Somatic symptom disorder and illness anxiety disorder are concerned with medical illness, yet they are different. Explain using relevant example.
Somatic symptom disorder and illness anxiety disorder are concerned with medical illness, yet they are different. Explain using relevant example.
Both disorders involve excessive concern about health, but they differ in whether actual physical symptoms are present.
Somatic Symptom Disorder (SSD):
- Real, distressing physical symptoms (e.g., chronic pain, fatigue) are present.
- The person has excessive thoughts, feelings, or behaviours related to these symptoms that disrupt daily life.
- Example: Ramesh has unexplained chronic back pain and repeatedly visits doctors, unable to function normally because of his preoccupation with it.
Illness Anxiety Disorder (IAD):
- Little or no actual physical symptoms exist.
- The person is intensely anxious about having or acquiring a serious illness and constantly checks their body or avoids doctors.
- Example: Sita has no real symptoms but is convinced she has heart disease and repeatedly checks her pulse out of fear.
Marking Scheme
- 11 mark: correct explanation of Somatic Symptom Disorder with a suitable example.
- 21 mark: correct explanation of Illness Anxiety Disorder with a suitable example, bringing out the key difference (presence vs absence of actual physical symptoms).
Hint
SSD = real symptoms + excessive worry about them; IAD = little/no symptoms + intense fear of having an illness.
Quick Oral Answer
SSD is marked by real distressing physical symptoms with excessive anxious thoughts about them, while illness anxiety disorder involves intense fear of having a serious illness despite few or no actual physical symptoms.
Analysis & Explanation
This question tests the key distinguishing feature within somatoform-spectrum disorders introduced in DSM-5.
Concept:
DSM-5 split the older category of 'hypochondriasis' into two disorders based on whether significant somatic symptoms are actually present. SSD is defined by the presence of one or more distressing somatic symptoms plus excessive health-related thoughts, feelings, or behaviours devoted to them. IAD, in contrast, is defined by high anxiety about having a serious illness with minimal or absent somatic symptoms — the anxiety itself, not the symptom, is the central problem.
Exam trap:
Students often treat the two as synonyms of 'health worry' and fail to state the core differentiator — presence versus absence of significant bodily symptoms. A 2-mark answer must explicitly state this difference and support it with one example each.
Real-world relevance:
Both conditions cause real functional impairment and are treated through cognitive-behavioural approaches; distinguishing them helps clinicians choose whether treatment should target symptom-coping (SSD) or health-anxiety reduction (IAD).
Common Mistakes
- 1Treating both disorders as identical/synonymous instead of highlighting that SSD involves real bodily symptoms while IAD involves anxiety with minimal or no actual symptoms.
- 2Giving definitions without a concrete example, which loses marks in a 2-mark 'explain with example' question.
Interesting Facts
Illness anxiety disorder was earlier called 'hypochondriasis' in DSM-IV; DSM-5 split it into illness anxiety disorder and somatic symptom disorder based on presence of somatic symptoms.
Studies show a large proportion of people with illness anxiety disorder also have another co-occurring anxiety or depressive disorder.
People with SSD often visit multiple doctors ('doctor shopping') because reassurance from any one doctor provides only temporary relief.

Frequently Asked Questions
Is illness anxiety disorder the same as hypochondriasis?
Yes, illness anxiety disorder is the term that replaced hypochondriasis in DSM-5, referring to excessive worry about having a serious illness with minimal or no actual somatic symptoms.
Can a person have both SSD and IAD together?
It is uncommon but possible to show overlapping features; however, DSM-5 classifies a person primarily under SSD if significant somatic symptoms are present, and under IAD if anxiety exists with little or no actual symptoms.
