Overview

Diaper dermatitis is inflammation of the skin in the diaper area. It’s a very common condition in babies and toddlers.

Causes

In most cases, diaper dermatitis is a type of contact dermatitis. That means the skin is inflamed from contact with certain substances. In diaper dermatitis, urine and feces irritate the skin. 

Other common causes of diaper dermatitis include:

  • Candida. This is a yeast infection in the diaper area. Candida infection may occur if contact dermatitis is not treated within a few days.
  • Seborrhea. This is a common, long-term skin condition. The cause of seborrhea is not known. It usually affects the diaper area and other parts of the body.

Other less common causes of dermatitis in the diaper area include:

  • Bacteria. Staph or strep bacteria can cause it.
  • Allergies. It can be caused by an allergic reaction to dye in disposable diapers, or detergent used to wash cloth diapers.

Risk Factors

Any baby or toddler can develop diaper dermatitis. Things that increase the risk include:

  • You don't change your child's diapers often enough
  • Your child has diarrhea or frequent bowel movements
  • Your child is taking antibiotic medicines. Or you are taking antibiotics and you are breastfeeding.

Symptoms

The symptoms of diaper dermatitis vary depending on the cause. And symptoms can occur a bit differently in each child. They can include:

  • Contact diaper dermatitis. Skin that is irritated from urine and feces will look red and shiny. The skin on the buttocks, thighs, belly (abdomen), and waist may be affected. The skin creases or folds are usually not affected.
  • Candida diaper dermatitis. The skin is a deep red color with patches outside of the diaper area. A baby may also have a yeast infection in the mouth (thrush). The creases or folds of the thighs and in the diaper area are usually affected. 
  • Seborrheic diaper dermatitis. The skin is red with yellow, oily patches. It also affects the skin folds. It also usually affects the face, scalp, or neck at the same time.

The symptoms of diaper dermatitis can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

Diagnosis

The healthcare provider will ask about your child’s symptoms and health history. He or she will give your child a physical exam. Your child's healthcare provider may advise lab tests, but they are usually not needed.

Treatment

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on the cause, and how severe the condition is. Treatment may include:

  • Periods of time without wearing diapers
  • Frequent diaper changes
  • Ointment put on the diaper area to protect the skin
  • Antifungal cream or ointment for a Candida infection
  • Corticosteroid cream for more severe dermatitis
  • Antibiotic medicine for a bacterial infection
