Dermatitis

What is Dermatitis?
Dermatitis is a general term describing inflammation of the skin. It usually involves an itchy rash on swollen, reddened skin.

It is a common condition that is not contagious, but it can make you feel uncomfortable and self-conscious. Common forms include Eczema, Dandruff, and allergic rashes.

Common Types & Symptoms

Because "dermatitis" is a broad term, symptoms depend on the specific type you have:

1. Atopic Dermatitis (Eczema)

Usually begins in infancy. It appears as a red, itchy rash where the skin flexes (inside elbows, behind knees, front of neck). If scratched, it can leak fluid and crust over.

2. Contact Dermatitis

Occurs on areas of the body that have touched an irritant or allergen (like poison ivy, jewelry containing nickel, or harsh soaps). It causes burning, stinging, itching, or blisters.

3. Seborrheic Dermatitis

Causes scaly patches, red skin, and stubborn dandruff. It usually affects oily areas of the body, such as the face, upper chest, and back. In infants, this is known as "Cradle Cap."

Causes

Causes vary by type:

• Genetics (Atopic): Often runs in families with a history of asthma or hay fever.
• Allergens (Contact): Direct contact with irritants like perfumes, cosmetics, or metals.
• Yeast/Oil (Seborrheic): A yeast naturally found on the skin can overgrow in oily areas.

Complications

⚠️ INFECTION RISK
The biggest risk is infection. Scratching the itchy rash can create open sores, allowing bacteria to enter.

See a doctor if: The skin becomes painful, feels hot, streaks red, or oozes yellow pus.

Diagnosis

Doctors can usually diagnose dermatitis by examining the skin. To find the specific trigger, they may use:

• Patch Testing: Small amounts of potential allergens are applied to the skin under adhesive patches to see if a reaction occurs.

Treatment

Treatment focuses on healing the skin barrier and stopping the itch.

1. Medical Treatments

• Corticosteroid Creams: To reduce inflammation and itching.
• Antihistamines: Oral medication to reduce severe itching (especially at night).
• Light Therapy (Phototherapy): Exposing skin to controlled amounts of natural or artificial light.

2. Self-Care & Prevention

• Moisturize: Apply lotion while skin is still damp after a bath to lock in moisture.
• Avoid Irritants: Use unscented laundry detergents and soaps.
• Wet Compresses: Apply cool, wet cloths to soothe inflamed skin.
• Don't Scratch: Cover the itch with a dressing if you can't stop scratching.
