Eczema, also known as atopic dermatitis, is a chronic skin condition that causes dry, itchy, and inflamed patches of skin. It is a common condition that can occur at any age, but it often starts in infancy and childhood. Eczema is not contagious, and its exact cause is unknown, but it is believed to develop from a combination of genetic and environmental factors. Symptoms of eczema can flare up if you contact an irritant or an allergen, and scratching the affected area can make the symptoms worse. There is no cure for eczema, but there are treatments available to help manage symptoms, including at-home remedies, over-the-counter medications, and prescription medications. It is important to see a dermatologist or healthcare provider as soon as you start to see signs of eczema to develop a symptom management plan and stop future flare-ups.
