OCD and Life Expectancy: No Direct Impact on Longevity

Obsessive-Compulsive Disorder (OCD) does not directly reduce life expectancy. It is a neuropsychiatric condition—not a degenerative or fatal disease.

Indirect Mortality Risks (Manageable)

• Suicide: Elevated in severe OCD, especially with comorbid depression. Risk reduced with treatment.
• Substance use: Self-medication → overdose, accidents.
• Medical neglect: Avoidance of healthcare due to contamination fears.
• Malnutrition: Restrictive eating rituals (rare, severe cases).
• Accidents: Distraction from intrusive thoughts (driving, cooking).

Protective Factors

• Evidence-based treatment: CBT with ERP (gold standard), SSRIs/clomipramine.
• Regular psychiatric/primary care.
• Strong support system.
• Crisis planning for severe flares.

Quality of Life ≠ Quantity

Untreated OCD severely impairs functioning, relationships, and well-being. The goal is remission and recovery—not just survival. With treatment, most people with OCD live full, normal lifespans.
