Diaper rash in infants

Diaper rash is an inflammatory skin condition in infants that occurs in the diaper area. It is characterized by redness and may be accompanied by spots, bumps, blisters, erosions, and peeling skin. The affected skin can be painful and sensitive.

Causes of diaper rash

Infant skin is thinner, more delicate, and less resistant than adult skin. The diaper area—including the buttocks, thighs, and genital region—is exposed for long periods to irritating substances such as urine and feces. Although diapers are becoming increasingly comfortable, they must retain moisture to function properly, which limits air exposure. This lack of ventilation promotes irritation and inflammation.

The causes of diaper rash are often complex. In most cases, multiple factors contribute simultaneously; it is rare for it to be caused by a single problem. Each baby reacts differently, so this condition must be evaluated individually. In some cases, the cause is mechanical skin damage, in others an infection or an allergic reaction.

Risk factors

• Allergy to materials or substances used in diapers or skin care products
• Frequent diarrhea or loose stools
• Insufficient hygiene or infrequent diaper changes
• Reduced immunity, for example due to prolonged antibiotic use
• Alkaline urine that irritates the skin
• Presence of yeast (such as Candida) in stools
• Rubbing of the diaper against the skin
• Prolonged exposure to moisture, which causes maceration of the skin
• Urinary tract abnormalities

Symptoms and progression

Diaper rash usually begins with skin redness, which can progress to bright red patches accompanied by scaling. In more severe cases, swelling develops and skin lesions may form, such as bumps, blisters, or weeping sores. These changes may indicate a yeast infection, and a bacterial superinfection may also occur.

Diaper rash causes pain, itching, and general discomfort. Babies may become restless, cry during diaper changes, sleep poorly, and refuse intimate care. Persistent redness that does not improve with protective creams is an important warning sign.

Treatment of diaper rash

At the first sign of diaper rash, proper hygiene is essential. Change diapers frequently to avoid prolonged contact between the skin and urine or fecal matter. Use mild, non-irritating products and check if diapers, wipes, or skin care products may cause an allergic reaction.

Handle the affected skin with great care. During this period, infants can be irritable, difficult, eat less, and have sleep disturbances. In mild cases, avoiding allergens, keeping the skin clean, and regularly allowing diaper-free time to let the skin breathe may be sufficient.

If symptoms do not improve or worsen—such as the appearance of blisters, scabs, or sores—a doctor should be consulted. The doctor will assess the cause and may recommend topical treatments, including antifungal or antibacterial medications. In some cases, anti-inflammatory creams are used.

Prevention: The ABCs of diaper rash

• Change diapers frequently
• React quickly to skin changes
• Allow baby's skin to air dry regularly
• Use gentle, non-allergenic skincare products
• Choose diapers of the correct size
• Clean the diaper area with water and mild baby soap
• Limit the use of pre-moistened wipes
• Use protective products (such as zinc oxide cream) at the first signs of irritation
• Dry the skin thoroughly after washing
• Avoid overheating the baby
• Consult a doctor immediately if skin peeling, blisters, sores, or fever occur
