What is thrush?
Thrush is a yeast infection that causes white patches in the mouth and on the tongue. Thrush is most common in babies and older adults, but it can occur at any age. Thrush in babies is usually not serious.
What causes thrush?
You get thrush when a yeast called Candida, normally found on the body, grows out of control.
In babies, Candida causes thrush because babies' Reference immune systems Opens New Window are not yet strong enough to control the growth of the yeast. Older people get thrush because their immune systems can weaken with age.
Some people get thrush when they take certain medicines, such as Reference antibiotics Opens New Window or Reference inhaled corticosteroids Opens New Window. People who have certain health problems, such as diabetes or HIV, are also more likely to get thrush.
What are the symptoms?
In babies, it is easy to mistake thrush for milk or formula. It looks like cottage cheese or milk curds. Don't try to wipe away these patches, because you can make them red and sore. Some babies with thrush can be cranky and do not want to eat.
Talk to your doctor if you think you or your child has thrush.
How is thrush diagnosed?
In most cases, doctors can diagnose thrush just by looking at the white patches. Your doctor will also ask you questions about your health. If your doctor thinks that another health problem, such as diabetes, may be related to your thrush, you may also be tested for that condition.
How is it treated?
Thrush is usually treated with prescribed antifungal medicine such as nystatin liquid. In most cases, you will put the medicine directly on the white patches. When a baby has thrush, the yeast can cause a diaper rash at the same time as thrush. Your doctor may prescribe nystatin cream or ointment for his or her diaper area.
To treat thrush in adults, at first you will probably use medicine that goes directly on the white patches, such as a liquid or a lozenge. If these medicines don't work, your doctor may prescribe an antifungal pill.
How can you manage thrush?
If your baby has thrush, it may help to:
- Clean bottle nipples and pacifiers regularly using hot water.
- Dry your nipples and apply lanolin lotion after breast-feeding. Your doctor may also prescribe a medicine that you can put on your nipples. Breast-feeding mothers and babies can pass a yeast infection back and forth.
If you wear dentures and have thrush, be sure to clean your mouth and dentures every night. You can soak them overnight in a denture cleaner that you buy at the store. Rinse your dentures well after soaking them.
