DEFINITION
HEALTH ANXIETY SYNDROME is a condition characterized by excessive preoccupation with health, disease, bodily sensations, or the possibility of serious illness despite absent, mild, benign, or medically explained symptoms.
Individuals experience persistent fears regarding physical health, heightened awareness of normal bodily sensations, catastrophic interpretations of benign symptoms, repeated reassurance seeking, excessive health-related checking, frequent medical consultations, or compulsive health-information searching.
The central pathology is not the presence of disease itself, but the persistent misinterpretation of bodily signals as evidence of serious illness and the inability to tolerate uncertainty regarding health status.
Within the SCF-RDOS framework, Health Anxiety Syndrome is conceptualized as a health-threat processing disorder involving dysregulation across interoceptive monitoring systems, threat-detection networks, uncertainty-processing pathways, emotional-regulation mechanisms, reassurance-seeking circuits, and illness-belief maintenance systems.
ETIOPATHOGENIC CORE
Primary Pathogenic Theme
Normal bodily sensations, minor symptoms, or health-related information become catastrophically interpreted as indicators of serious disease, resulting in chronic anxiety, reassurance-seeking behaviors, and persistent illness preoccupation.

Threat-Detection Hyperactivity | Illness fear amplification |
Interoceptive Hypervigilance | Excessive body monitoring |
Catastrophic Interpretation Bias | Symptom misinterpretation |
Intolerance of Uncertainty | Persistent health concerns |
Reassurance-Seeking Dependency | Anxiety maintenance |
Health Information Overexposure | Fear reinforcement |
Emotional Dysregulation | Anxiety persistence |
Illness Belief Consolidation | Chronic symptom focus |
