vulva, or vagina, but may be found
inside the vagina during a pelvic exam. Often stress or emotional situations can be
a factor in triggering an outbreak of herpes.
Another source of viral vaginitis is the human papillomavirus (HPV), a virus that
is also transmitted through sexual contact. HPV is the main cause of cervical cancer
in women. This virus also causes painful warts to grow on the vagina, rectum, vulva,
or groin. However, visible warts are not always present, in which case, the virus
is generally detected by a test for HPV done with a Pap test.
Two HPV vaccines are effective in preventing infection by the particular strains of
HPV that cause most cervical cancers, but they do not treat existing HPV infection
or genital warts. One of the vaccines also is effective against genital warts as well
as some cancers of the vulva, vagina, and anus. Both vaccines are approved for use
in females between the ages of 9 and 26. One of the two vaccines is available for
boys and men, ages 9 through 26, and protects against most genital warts. The vaccines
are given as a three-dose series.
What is noninfectious vaginitis?
Noninfectious vaginitis usually refers to vaginal irritation without an infection
being present. Most often, this is caused by an allergic reaction to, or irritation
from, vaginal sprays, douches, or spermicidal products. It may be also be caused by
sensitivity to perfumed soaps, detergents, or fabric softeners.
Another form of noninfectious vaginitis, called atrophic vaginitis, usually results from a decrease in hormones because of menopause, surgical removal
of the ovaries, radiation therapy, or even after childbirth--particularly in breastfeeding
women. Lack of estrogen dries and thins the vaginal tissue, and may also cause spotting.
What are the symptoms of noninfectious vaginitis?
The following are the most common symptoms of noninfectious vaginitis:
The symptoms of noninfectious vaginitis may look like other conditions or medical
problems. Always consult your health care provider for a diagnosis.
Treatment for noninfectious vaginitis
Treatment for noninfectious vaginitis depends greatly on the cause. If the cause is
a reaction to an irritant, the irritant should be avoided.
