A somatic symptom disorder, formerly known as a somatoform disorder,[1][2][3] is a mental disorder characterized by physical symptoms that suggest physical illness or injury – symptoms that cannot be explained fully by a general medical condition or by the direct effect of a substance, and are not attributable to another mental disorder (e.g., panic disorder).[4] In people who have a somatic symptom disorder, medical test results are either normal or do not explain the person's symptoms, and history and physical examination do not indicate the presence of a medical condition that could cause them. Patients with this disorder often become worried about their health because doctors are unable to find a cause for their symptoms. This may cause severe distress. Preoccupation with the symptoms may portray a patient's exaggerated belief in the severity of their ill-health.[5] Symptoms are sometimes similar to those of other illnesses and may last for several years. Usually, the symptoms begin appearing during adolescence, and patients are diagnosed before the age of 30 years.[6] Symptoms may occur across cultures and gender.[6] Other common symptoms include anxiety and depression.[6] An individual with somatic symptom disorder might experience legitimate physiological changes (e.g., heart rate, blood pressure) presented as interpretations of their symptoms. [7] A diagnoses of somatic symptom disorder requires that the subject have recurring somatic complaints for at least six months.[6]

Somatic symptom disorders are not the result of conscious malingering (fabricating or exaggerating symptoms for secondary motives) or factitious disorders (deliberately producing, feigning, or exaggerating symptoms) – sufferers perceive their plight as real.[8] Various laboratory tests, physical examinations, and surgeries on these individuals show no evidence supporting the idea that these exaggerating symptoms are present.[6] Mental disorders are treated separately from physiological or neurological disorders. Somatic symptom disorder is difficult to diagnose and treat since doing so requires psychiatrists to work with neurologists on patients with this disorder.[6] Those that do not pass the diagnostic criteria for a somatic symptom disorder but still present physical symptoms are usually referred to as having "somatic preoccupation".[5]

Recognized disorders

Somatic symptom disorders are a group of disorders, all of which fit the definition of physical symptoms that mimic physical disease or injury for which there is no identifiable physical cause. As such, they are a diagnosis of exclusion. They are recognized in the Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association as the following:[4]

  • Conversion disorder: A somatic symptom disorder involving the actual loss of bodily function such as blindness, paralysis, and numbness due to excessive anxiety
  • Illness anxiety disorder: A somatic symptom disorder involving persistent and excessive worry about developing a serious illness. This disorder has recently gone under review and has been altered into three different classifications.[citation needed]
  • Body dysmorphic disorder: wherein the afflicted individual is concerned with body image, and is manifested as excessive concern about and preoccupation with a perceived defect of their physical appearance.
  • Pain disorder
  • Undifferentiated somatic symptom disorder – only one unexplained symptom is required for at least 6 months.

Included among these disorders are false pregnancy, psychogenic urinary retention, and mass psychogenic illness (so-called mass hysteria).

  • Somatoform disorder Not Otherwise Specified (NOS)[9]

The ICD-10 classifies conversion disorder as a dissociative disorder.

Somatization disorder is a mental disorder was recognized in the DSM-IV-TR classification system, but in the latest version DSM-V, it was combined with undifferentiated somatoform disorder to become somatic symptom disorder, a diagnosis which no longer requires a specific number of somatic symptoms.[10] Still, ICD-10, the latest version of the International Statistical Classification of Diseases and Related Health Problems, still includes somatization syndrome.[11]

Proposed disorders

Additional proposed somatic symptom disorders are:

  • Abridged somatization disorder[12] – at least 4 unexplained somatic complaints in men and 6 in women
  • Multisomatoform disorder[6] – at least 3 unexplained somatic complaints from the PRIME-MD scale for at least 2 years of active symptoms

These disorders have been proposed because the recognized somatic symptom disorders are either too restrictive or too broad. In a study of 119 primary care patients, the following prevalences were found:[13]

  • Somatization disorder – 1%
  • Abridged somatization disorder – 6%
  • Multisomatoform disorder – 24%
  • Undifferentiated somatoform disorder – 69%

Diagnostic criteria

Each of the specific somatic symptom disorders has its own diagnostic criteria.


In the opinion of Allen Frances, chair of the DSM-IV task force, the DSM-5's new somatic symptom disorder brings with it a risk of mislabeling a sizable proportion of the population as mentally ill. “Millions of people could be mislabeled, with the burden falling disproportionately on women, because they are more likely to be casually dismissed as ‘catastrophizers’ when presenting with physical symptoms.”[14]
