Yeast Infection Skin Rash Causes
Candidal infections commonly occur in warm moist body areas, such as underarms. Usually, the skin effectively blocks yeast, but any breakdown or cuts in the skin may allow this organism to penetrate.
Typical affected areas in babies include the mouth and diaper areas.
In adults, oral yeast infections become more common with " increased age. " ... Adults can also have yeast infections around dentures, under the breast and lower abdomen, in the nailbeds, 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, sperm, diabetes, and birth control pills can also contribute to developing a yeast infection. Yeast infections are more common after menopause.
