Oral thrush is one such yeast infections that can cause discomfort. This condition comes in the form of a white rash inside one’s mouth and it’s caused by the candida fungus (yeast). Except for the inside of the mouth, it can also affect other parts of the body. For instance, in infants, it can cause diaper rash. In women, on the other hand, it can cause a vaginal yeast infection.
Although it is possible for anyone to get thrush, it is most often babies, toddlers, older adults, and people with weakened immune systems in general who suffer from it.
