Illness Anxiety Disorder
by Rick Alan and Deanna M. Neff, MPH
Illness anxiety disorder is a health anxiety disorder. It is often chronic. A person with illness anxiety disorder is often very anxious about their health. They have fears that a real or imagined minor physical symptom is a sign of serious illness. Even when several doctors assure them otherwise, the person is convinced that they have a serious disease. Psychiatric counseling and medications can relieve some, if not all, of the anxiety and suffering. Left untreated, illness anxiety disorder can be debilitating and affect daily function.

There are no current guidelines to prevent illness anxiety disorder because the cause is not known.
