Eczema: Symptoms, Causes & How to Treat and Prevent Flare-Ups

Eczema is a chronic skin condition that causes the skin to become dry, itchy, and inflamed. It is linked to other conditions such as asthma and hay fever, and is usually genetically inherited. It most commonly appears as patches on the hands, feet, ankles, wrists, and neck, and is more likely to affect children than adults. Symptoms may include dry skin, redness, itching, swelling, and blisters. Although it can range from mild to severe, it is not contagious. Treatments include prescription medications, ointments, lotions, and decreasing contact with irritants

What are the Symptoms of Eczema?

No matter which part of the skin is affected, eczema is almost always itchy. Sometimes itching will begin before any visible symptoms! Many people will develop a rash, most commonly on the face, back of the knees, wrists, hands, or feet.

Affected areas of the skin usually appear extremely dry, thick, or scaly. Depending on the tone of one's skin, the rash may initially begin to look red in color, but then turn brown. Or, if a person has a darker skin tone, eczema can affect pigmentation, making the affected area lighter or darker. 

Particularly in infants and young children, the itchy rash can produce oozing, crusting patches.

Causes of Eczema

What Causes Eczema?

The exact cause of eczema is unknown, but researchers believe that it is linked to an overactive response by the body's immune system. This autoimmune view of eczema is potentially supported by the disease commonly occurring in families with a history of allergy issues and asthma. Some doctors also say that defects in the skin barrier could force out moisture and trap germs in, causing irritation.

Eczema Triggers

Sometimes flare-ups of eczema occur in response to certain conditions or exposure to certain substances. These can include:

  • Extreme temperatures: hot temperatures; cold and dry environments.
  • Certain clothing materials: often wool or synthetic fabrics.
  • Certain household products: such as soap and laundry detergent.
  • Allergens: animal dander, dust mites, pollen, mold.
  • Food allergies.
  • Hormonal changes: eczema can worsen for women during pregnancy or in the days immediately before their period.
  • Skin infections.

For some patients, upper respiratory infections, colds, or stress may trigger the condition, or cause eczema to worsen.
