The document discusses biological explanations for Anorexia Nervosa (AN), specifically focusing on theories related to hypothalamus dysfunction. Two key clinical characteristics of AN include low body weight and fear of gaining weight. The hypothalamus, described as the brain's "weight thermostat", is thought to be implicated in causing AN. When weight is low, the hypothalamus is activated to stimulate eating, while when weight is high it stimulates eating to reduce weight. The Hypothalamus Dysfunction theory proposes that the hypothalamus is not functioning properly in those with AN, leading to issues with appetite and weight regulation.
