Eczema or atopic dermatitis (AD) is a type of inflammation of the skin or dermatitis which results in itchy, red, swollen, and cracked skin. Clear fluid may come out from the affected areas, which often thicken over time. This condition typically starts in childhood with changing severity over the years. Scratching affected area worsens symptoms and people can have an increased risk of skin infections. Many people with eczema develop hay fever or asthma.
Atopic dermatitis is not contagious. Things that make it worse include wool clothing, soaps, perfumes, chlorine, dust, and cigarette smoke.
AD affects about 20% of people at some point in their lives and is more common in younger children. More than 10 million cases are reported in India per year.
How does Eczema affect your body?
Eczema affects the skin and causes red, inflamed patches that are accompanied by intense itching. This inflamed reaction has been linked to a malfunction in the body’s immune system. People with eczema have lower levels of a particular cytokine (a protein) and may also have higher levels of a different cytokine protein that prompts allergic reactions. This imbalance is most likely to blame for confusing the immune system and causing it to create the inflammation.
What are the causes of Eczema?
- Genetics– Many people with eczema have a family history of atopy. About 30% of people with AD have mutations in the gene, which increase the risk for early onset of atopic dermatitis and developing asthma.
- Hygiene hypothesis– According to this, children brought up in a modern environment are less likely to be exposed to allergens at a young age, and, when they are finally exposed, develop allergies.
- Allergens– Exposure to allergens, either from food or the environment, can exacerbate existing AD.
