What Are Causes and Risk Factors for a Yeast Infection Skin Rash?
An overgrowth of the fungus Candida is the cause of yeast infections. Candidal infections commonly occur in warm, moist body areas, such as the underarms or where skin folds over itself like breast/chest skin. Usually, the skin effectively blocks yeast, but any skin breakdown or cuts in the skin may allow this organism to penetrate and infect.
Areas typically affected by the fungus in babies include the mouth and diaper areas. Moist diapers can lead to an overgrowth of yeast.
In adults, oral yeast infections become more common with increased age. Adults can also have yeast infections around dentures, in the folds under the breast and lower abdomen, in the nail beds, and beneath other skin folds. Most of these candidal infections are superficial and clear up easily with treatment.
In women, vaginal yeast infections are the second most common reason for vaginal burning, itching, and discharge. Yeasts are found in the vagina of most women and can overgrow if the environment in the vagina changes. Antibiotic and steroid use is the most common reason for yeast overgrowth. However, pregnancy, menstruation, diabetes, and birth control pills can also contribute to developing a yeast infection. Yeast infections are more common after menopause.
Any person who has their immune system altered by disease (for example, HIV infection) or other reasons (for example, chemotherapy) is at higher risk to get a yeast infection. In some people, a yeast infection, especially if it is severe and/or recurrent, may be an indication that the person has a depressed immune system.
