Understanding health anxiety
Health anxiety (formerly called hypochondria, now termed illness anxiety disorder) involves persistent worry about having or developing a serious illness despite reassurance and negative medical tests. It affects approximately 4-5% of the population and is associated with significant impairment and increased healthcare utilization.
The reassurance trap
Seeking reassurance — from doctors, the internet, loved ones — provides brief relief but maintains and worsens health anxiety over time. Each reassurance-seeking episode reinforces the belief that checking is necessary and that uncertainty is intolerable. Effective treatment paradoxically involves learning to tolerate uncertainty rather than eliminating it through testing.
Health anxiety and medical illness are not mutually exclusive. People with health anxiety can also have real medical conditions. The goal of treatment is not to dismiss medical concerns but to develop a more accurate and less catastrophic relationship with symptoms and uncertainty.
