Criteria include severely restricted food intake leading to a significantly low body weight, an intense fear of gaining weight, and a distorted perception of body image. Blood tests or other laboratory investigations may be performed to assess nutritional and overall health status, and mental health evaluations help identify any co-occurring conditions such as depression or anxiety.

Treatment Protocols: Treating anorexia nervosa usually requires a multidisciplinary approach involving medical, nutritional, and psychological support. Common strategies include: - Nutritional counseling to develop a healthy eating plan - Medical monitoring and treatment to address physical health complications - Psychological therapies such as cognitive-behavioral therapy (CBT) to modify distorted thoughts and behaviors - Family therapy, especially in adolescents, to involve loved ones in the recovery process - In some cases, medication may be prescribed to help manage underlying issues like depression or anxiety Early intervention tends to improve outcomes, emphasizing the importance of professional help at the earliest signs of the disorder.
