Visible vaginal yeast infection symptoms include a red, swollen vulva and thick, white vaginal discharge that resembles cottage cheese, according to Mayo Clinic. Many patients also experience vaginal itching and irritation, painful sexual intercourse and a burning sensation in the vagina.
An overgrowth of the candida fungus causes vaginal yeast infections, explains Mayo Clinic. Common causes of overgrowth include pregnancy, antibiotic use, uncontrolled diabetes or an impaired immune system. Mild to moderate yeast infections can normally be treated with over-the-counter vaginal therapies. Some doctors choose to prescribe Diflucan, an oral antifungal medication.
Patients can reduce their risk of obtaining yeast infections by avoiding douching, wearing cotton underwear, avoiding tight-fitting pants and underwear, and changing out of wet clothes as soon as possible, advises Mayo Clinic.
