Which of the following is a type of eating disorder?

Anorexia nervosa is indeed a type of eating disorder characterized by an intense fear of gaining weight and a distorted body image that leads to restrictive eating and significant weight loss. It can have severe physical and mental health consequences and is classified in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) as a distinct type of eating disorder, highlighting its unique features and the specific interventions required for treatment.

In contrast, social anxiety disorder, schizophrenia, and obsessive-compulsive disorder are classified as mental health disorders but do not specifically pertain to eating behaviors or diet. Social anxiety disorder involves an excessive fear of social situations, schizophrenia is a severe mental disorder that affects how a person thinks, feels, and behaves, and obsessive-compulsive disorder involves unwanted, intrusive thoughts and repetitive behaviors. Each of these disorders has its own distinct characteristics and treatment approaches, separate from the defined parameters of eating disorders like anorexia nervosa.
