Food, weight and shape may be used as a way of coping with, or communicating about, difficult thoughts, feelings and behaviours that a young person experiences day to day. Some young people develop eating disorders such as anorexia (where food intake is restricted), binge eating disorder and bulimia nervosa (a cycle of bingeing and purging). Other young people, particularly those of primary or preschool age, may develop problematic behaviours around food including refusing to eat in certain situations or with certain people. This can be a way of communicating messages the child does not have the words to convey.
