Diaper Dermatitis

What is it?

Diaper dermatitis, better known as diaper rash, is a sore, red rash that appears on skin that is covered by a diaper.

Who gets it?

Diaper rash is the most common type of dermatitis in infants and children who wear diapers.

What causes it?

Diaper rashes are usually caused by prolonged contact with moisture. In addition, the bacteria found in bowel movements reacts with chemicals in urine and creates a build up of ammonia and other chemicals that irritate the skin. There is no apparent link between diaper rash and cloth or disposable diapers.

What are the symptoms?

The symptoms of diaper rash include a sore, red rash on the skin in the diaper area. The infant may cry when he or she urinates or has a bowel movement because it further irritates the skin. A rash that covers a large area, is bright red and raw, and is surrounded by red dots indicates a yeast infection.

How is it diagnosed?

Diaper rash is diagnosed by its appearance and location.

What is the treatment?

The best treatment for diaper rash is to keep the area as clean and dry as possible. This requires frequent diaper changes. Gently cleanse the skin after a bowel movement with a mild soap, rinse with warm water, then dry the skin completely. If the skin is cracked, you can apply a barrier cream to protect the skin from moisture. Your doctor will recommend that you let your child’s skin get as much air as possible. You can do this by letting your child nap without a diaper, placing a waterproof pad or open diaper under his or her bottom to protect the bed from urine or bowel movements while the child is sleeping. If you use cloth diapers, avoid plastic pants, which do not allow airflow. It’s a good idea to use disposable diapers at night because they pull the moisture away from the child’s skin. With treatment, diaper rashes should begin to heal within three days. Because a baby has a large ratio of skin to body weight, it is best to avoid steroid creams, which are absorbed into the bloodstream through the skin. Only use a steroid cream if recommended by your doctor for severe cases of diaper rash. A yeast infection is treated with a special antifungal cream.

Self-care tips

You can prevent diaper rash by changing diapers frequently so the skin stays dry. Applying a light layer of cornstarch may help to prevent diaper rash. Talcum powder should not be used because it can be inhaled and cause respiratory infections. If you wash your own cloth diapers, be sure to use bleach to sterilize the diapers. Contact your doctor if a diaper rash does not improve with treatment after several days.
