Kids Home > Causes of Diaper Rash
The causes of diaper rash are categorized into those related to the diaper and those unrelated to diaper use. Some of the possible causes related to or made worse by diaper use include irritation, bacteria or yeast growth, an allergic reaction. Causes that are not related to the diaper itself include skin conditions such as scabies, psoriasis, atopic dermatitis, and seborrheic dermatitis.
What Causes Diaper Rash?
Causes Related to the Diaper
- Irritation: This is the most common diaper rash cause and is known medically as irritant dermatitis. Diapers naturally create a moist environment, which increases the chance for skin damage. When skin damage occurs, it makes it easier for harsh and acidic elements like urine and feces to irritate and damage the skin, causing a rash.
- Bacteria or yeast growth: The inside of a baby's diaper is the perfect environment for infections to grow. If the skin has already become irritated from extended exposure to the contents of a dirty diaper, bacteria or yeast could grow inside the moist and warm diaper.
- Allergic reaction to the diaper or sensitive skin: An allergic reaction can happen to a dye in the diaper. A baby's skin can also be sensitive to a particular baby wipe, powder, or lotion, or to a certain detergent, bleach, or fabric softener (for cloth diapers). This is a less common cause of a diaper rash, although it is not known how often it occurs.
