Eating disorders are neurobiological disorders rooted in the brain that cause medical and psychological issues. The main types are pica, avoidant/restrictive food intake disorder, anorexia nervosa, bulimia nervosa, and binge-eating disorder, each with distinct diagnostic criteria. Eating disorders are influenced by a combination of psychological, interpersonal, social, and biological factors including low self-esteem, feelings of lack of control, cultural pressures around body image, and genetic predispositions.
