Anorexia nervosa (AN) is a serious, biologically based eating disorder characterized by restrictive eating, intense fear of weight gain, and disturbances in body perception. It affects both physical and mental health and involves complex interactions among the brain, metabolism, hormones, the immune system, and the gut. AN is not a choice, and recovery requires medical, psychological, and social support.

Anorexia nervosa affects people of all genders, ages, races, and backgrounds. It often begins during adolescence but can occur at any stage of life. While historically underrecognized in some groups, research shows that men, older adults, and individuals across cultures are significantly affected. Genetics, biology, and environment all contribute to risk.

Signs of AN can be physical, psychological, and behavioral, including:

  • Restrictive eating or rigid food rules

  • Significant weight loss or difficulty maintaining weight

  • Intense fear of gaining weight

  • Distorted body image

  • Anxiety, perfectionism, or obsessive behaviors

  • Fatigue, dizziness, or feeling cold frequently
