Definition of Eczema:

Eczema is a chronic skin disorder that involves scaly and itchy rashes.

Causes, incidence, and risk factors:

Eczema is due to a hypersensitivity reaction (similar to an allergy) in the skin, which leads to long-term inflammation. The inflammation causes the skin to become itchy and scaly. Long-term irritation and scratching can cause the skin to thicken and have a leather-like texture.

Eczema is most common in infants. The condition tends to run in families.

People with eczema often have a family history of allergic conditions such as asthma, hay fever, or eczema.

The following can make eczema symptoms worse:

• Dry skin
• Exposure to environmental irritants
• Exposure to water
• Stress
• Temperature changes
