Vaginal Infections (Vaginitis)

Vaginal Infections Overview

Vaginal infections, or vaginitis is an inflammation of the vagina that creates discharge, odor, irritation, or itching. It is difficult to diagnose because vaginitis has many causes. Women use a variety of over-the-counter medications to treat the itching, discharge, and discomfort of these conditions.

  • The vagina creates its own environment and maintains a balance among the normal bacteria found there and the hormonal changes in a woman's body. Vaginitis occurs when the vaginal ecosystem has been changed by certain medications such as antibiotics, hormones, contraceptive preparations (oral and topical), douches, vaginal medication, sexual intercourse, sexually transmitted diseases, stress, and change in sexual partners.
  • Some vaginal infections are transmitted through sexual contact, but others such as yeast infections probably are not. Vaginitis means inflammation and is often caused by infections, but may be due to hormonal changes (especially when a woman is going through menopause) or due to trauma in young girls. Some infections are associated with more serious diseases.

  • Three vaginal infections are the most common. Their causes are quite different but, their signs and  symptoms are similar, and treatments of the three conditions vary.
  1. Bacterial vaginosis

  2. Vaginal yeast infection

  3. Trichomoniasis
  • Many women often mistakenly think they have a "yeast infection" and treat themselves when, in fact, they have a similar vaginal infection that will not respond to self-treatment with over-the-counter yeast medications. A study by the American Social Health Association found that 70% of women self-treated vaginal infections before calling a health care provider. Most often, they incorrectly thought they had a yeast infection when, in fact, it was bacterial vaginosis.
  • The important thing is not to guess, but to recognize the symptoms if you develop a vaginal infection. If you have any concerns, see your health care practitioner for precise testing and to get the most appropriate and effective treatment right away.
