Complications

Complications of atopic dermatitis (eczema) may include:

• Asthma and hay fever. Eczema sometimes precedes these conditions. More than half of young children with atopic dermatitis develop asthma and hay fever by age 13.
• Chronic itchy, scaly skin. A skin condition called neurodermatitis (lichen simplex chronicus) starts with a patch of itchy skin. You scratch the area, which makes it even itchier. Eventually, you may scratch simply out of habit. This condition can cause the affected skin to become discolored, thick and leathery.
• Skin infections. Repeated scratching that breaks the skin can cause open sores and cracks. These increase the risk of infection from bacteria and viruses, including the herpes simplex virus.
• Irritant hand dermatitis. This especially affects people whose work requires that their hands are often wet and exposed to harsh soaps, detergents and disinfectants.
• Allergic contact dermatitis. This condition is common in people with atopic dermatitis.
• Sleep problems. The itch-scratch cycle can cause poor sleep quality.
