Understanding Anorexia Nervosa

What Is Anorexia Nervosa?

Anorexia Nervosa is a serious mental health condition and eating disorder characterized by an obsessive desire to lose weight by refusing to eat. Classified under DSM-5 (307.1) and ICD-11 (6B80), it is associated with the highest mortality rate of any psychiatric disorder, primarily due to medical complications of starvation or suicide.

In a medico-legal context, Anorexia Nervosa frequently requires expert psychiatric evidence to address complex issues of mental capacity, particularly regarding the refusal of life-saving treatment, as well as establishing causation in clinical negligence or personal injury claims.

Diagnostic Criteria (DSM-5)

A formal diagnosis of Anorexia Nervosa requires the presence of three key criteria, causing significant physical and psychological impairment:

Restriction of Energy Intake

  • Persistent restriction of energy intake relative to requirements
  • Leading to significantly low body weight (age, sex, developmental trajectory)
  • Refusal to maintain a minimally normal weight

Fear of Weight Gain

  • Intense fear of gaining weight or becoming fat
  • Persistent behaviour that interferes with weight gain, even if at a significantly low weight

Disturbance in Self-Perception

  • Distorted view of body weight or shape
  • Undue influence of body weight on self-evaluation
  • Persistent lack of recognition of the seriousness of the current low body weight

Subtypes and Severity

  • Restricting Type: Weight loss through dieting/fasting
  • Binge-Eating/Purging Type: Recurrent episodes of purging
  • Severity based on BMI (Mild to Extreme)

Medical Complications: Bradycardia, hypotension, electrolyte imbalance, osteoporosis, and organ failure.

Prevalence and Legal Significance

Anorexia Nervosa affects approximately 0.5% to 1% of women and 0.1% of men in the UK. Expert psychiatric reports are essential for determining whether a patient has the capacity to make decisions about their nutrition and medical care, often involving the Court of Protection or the Mental Health Act 1983.

Legal cases involving Anorexia Nervosa are often highly sensitive and involve high medical risk. Our experts address specific questions regarding the intersection of mental health and the law:

Mental Capacity: Does the individual have the capacity to refuse life-sustaining treatment?
Clinical Negligence: Was there a failure to diagnose or provide adequate specialist eating disorder care?
Causation: Did a specific traumatic event or medical error cause the onset or relapse of Anorexia?
Parenting Capacity: How does the parent’s eating disorder affect their ability to care for a child?
Fitness to Plead: Does severe malnutrition or cognitive impairment affect the ability to stand trial?
Disability Status: Does the condition meet the criteria for disability under the Equality Act 2010?
Prognosis: What is the likelihood of recovery with specialist inpatient vs outpatient treatment?
Treatment Recommendations: Is MARSIPAN guidance being followed for medical stabilization?

Expert evidence in Anorexia cases often requires a dual understanding of psychiatric pathology and the physiological impacts of starvation.
