Almost 31.6 per cent of people in the United States are at different stages of eczema. Atopic dermatitis is also termed is another term for eczema. The word atopic refers to the collection of diseases that involves the immune system such as asthma and hay fever. The word dermatitis refers to the inflammation of the skin. The symptoms of such atopic dermatitis vary depending on the age of the person. This condition is mostly seen in infants. Dry and scaly patches appear on the skin and such patches are itchy.

Rashes under and over 2 years old till puberty:
- Rashes on the scalp, cheeks, behind creases of elbows or knees.
- Rashes bubble up and then leaks fluid. There might be too much itchiness thereby affecting sleep.
Over time, the following happens:
- Rashes becoming bumpy, either light or dark in colour.

The specific cause of eczema is not known. However, according to common belief, it is caused due to a combination of environmental and genetic factors. This disease is not contagious and children are more likely to develop such condition if a parent has had the same or similar condition. The risk increases if both the parents have had an atopic disease. There are a few environmental factors that instigate the symptoms and these are:
- Irritants such as detergents, shampoos, soaps, fruits, meat, vegetables.
- Allergens such as pets, dust mites and dandruff.
- Very hot or very cold weather along with high or low humidity or perspiration from too much exercise.
- Foods such as nuts, seeds, dairy products, wheat, soy products can result in eczema flare-ups.
- Women can experience the symptoms, even more, when the hormone levels are changing.
- Even though stress is not a direct cause but it might make symptoms worse.
