Thrush is a yeast (fungal) infection that can affect the vagina, penis and skin.
Symptoms of thrush depend on where it is on the body. It usually causes itchiness, irritation and a white discharge that looks like cottage cheese.
Thrush can usually be treated with antifungal medicine from a doctor, pharmacist or sexual health clinic. Treatment should work within a week.
You’re more likely to get thrush if your skin is irritated or damaged, you're taking antibiotics or you have poorly controlled diabetes.
