One of the most common reasons for patients to present to a gynecologist is the evaluation of vaginal discharge and discomfort related to vaginitis, sometimes caused by a yeast infection or bacterial vaginosis. The diagnosis of vaginitis involves taking samples from the vagina to see if an infection is present. If an infection is found, oral or vaginal treatments may be prescribed. Pregnant patients may require different treatment for vaginitis than non-pregnant patients. It is recommended to avoid placing anything in the vagina, including over the counter treatments, for 24 hours prior to evaluation of vaginitis in the office.
