A vaginal yeast infection, also called vulvovaginal candidiasis, occurs when Candida yeast grows excessively in the vagina and vulva. It is common and is not usually classified as a sexually transmitted infection.
Symptoms
Typical symptoms include intense itching or irritation around the vulva and vagina, soreness, redness, burning and a thick white vaginal discharge. Symptoms can resemble other vaginal infections, so a first episode, unusual symptoms or repeated infections should be medically assessed.
Treatment
Uncomplicated yeast infections are generally treated with antifungal medicines. The appropriate treatment depends on symptoms, pregnancy status, recurrence and other health factors. Antibiotics do not treat Candida infections.
When to seek medical advice
Seek medical advice if this is your first suspected yeast infection, symptoms are severe or keep returning, treatment does not work, you are pregnant, or you have diabetes or a weakened immune system. Fever, pelvic pain, foul-smelling discharge or abnormal bleeding may indicate another condition and should be assessed.
