Social withdrawal, irritability, preoccupation with food, and depression appear to be effects rather than causes of anorexia.

These symptoms are typically seen as consequences of anorexia rather than the root causes of the disorder. An individual with anorexia may withdraw socially due to fear of judgement or feeling self-conscious about their body. Irritability may be caused by hunger and low energy levels, while preoccupation with food is a natural response to restriction. Depression may be a result of the physical and emotional toll of the disorder.
