The rashes can cover only a few square inches or most of the body. Severity ranges from mild irritation to a painful scaly crust that oozes bacteria-charged fluid. Children are particularly susceptible, but most outgrow the disease by the age of two. For a child, the pain, taunting, and inability to play in the schoolyard can combine to make their lives almost unbearable. Anxiety, stress, and depression can bring on the disorder or make it worse.
Hereditary factors play an important role.
Eighty percent of those with eczema have family members with the disease. Asthma and hay fever similarly overlap in families with eczema. But it's the many unknown factors that prevent full understanding and cure for the disease. Sadly, outside of children's food allergies which often exist with the condition, we usually can't pin down the cause. As a result, treatment often seeks to minimize the symptoms of the disease.
