Characteristic signs of inadequate energy (caloric) intake observed in patients with anorexia nervosa that are due to starvation-induced changes include the following:

  • Hypothermia

  • Acrocyanosis

  • Resting bradycardia (resting heart rate often 40-49 beats per minute)

  • Hypotension

  • Orthostatic lowered blood pressure or pulse

  • Loss of muscle mass

  • Low blood glucose (impaired insulin clearance)

  • Low parathyroid hormone levels

  • Elevated liver function

  • Low white blood cell (WBC) count

Behaviorally, a patient may demonstrate a flat affect and display psychomotor retardation, especially in the later stages of the disease.
