"Somatic symptom disorder (SSD formerly known as "somatization disorder" or "somatoform disorder") is a form of mental illness that causes one or more bodily symptoms, including pain. The symptoms may or may not be traceable to a physical cause"
If you are not aware @wigglethemouse (and apologies if you are):
for the WHO's forthcoming ICD-11, the single category replacement for most of ICD-10's Somatoform disorders and F48.0 Neurasthenia has drawn heavily on DSM-5's Somatic symptom disorder construct.
ICD-11's new Bodily distress disorder is conceptually very close to SSD and SSD is listed under Synonyms.
For descriptions and criteria for SSD, see also:
DSM-5 Somatic symptom disorder: https://www.psychiatry.org/File Library/Psychiatrists/Practice/DSM/APA_DSM-5-Somatic-Symptom-Disorder.pdf
Somatic Symptom Disorder

Joel E. Dimsdale had chaired the DSM-5 Somatic Symptom Disorders Work Group. In this AJP article, Dimsdale writes (my bolding):
https://ajp.psychiatryonline.org/doi/pdf/10.1176/appi.ajp.2013.13050589
"...Note that the diagnosis of somatic symptom disorder in this case is based on criteria that are present rather than lack of explanation of symptoms; furthermore, these criteria focus on territory familiar to psychiatrists and psychologists—thoughts, feelings, and behaviors. The removal of the emphasis on medically unexplained symptoms allows a focus on patient suffering without questioning its legitimacy or “reality.” Furthermore, finding somatic symptoms of unclear etiology is not sufficient to make this diagnosis. In the absence of abnormal thoughts, feelings, and behaviors, patients with irritable bowel syndrome, chronic fatigue, or fibromyalgia would not qualify for a diagnosis of somatic symptom disorder."
For the APA's SSD field trials, three groups were studied:
488 healthy patients; a "diagnosed illness" group of 205 patients with cancer and malignancy (some in this group were said to have severe coronary disease) and a "functional somatic" group comprising 94 people with "irritable bowel" and "chronic widespread pain" (a term often used synonymously with fibromyalgia).
15% of the cancer and malignancy group met the SSD criteria when "one of the B type criteria" was required; if the threshold was increased to "two B type criteria" about 10% met criteria for dual-diagnosis of a diagnosed general medical condition + Somatic Symptom Disorder.
For the 94 irritable bowel and chronic widespread pain study group, about 26% were coded when "one of the B type criteria" was required; 13% coded when "two B type criteria" was required.
7% of the healthy patient control group were also captured.
Despite the looseness of the proposed criteria set and its reliance on highly subjective and difficult to measure responses like "Disproportionate and persistent thoughts about the seriousness of one’s symptoms" and "Excessive time and energy devoted to these symptoms or health concerns", the SSD Work Group chose to take forward the criteria set option which required only "one of the B type criteria" to meet the diagnosis.

SSD and BDD license the application of an additional mental health diagnosis for all chronic illnesses – whether "established general medical conditions or disorders" like diabetes, heart disease and cancer, or conditions presenting with "somatic symptoms of unclear etiology" – if the clinician considers the patient is devoting too much time to their symptoms or that their life has become "subsumed" by health concerns and preoccupations, or their response to distressing, chronic, somatic symptoms is perceived as "excessive" or "disproportionate," or their coping strategies "maladaptive."
Furthermore, ICD-11 doesn't use rigid criteria sets like DSM-5 but disorder descriptions and characterizations which allow clinicians more flexibility to use their clinical judgement.
ICD-11's Bodily distress disorder is potentially more problematic than DSM-5's SSD.
