ORAL THRUSH is a very common infection in infants that causes irritation in and around a baby’s mouth. It is caused by the overgrowth of the yeast (a type of fungus) called Candida albicans. Candida overgrowth can lead to vaginal (yeast) infections, diaper rashes, or oral thrush.
Most people (including infants) naturally have Candida in their mouths and digestive tracts, which is considered normal growth. The amount is controlled by a healthy immune system and some “good” bacteria. If the immune system is weakened (due to an illness or medicines like chemotherapy), or if the immune system is not fully developed as is the case in infants, the Candida in the digestive tract can overgrow and lead to an infection.
Sometimes Candida overgrowth occurs after a baby has received antibiotics for a bacterial infection, because antibiotics can kill off the “good” bacteria that keep the Candida from growing. Similarly, infection can occur with steroid use.
SymptomsOral thrush can affect anyone, although it’s most common in infants younger than 6 months and in older adults. A baby with oral thrush might develop cracked skin in the corners of the mouth or whitish patches on the lips, tongue, or inside the cheeks that look a little like cottage cheese but can’t be wiped away. Scraping the white patches off can cause some bleeding.
Many babies don’t feel anything at all, but some may be uncomfortable when sucking. Some babies may not feed well because their mouth feels sore.
Babies can have oral thrush and a diaper rash due to the same yeast at the same time.
PreventionAlthough oral thrush is a common infection in infancy, you can help prevent it:
- If you are formula-feeding your baby or using a pacifier, it’s important to thoroughly clean the nipples and pacifiers in hot water or dishwasher after each use. That way, if there’s yeast on the bottle nipple or pacifier, your baby doesn’t continue to get re-infected. Storing milk and prepared bottles in the refrigerator prevents yeast from growing.
- If you are breastfeeding and your nipples are red and sore, there’s a chance you may have a yeast infection on your nipples, and that you and the baby are passing it back and forth. If so, you may want to talk to the doctor about using an antifungal ointment on your nipples while the baby is being treated with the antifungal solution.
- Changing diapers frequently also prevents the fungal diaper rashes.
TreatmentSee your doctor if you think your baby may have thrush. Some cases go away without medical treatment within a week or two, but the doctor may prescribe an antifungal solution for your baby’s mouth. This medication is usually applied by painting it on the inside of the mouth and tongue with a sponge applicator.
And depending on your baby’s age, the doctor might suggest adding yogurt with lactobacilli to your child’s diet. The lactobacilli are the “good” bacteria that can help eliminate the yeast in your child’s mouth.
If your child keeps getting oral thrush, especially if he or she is older than 9 months, talk with your doctor because this might be an indication of another health issue. GFM
