Metallophobia: Fear of Metal—Symptoms, Causes & Treatment Options

Metallophobia is a specific phobia (DSM‑5: 300.29) characterized by marked fear/anxiety about metal objects.

Symptoms

• Immediate anxiety/panic on exposure or anticipation.
• Avoidance (refusing to touch doorknobs, jewelry, cutlery, coins).
• Physical: tachycardia, sweating, trembling, dyspnea, nausea, derealization.
• Recognition that fear is excessive (in adults).
• Duration ≥6 months; functional impairment.

Etiology

• Traumatic conditioning (injury from metal).
• Vicarious learning (observing fear).
• Information transmission (warnings about tetanus, toxicity).
• Sensory hypersensitivity (cold, texture, sound of metal).
• Comorbid: OCD (contamination), autism spectrum (sensory).

Treatment

1. CBT with Exposure & Response Prevention (ERP): Hierarchical exposure (photos → touching coated → bare metal). Gold standard.
2. Cognitive restructuring: Challenge catastrophic beliefs (e.g., “touching metal causes poisoning”).
3. Medication: SSRIs if comorbid anxiety/depression; beta‑blockers for performance situations.
4. Relaxation training: Applied tension for vasovagal component.

Prognosis good with specialized CBT; remission rates 70–90%.
