Overview of Eczema
Eczema is a chronic inflammatory skin condition that affects millions of people worldwide. It is characterized by dry, itchy, and red patches on the skin. Eczema is a term used to describe a group of skin conditions, rather than a single condition. It is important to note that eczema is not contagious.
Definition of Eczema
Eczema, also referred to as atopic dermatitis, is a common skin disorder that causes inflammation of the skin. It is often seen in infants and young children, but it can also affect adults. The exact cause of eczema is unknown, but it is believed to result from a combination of genetic and environmental factors.
Types of Eczema
There are several different types of eczema, each with its own unique characteristics and triggers. These include atopic dermatitis, contact dermatitis, nummular eczema, dyshidrotic eczema, and seborrheic dermatitis. Atopic dermatitis is the most common type and often begins in childhood, while adult-onset eczema usually falls under contact dermatitis.
Causes of Eczema
The exact cause of eczema is not fully understood, but it is believed to involve a complex interaction between genes and environmental factors. People with eczema often have a personal or family history of allergic conditions, such as asthma or hay fever. Environmental triggers such as irritants, allergens, certain foods, stress, and climate can also play a role in the development and exacerbation of eczema.
Prevalence of Eczema
Eczema is a widespread condition, affecting approximately 10% to 20% of children and 1% to 3% of adults worldwide. It is more prevalent in developed countries and urban areas. The incidence of eczema has been steadily increasing over the past few decades, making it a significant public health concern.
