Illness Anxiety Disorder (Hypochondriasis)
Psychiatric treatment for excessive health anxiety and somatic symptom disorders
What Is Illness Anxiety Disorder?
Illness anxiety disorder (formerly hypochondriasis) is characterized by excessive preoccupation with having or acquiring a serious illness, despite medical reassurance. Physical symptoms may be absent or mild, but the fear of illness causes significant distress and impairs functioning. Patients cycle through reassurance-seeking behaviors — repeated doctor visits, medical tests, internet health searches — which temporarily reduce anxiety but reinforce the cycle long-term.
This condition is closely related to other anxiety and obsessive-compulsive spectrum disorders. It is often misdiagnosed or dismissed, leaving patients feeling invalidated. Proper psychiatric evaluation identifies the pattern and opens effective treatment pathways.
Signs & Symptoms
- Preoccupation with having or developing a serious, undiagnosed illness
- Excessive body checking or monitoring for signs of illness
- Excessive internet health searches (cyberchondria)
- Frequent medical appointments or avoidance of medical care due to fear of diagnosis
- Medical reassurance provides only temporary relief before anxiety returns
- Significant distress and impairment in daily functioning
- Preoccupation persists for 6 months or more
Treatment Approaches
Cognitive Behavioral Therapy (CBT) is the most effective treatment for illness anxiety — specifically targeting catastrophic health interpretations, reassurance-seeking behaviors, and avoidance. Exposure and Response Prevention (ERP) — the same technique used for OCD — helps patients tolerate health-related uncertainty without compulsive reassurance-seeking.
SSRIs (particularly those effective for OCD and anxiety) have meaningful evidence for illness anxiety disorder. The combination of CBT and appropriate medication produces the best outcomes. Dr. Agresti provides both psychotherapy and medication management in the same practice — eliminating the fragmentation common in standard psychiatric care.

Health-conscious behavior involves reasonable precautions and appropriate medical follow-up. Illness anxiety disorder is characterized by persistent, excessive preoccupation with having or developing a serious illness despite negative medical tests and physician reassurance. The key distinction is that the worry causes significant distress, impairs daily functioning, and persists for six months or more.
Reassurance-seeking functions similarly to a compulsion in OCD. Each negative test result provides brief relief, but the underlying anxiety pattern remains intact, and the brain quickly generates a new health worry or reinterprets old symptoms. Treatment with Exposure and Response Prevention (ERP) helps patients learn to tolerate health uncertainty without compulsive reassurance-seeking.
Illness anxiety disorder involves preoccupation with having a serious illness with minimal or no physical symptoms. Somatic symptom disorder involves one or more distressing physical symptoms accompanied by excessive thoughts, feelings, or behaviors related to those symptoms. Both conditions respond to psychiatric treatment, and Dr. Agresti evaluates for the full spectrum of somatic and anxiety-related disorders.
CBT is the most evidence-based treatment for illness anxiety disorder. It works by identifying and challenging catastrophic health interpretations, reducing body-checking and reassurance-seeking behaviors, and building tolerance for health-related uncertainty. Combined with appropriate SSRI medication, CBT produces lasting improvement in the majority of patients.
Yes. Illness anxiety disorder shares significant overlap with OCD, particularly the obsessive worry and compulsive reassurance-seeking cycle. Both conditions respond to the same treatments: SSRIs and Exposure and Response Prevention therapy. Dr. Agresti is experienced in treating both conditions and provides integrated medication management and psychotherapy in extended appointments.
