Clinical Causes: Genetic predisposition, which may influence appetite regulation and body image perceptions. Psychological factors such as perfectionism, low self-esteem, and anxiety disorders. Societal and cultural pressures emphasizing thinness and ideal body standards. Family dynamics, including overemphasis on appearance or unhealthy weight-related conversations. Trauma or stressful life events that trigger disordered eating behaviors.

Key Symptoms: Significantly restricted food intake, leading to a body weight that is less than what is considered healthy for age and height, but still with a BMI of 17 kg/m2 or higher in this mild case. Preoccupation with weight, dieting, and body image. Distorted perception of body shape and size. Decreased muscle mass and overall body fat leading to feeling cold or fatigued. Persistent fear of gaining weight despite being underweight or at a normal weight. Anxiety surrounding eating, weight, or appearance. Possible physical signs such as hair thinning, dry skin, or menstrual irregularities.

Diagnosis Path: Diagnosis involves a comprehensive assessment by a healthcare professional, including a physical examination, detailed medical history, and psychological evaluation. Measurement of BMI is critical; in this mild form, the BMI will be 17 kg/m2 or higher. The health provider will also look for signs of nutritional deficiency and examine behavioral patterns related to eating and body image.

Treatment Protocols: Nutritional counseling to establish regular eating habits and ensure adequate nutritional intake. Psychotherapy, such as cognitive-behavioral therapy (CBT), to challenge distorted beliefs about weight and shape. Medical monitoring to manage physical health issues related to restricted eating. Family therapy, if applicable, to support recovery and improve communication. In some cases, medication may be considered to treat associated conditions like anxiety or depression.
