Thrush is a fungal infection caused by an overgrowth of yeast-like organisms.

These organisms like warmth and moisture and are normal inhabitants of the skin, mouth, gut and vagina.

Thrush infections sometimes happen when your nipples become cracked or damaged. This means the candida fungus that causes thrush can get into your nipple or breast.

You may have a thrush infection in your breasts if:

  • you start to feel pain in both nipples and/or breasts after feeds, having previously having no pain after feeding. The pain may be quite severe and last for up to an hour after every feed.

It’s not likely to be thrush if:

  • you have experienced pain while feeding
  • the pain affects only one nipple or breast
  • you have a fever or there is a warm red patch on one of your breasts.
