Atopic dermatitis (AD), also known as eczema, is a chronic skin condition that causes dryness, intense itching, and red rashes. In severe cases, the rash may form fluid-filled blisters.
AD is not contagious and is very common among children. While some outgrow it with age, others continue to experience symptoms into adulthood. Additionally, adults who never had eczema as children can develop it later in life.
Symptoms of Atopic Dermatitis
AD symptoms usually appear in childhood and range from mild to severe. The condition flares up periodically, alternating between active episodes and remission phases.
The rash can be localized or widespread, affecting different parts of the body. Common symptoms include:
Severe itching, often worsening at night.
Dry, scaly skin patches.
Red rashes.
Blisters.
Skin thickening and roughness due to repeated scratching.
Cracking and potential bleeding of the skin.
Light or dark skin patches.
Note: On lighter skin, eczema typically appears red, whereas on darker skin tones, it may appear purple, gray, or difficult to detect.
Common Sites of Eczema Based on Age
Infants → Face (especially the cheeks), scalp, hands, and feet.
Children → Inner elbows and knees.
Adults → Behind the knees, inside the elbows, back of the neck, face, and sometimes around the eyes.
The severity of symptoms depends on how much of the skin is affected, how long the condition persists, the intensity of itching, and whether the rash becomes infected.
Complications of Atopic Dermatitis
AD can lead to several complications, such as:
Persistent itching and scaling.
Skin infections due to frequent scratching.
Sleep disturbances caused by nighttime itching.
Treatment of Atopic Dermatitis
Although there is no permanent cure, symptoms can be managed effectively through the following measures:
Regular use of moisturizers to keep the skin hydrated.
Avoiding triggers like certain soaps, detergents, pet dander, and irritants.
Preventing scratching by covering the affected area or wearing gloves (especially for children).
Following prescribed medications such as topical corticosteroids or antihistamines.
Taking short, lukewarm showers instead of hot baths.
Using ultraviolet (UV) therapy in severe cases.
Prevention of Atopic Dermatitis Flare-ups
Since the exact cause of AD remains unknown, complete prevention is not possible. However, some steps can help reduce flare-ups:
Identifying and avoiding triggers, such as certain fabrics, allergens, and harsh soaps.
Maintaining skin hydration using creams or ointments.
Taking warm (not hot) showers and using mild, fragrance-free soap.
Patting the skin dry with a soft towel and applying moisturizer immediately after bathing.
