What does a baby's diaper allergy look like?

Baby diaper allergies can cause localized skin redness, swelling, and itching. As the condition worsens, pain or erosion may occur.

Diaper allergy generally refers to diaper dermatitis, which occurs when diapers are not changed promptly. Ammonia-producing bacteria in feces break down urine on wet diapers, generating ammonia that irritates the skin and leads to dermatitis. If the baby also has gastrointestinal dysfunction, low immunity, malnutrition, or other conditions that increase the frequency of diarrhea, this raises both the likelihood and duration of contact between urine/feces and the skin, indirectly promoting the development of diaper dermatitis. Cleaning the area with warm water helps improve local blood circulation and prevent worsening infection; timely diaper changes are essential. In severe cases, medications such as erythromycin ointment, mupirocin ointment, or calamine lotion may be applied under a doctor's guidance.

It is recommended to use diapers that are soft and highly breathable, and to change them frequently to prevent diaper dermatitis. If symptoms persist without improvement after some time, prompt evaluation at a hospital dermatology department is advised.
