Diaper Rash: Causes, Symptoms, Treatment, and Prevention

Diaper rash is a common skin condition that affects babies and adults who wear diapers. More than half of all babies experience diaper rash, especially between the ages of 4 and 15 months. This article will help you understand the causes, symptoms, treatment options, and prevention methods for diaper rash.

What Causes Diaper Rash?

Diaper rash can occur due to various reasons, including:

  • Prolonged exposure to wet or dirty diapers

  • Skin chafing against the diaper

  • Yeast or bacterial infections

  • Allergic reactions to diapers, soaps, detergents, or baby wipes

Babies are more likely to develop diaper rash when they are older (between 9 and 12 months), sleep in soiled diapers, have diarrhea, start eating solid foods, or are taking antibiotics.

Symptoms of Diaper Rash

Common symptoms of diaper rash include:

  • Red, irritated skin in the buttocks or genital areas

  • Lighter skin in affected areas (for babies with darker skin tones)

  • Itchy skin or sores in the diaper area

  • Increased fussing and crying during diaper changes

If the rash is bleeding, has crusty sores, blisters, or oozes pus, contact your pediatrician.

Types of Diaper Rash

There are several types of diaper rash, including:

  • Yeast diaper rash: Caused by fungal overgrowth, appearing as red or pink patches with sharp edges or tiny pimples in skin folds

  • Irritant dermatitis: The most common type, caused by urine and feces irritating the skin

  • Bacterial diaper rash (impetigo): Caused by bacteria such as staph and strep, appearing as bright red skin or crusty, oozing pimples

  • Allergic diaper rash: Rare, caused by an allergic reaction to substances in soaps, detergents, wipes, or diapers

Treating Diaper Rash

The best way to treat diaper rash is to keep your baby's bottom clean and dry. When changing diapers:

  1. Rinse the diaper area with warm water and pat dry

  2. Use soap only if necessary

  3. Allow the skin to air-dry or use a towel

  4. Apply a diaper cream or ointment containing zinc oxide

  5. Rediaper your baby

If home care doesn't work, your pediatrician may recommend antifungal creams, antibiotics, or mild steroid creams.

Home Remedies for Diaper Rash

Some home remedies, such as applying breast milk or using coconut oil, may help soothe diaper rash. However, it's best to consult your pediatrician before trying any home remedies, as some (like cornstarch or undiluted witch hazel) can worsen the condition.

Preventing Diaper Rash

To help prevent diaper rash:

  • Wash your hands before and after diaper changes

  • Change diapers frequently

  • Use plain water or mild cleansers to clean the diaper area

  • Pat the skin dry instead of rubbing

  • Use mild, fragrance-free wipes or a soft washcloth

  • Apply diaper cream or ointment with each change

  • Ensure diapers aren't fastened too tightly

  • Allow diaper-free time when possible

Changing the type of diaper or using a different detergent for cloth diapers may also help reduce the occurrence of diaper rash.

When to Seek Medical Attention

Contact your baby's doctor if the rash worsens or doesn't respond to treatment within 2-3 days, if your baby has a fever or seems sluggish, or if you notice signs of a bacterial or yeast infection.
