Allergic diseases often begin in childhood and develop into adults over a chronic course. Children who become adults with chronic diseases need to understand their illness and to be able to lead their independent lives. However, children who develop symptoms in early childhood and are taking medication and care continuously may grow up with an unclear understanding of the disease, medication and care. They may face problems such as interruption of treatment or inadequate care. We discuss self-reliance support for children and families with allergic diseases in the context of patient education toward the transition to adult medical care, with the view of growth and development.
