Which symptom is most commonly associated with a yeast infection?

Vulvar pruritus, or itching of the vulva, is the most commonly associated symptom of a yeast infection. This symptom occurs due to the irritation and inflammation caused by the overgrowth of Candida species, which is a type of yeast. The itching can be quite intense and is often one of the first signs that individuals notice, leading them to seek treatment.

While vaginal odor, increased vaginal discharge, and dysuria can also occur, they are not as characteristic of yeast infections. Vaginal odor is more commonly linked to bacterial vaginosis or other types of infections, while increased discharge in a yeast infection tends to be thick and white, resembling cottage cheese, and is not always present. Dysuria, or painful urination, is more commonly associated with urinary tract infections. Thus, vulvar pruritis stands out as the key symptom that typically indicates a yeast infection.
