Anorexia Nervosa and Addiction: Understanding Co-occurring Conditions

How Anorexia Nervosa and substance use disorders interact — why they co-occur and integrated treatment approaches.

Anorexia Nervosa and addiction frequently co-occur — each substantially increases the risk for the other, and both must be addressed for lasting recovery.

Why Anorexia Nervosa and Addiction Occur Together

The relationship is bidirectional:

  • Many people use substances to self-medicate anorexia nervosa, creating dependency
  • Substances temporarily relieve anorexia nervosa symptoms but ultimately worsen them
  • Addiction itself creates the neurological conditions that drive anorexia nervosa
  • Shared risk factors (trauma, genetics, stress) predispose to both

The Challenge of Treating Both Anorexia Nervosa and Addiction

Treating only one condition while ignoring the other leads to poor outcomes. Integrated dual-diagnosis treatment addressing both simultaneously is most effective.

Treatment for Co-occurring Anorexia Nervosa and Addiction

Integrated programs address anorexia nervosa and substance use together through:

  • Trauma-informed therapy (often underlying both)
  • Medication-assisted treatment where appropriate
  • Peer support that understands both conditions
  • Addressing the anorexia nervosa symptoms that drive substance use
