Somatic Symptom Disorder

Somatic Symptom Disorder involves one or more physical symptoms that are distressing or significantly disrupt daily life, accompanied by excessive thoughts, feelings, or behaviors related to those symptoms — such as persistent, high anxiety about their seriousness, or disproportionate time and energy devoted to health concerns. Importantly, the diagnosis does not require symptoms to be medically unexplained: a person can have a genuine medical condition alongside a disproportionate psychological response to it.

Somatic Symptom Disorder is defined by one or more somatic symptoms that are distressing or disrupt daily life, together with excessive thoughts, feelings, or behaviors related to the symptoms or associated health concerns — evidenced by disproportionate and persistent thoughts about their seriousness, persistently high health-related anxiety, or excessive time and energy devoted to symptoms or health concerns. Although any single symptom may not be continuously present, the symptomatic state itself is typically persistent, usually more than six months.

Somatic Symptom Disorder reflects a genetic vulnerability toward heightened bodily awareness and anxiety, often shaped by childhood experiences of illness — one's own or a family member's — that influence how bodily sensations are later interpreted. A tendency toward heightened interoceptive sensitivity (increased awareness of and attention to internal bodily sensations) is central, and co-occurring anxiety or depression can amplify the perceived intensity or threat of physical symptoms.

• Family history of somatic symptom disorder or significant childhood illness exposure
• Co-occurring anxiety or depressive disorders
• History of trauma or significant adverse childhood experiences
• Female sex
• Chronic medical conditions, which can co-occur alongside a disproportionate psychological response
• Personality traits involving heightened anxiety sensitivity

Heightened activity in brain regions involved in interoceptive processing and threat appraisal — including the insula and anterior cingulate cortex — is implicated, causing normal bodily sensations to be perceived as more intense, threatening, or significant than they objectively are. This reflects a genuine difference in how the brain processes and interprets bodily signals, not a conscious choice to exaggerate symptoms.

• One or more persistent physical symptoms — pain, fatigue, gastrointestinal complaints, or others — causing distress or functional impairment
• Disproportionate and persistent worry about the seriousness of the symptoms
• High health-related anxiety
• Excessive time and energy spent on symptoms or health concerns — frequent doctor visits, extensive symptom research, repeated self-checking
• Symptoms persisting for 6 months or more, even if the specific symptom varies over time

• One or more distressing or disruptive somatic symptoms
• Excessive health-related thoughts, feelings, or behaviors, evidenced by 1+ of: disproportionate concern about seriousness, high health anxiety, or excessive time/energy devoted to symptoms
• A persistently symptomatic state, typically over 6+ months

Conditions a psychiatrist will consider and rule out before confirming this diagnosis:

Illness Anxiety Disorder

Health anxiety is present with minimal or no actual somatic symptoms — the worry itself, rather than the symptom burden, is the primary feature.

Genuine, undiagnosed medical conditions

Should always be appropriately investigated and ruled out or identified, since a real medical condition can coexist alongside a disproportionate psychological response.

Panic Disorder

Physical symptoms occur specifically during discrete panic episodes rather than as a persistent pattern.

Factitious Disorder

Symptoms are intentionally produced or feigned, unlike the genuine subjective distress in Somatic Symptom Disorder.

• Thorough medical history and physical examination to appropriately evaluate reported symptoms, while avoiding excessive, repeated testing that can reinforce health anxiety
• Collaboration between psychiatry and the treating medical team
• Screening for co-occurring anxiety or depression
• Review of the pattern and history of healthcare-seeking behavior

A collaborative approach between psychiatry and primary or specialist medical care is important, ideally with a single, consistent point of medical contact to avoid fragmented or excessive testing. Psychotherapy, particularly CBT, is the primary evidence-based treatment, and medication may help with co-occurring anxiety or depression.

SSRIs/SNRIs

May help reduce symptom-focused anxiety and treat co-occurring depression or anxiety, though no medication treats the core disorder directly.

Cognitive Behavioral Therapy

Addresses catastrophic thinking about symptoms and excessive health-related behaviors.

Mindfulness-based approaches

Can help reduce the intensity of focus on bodily sensations.

Consultation-liaison psychiatry

Working alongside the primary treating physician to provide consistent, coordinated care.

• Maintain regular contact with a single, trusted primary care physician rather than seeking multiple opinions repeatedly
• Engage in regular physical activity as tolerated
• Practice stress management and relaxation techniques
• Limit excessive symptom-checking behaviors, such as repeated online searching
• Maintain social and occupational engagement despite symptoms where possible

With appropriate psychotherapy and a consistent, coordinated medical relationship, many people experience meaningful reduction in distress and improved functioning, even if some physical symptoms persist. The condition can become chronic without treatment, and is associated with significant healthcare utilization and functional impact if unaddressed.

• Early, appropriate medical evaluation and reassurance for health concerns, avoiding both dismissal and excessive repeated testing
• Addressing childhood illness-related anxiety and modeling healthy illness behavior within families
• Early treatment of co-occurring anxiety or depression

Take the person's distress seriously — the symptoms and worry are genuinely experienced, not fabricated or dismissively 'all in their head.' Avoid reinforcing excessive health-related behaviors, such as constant reassurance-seeking or repeated symptom-checking, while still providing appropriate support. Encourage engagement with a single, consistent healthcare provider rather than doctor-shopping, and support psychotherapy engagement as a genuine, evidence-based treatment.
