Unpleasant odour, urinary tract involvement or blood not associated with menstruation, requires referral to the doctor. Males, usually asymptomatic, can carry the yeast on their penis. One of the most common complications in the use of broad spectrum antibiotics in females is an overgrowth of Candida. Pregnancy may cause the condition and some experts believe that oral contraceptives are also implicated. Both result in hormonal changes which may alter the vaginal environment and promote the proliferation of the fungus.

This may be a result of the elevated glucose blood level. Other predisposing factors include wearing tight clothing in the groin area and taking immunosuppressives. Rarely, personal deodorants and bath additives can cause vaginal thrush. Not using these may result in natural regression of the condition. The condition is not cyclical and can occur during any part of the menstrual cycle.
