Thrush (candidiasis)

Find out about the symptoms, causes and treatment of thrush.

Thrush is a yeast infection that is caused by a fungus that lives naturally in the body. It’s not a sexually transmitted infection (STI), but it can be passed on during sex.

Signs and symptoms of thrush

Anyone can both get thrush but it’s much more common in people with a vagina. It’s estimated that three out of four women will develop it at some point in their lives.

Symptoms of thrush for people with a vagina can include:

  • Vaginal discharge that has no smell but is either thick and white (a bit like cottage cheese) or thin and watery
  • Itching and soreness around the vagina entrance
  • In more serious cases, you may experience swelling of the vagina and cracked skin around the entrance
  • Stinging when you wee

Symptoms of thrush for people with a penis can include:

  • A cottage cheese-like discharge under the foreskin of the penis that may smell
  • The penis may become sore, itchy and inflamed
  • Stinging when you wee
