Health Anxiety Disorder

Illness Anxiety Disorder is a relatively new name for what has been more commonly referred to as Hypochondria, or Hypochondriasis. Illness Anxiety Disorder is best described as the obsessive, persistent, and irrational fear of suffering, or that one will suffer from, a disease or serious medical condition. Illness Anxiety Disorder is based on an individual's repeated misinterpretation of bodily cues, and exists despite medical reassurance that the individual does not have a disease or illness. Illness Anxiety Disorder goes beyond normal concerns with health, and can seriously impact academic and professional functioning, as well as interpersonal relationships.

It is important to realize that people with Illness Anxiety Disorder are unable to control the symptoms and do not purposely create them.

Antidepressants such as selective serotonin reuptake inhibitors (SSRIs) can help reduce the worry and physical symptoms of this disorder.
