Atopic dermatitis (also called eczema) is a skin problem that causes intense itching and a red, raised rash. In severe cases, the rash develops clear fluid-filled blisters. The rash is not contagious. You can't catch it from others. People with this condition seem to have sensitive immune systems that are likely to react to things that cause allergies. The immune system is the body's way of fighting infection. There is no cure for atopic dermatitis, but you may be able to control it with care at home. ➤ What causes it? The causes are unclear. Most people who have it have a personal or family history of allergies. The skin inflammation that causes the atopic dermatitis rash is considered a type of allergic response. It can be triggered by allergens, harsh soaps, temperature changes, stress, and excessive washing. ➤ What are the symptoms? Atopic dermatitis starts with very itchy, dry skin. The skin becomes red and irritated by scratching. Little blisters may appear and ooze fluid or crust over. A recurring rash can become tough and thick from constant scratching. The areas most often affected are the face, scalp, neck, arms, and legs. ➤ What is allergic dermatitis? Allergies are an overreaction of the body's natural defense system that helps fight infections (immune system). The immune system normally protects the body from viruses and bacteria by producing antibodies to fight them. In an allergic reaction, the immune system starts fighting substances that are usually harmless (such as dust mites, pollen, or a medicine) as though these substances were trying to attack the body. This overreaction can cause a rash, itchy eyes, a runny nose, trouble breathing, nausea, and diarrhea. An allergic reaction may not occur the first time you are exposed to an allergy-producing substance (allergen). For example, the first time you are stung by a bee, you may have only pain and redness from the sting. If you are stung again, you may have hives or trouble breathing. This is caused by the response of the immune system. Many people will have some problem with allergies or allergic reactions at some point in their lives. Allergic reactions can range.
