What are the Most Common Causes of a Red Diaper Rash?

A red diaper rash is commonly caused by chafing of the skin. This is a type of dermatitis that can make an infant's skin irritated, red, and blotchy. Urine and stool that comes into contact with a baby's dry skin can lead to what is commonly known as a red diaper rash. This rash is typically seen on the buttocks, and between folds of skin around the thigh area.

Moisture from a wet diaper often can lead to skin chafing and red diaper rash. Baby powder or petroleum jelly is often used to form a barrier against wetness, thus helping to prevent a rash. If left untreated, or if the diaper rash continues for an extended period of time, skin infections can develop that may require further treatment.

Other conditions can cause a red diaper rash as well. Eczema is a skin condition that can cause red scaly areas on various parts of the body. Typically, infants who develop eczema are older than six months of age. Although eczema is inherited from a parent, other factors can be involved. Skin allergies and sensitivity to detergents can also cause this problem.

Some infants who have been on a course of antibiotics may be prone to developing what is known as a yeast infection of the skin. This is a type of candida infection that typically results in red blotches along with an itchy and painful rash. In rare cases, a more severe red diaper rash from this type of dermatitis can result in fever as well.

Diaper rash ointments that contain zinc oxide can help to prevent irritations of the skin that can lead to a red diaper rash. There are specially developed products available that are meant to treat symptoms as well. Keeping the baby as dry as possible generally will prevent a red diaper rash from developing. It is also important to change diapers as needed.

Harsh detergents should always be avoided when washing baby clothes and cloth diapers. Pediatricians often recommend using a mild soap or detergent that is formulated especially for babies. If using disposable diapers, ones that are free of dyes or perfumes should be chosen. Certain types of baby wipes that are made with alcohol or similar ingredients may also irritate a baby's skin, causing a rash.

If the delicate skin of an infant becomes exposed to too much heat, a diaper rash can develop. Heat can contribute to the growth of bacteria and yeast. Toddlers who have begun the process of potty training often use plastic-type pants that fit over diapers and may trap heat longer. Therefore, it is recommended not to use two layers of material against the child's skin.

Because any type of rubbing against a baby's skin may cause a red diaper rash, it is also recommended to let a baby's skin "breathe" without a barrier of a diaper whenever possible. This can be done by placing a waterproof pad under the baby while allowing the skin to dry for a few hours daily. This will also prevent dampness and moisture from developing on baby's skin.
