Vaginal thrush is a common fungal infection. Recurrent infections occur in about 10% of women. It is important to complete the course of treatment (often clotrimazole (Canesten) pessaries) to eradicate the fungus. A partner who shows symptoms should also be diagnosed and treated. With recurrent thrush, test for diabetes. Simple self-help measures may be helpful, as may attention to personal hygiene. Postmenopausal women are often susceptible because of reduced vaginal lubrication. A vaginal jelly can be helpful.
