Atopic dermatitis is a long-term inflammatory skin condition that affects the body's largest organ, the skin. It is also known as eczema, a chronic skin disorder that can cause redness, intense itching, and scaly, thickened patches of skin. Although atopic dermatitis affects the skin, it can also have an effect on other organs in the body, including the eyes, nose, throat, lungs, and digestive system.
Effects on the Skin
Atopic dermatitis is characterized by an itchy, scaly rash that can be very uncomfortable. In some cases, the rash may become infected or raw from scratching. Symptoms can range from mild to severe and can appear on any area of the body. Common areas where the rash is found include the neck, face, elbows, knees, and ankles.
Effects on the Eyes
Atopic dermatitis can cause inflammation of the eyes, known as conjunctivitis. Symptoms of conjunctivitis can include redness, itchiness, and swelling of the eyelids. The condition can also cause dry eyes and blurred vision.
Effects on the Nose and Throat
Atopic dermatitis can cause inflammation of the nose and throat, leading to nasal congestion, sneezing, and postnasal drip. It can also cause a sore throat due to irritation from the inflammation.
Effects on the Lungs
Atopic dermatitis can cause inflammation of the lungs, making it difficult to breathe. This can lead to a condition known as asthma, which can cause wheezing, chest tightness, and difficulty breathing.
Effects on the Digestive System
Atopic dermatitis can cause inflammation of the digestive system, leading to a condition known as gastroenteritis. Symptoms of gastroenteritis can include diarrhea, nausea, vomiting, and abdominal pain.
