Diaper Rash
Understanding Severe Diaper Rash
Severe or chronic diaper rash occurs when irritation, moisture, and friction in the diaper area cause ongoing redness, inflammation, and discomfort. Unlike mild diaper rash, which clears up with basic care, chronic cases can persist for weeks or repeatedly return. At Signature Dermatology in Fort Worth, we help parents identify the underlying causes and provide effective treatments that restore comfort and protect their baby’s delicate skin.
This condition refers to persistent or intense irritation and inflammation of the skin in the diaper area. While occasional mild diaper rash is common in babies, severe or chronic cases can be more challenging to manage and may require medical attention.
Common Causes and Symptoms
Several factors can contribute to this, including:
- Prolonged exposure to wetness: Leaving a wet or soiled diaper on for too long can irritate the skin, leading to diaper rash.
- Friction: Rubbing and chafing from the diaper against the skin can exacerbate irritation, especially if the diaper is too tight.
- Irritants: Contact with irritants such as soaps, lotions, fragrances, or certain diaper materials can trigger or worsen this.
- Fungal or bacterial infections: Yeast infections (such as candidiasis) or bacterial infections can develop in the moist environment of the diaper area, leading to more severe diaper rash.
- Sensitivities or allergies: Some babies may have sensitivities or allergies to certain diapering products, wipes, or foods, which can contribute to this.
Chronic conditions may be triggered by yeast or bacterial infections, sensitive skin, or reactions to certain diapers or wipes. Symptoms can include redness, swelling, blisters, or oozing areas that make diaper changes painful. If the rash spreads beyond the diaper area or does not improve with over-the-counter creams, professional care is recommended.
Diagnosis and Treatment
Our dermatologists carefully examine the affected skin to determine the cause and prescribe appropriate therapies, such as antifungal creams, mild corticosteroids, or barrier ointments. We also provide guidance on diapering techniques, gentle cleansers, and preventive care to avoid recurrence.
At Signature Dermatology, our goal is to relieve irritation quickly and help your baby’s skin heal naturally with safe, effective, and compassionate care.
