Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition that affects millions of people worldwide. It is characterised by dry, itchy, and inflamed skin, which can lead to discomfort, embarrassment, and even infection. In this article, we will delve into the causes, symptoms, treatments, and prevention strategies for skin eczema, providing a comprehensive guide for those affected by this condition.
Causes of Eczema
While the exact cause of eczema is still unknown, research suggests that it is an interaction between genetic and environmental factors that leads to an overactive immune response. This response causes the skin barrier to become dry and itchy, leading to the characteristic symptoms of eczema.
- Genetic Component: A family history of eczema, allergies, and asthma can increase the risk of developing eczema.
- Environmental Triggers: Irritants such as soaps, detergents, and fragrances can trigger eczema, as can allergens like pollen, dust mites, and pet dander.
- Stress: Stress can exacerbate eczema symptoms, and some people may experience eczema as a result of stress.
Symptoms of Eczema
Eczema symptoms can vary in severity and location, but common symptoms include:
- Dry, itchy, and inflamed skin
- Redness and swelling
- Blisters and rashes
- Crusting and oozing
- Skin infections
Types of Eczema
There are several types of eczema, each with its own set of symptoms and triggers. The most common types include:
- Atopic Dermatitis: The most common type of eczema, characterized by dry, itchy skin and a family history of allergies and asthma.
- Contact Dermatitis: Caused by skin contact with irritants or allergens, such as soaps, detergents, or metals.
