illness anxiety disorder
in DSM–5, a disorder characterized by high anxiety about one’s health, by excessive preoccupation with having an illness or acquiring it, and by behaviors associated with the presumed or feared condition (e.g., repeatedly checking oneself for possible signs of illness), yet with no significant somatic symptoms that would warrant such concern. One of two replacement diagnoses for hypochondriasis, illness anxiety disorder is determined based only on this set of criteria and does not also apply to the presence of both high health anxiety and significant somatic symptoms. See somatic symptom disorder.
