Difficulty: EasySomatic Symptom and Eating Disorders

A 2828-year-old graphic designer is evaluated at an outpatient clinic following a referral from her gastroenterologist. For the past 1414 months, she has experienced persistent, daily pelvic discomfort and generalized muscle aches. She describes these sensations as severely distressing and states that they significantly impair her ability to focus on her job. She spends roughly 33 to 44 hours each evening researching her physical symptoms on medical forums, firmly believing she suffers from an undetected, rare autoimmune pathology. Extensive laboratory tests, pelvic ultrasounds, and endoscopic evaluations have repeatedly shown no organic abnormalities. She does not intentionally produce or feign these symptoms. Which of the following is the most likely diagnosis?

  1. Somatic symptom disorderAnswer
  2. B
    Illness anxiety disorder
  3. C
    Factitious disorder
  4. D
    Conversion disorder
  5. E
    Malingering

Answer

Somatic symptom disorder
The correct answer is Somatic symptom disorder because the patient presents with one or more somatic symptoms (pelvic discomfort, muscle aches) that are highly distressing and disrupt daily life. Furthermore, she exhibits excessive behaviors and thoughts related to these symptoms (spending hours researching, believing she has a rare illness) that have persisted for more than 6 months. Her symptoms are not intentionally feigned, confirming a true somatic spectrum pathology.

Step-by-Step Solution

1
Identify the patient's primary symptoms and their duration.
The patient has actual physical symptoms (pelvic discomfort, muscle aches) that are severely distressing and have lasted for over a year (14 months).
Establishing the presence and duration of physical symptoms is the first step in diagnosing somatic symptom and related disorders.
2
Evaluate the patient's psychological response to the symptoms.
The patient exhibits excessive thoughts and behaviors related to her health, spending 3 to 4 hours daily researching her symptoms and believing she has a severe, undetected illness despite negative workups.
DSM-5 criteria for somatic symptom disorder require excessive thoughts, feelings, or behaviors related to the somatic symptoms.
3
Rule out intentional production of symptoms and alternate specific diagnostic categories.
The symptoms are not intentionally produced (ruling out factitious disorder and malingering), and there are no specific neurological motor/sensory deficits (ruling out conversion disorder). Furthermore, the physical symptoms are prominent and distressing, ruling out illness anxiety disorder.
Accurate psychiatric diagnosis requires confirming the condition is not better explained by a differential diagnosis on the somatic spectrum.

Key Concept

The primary distinction between Somatic Symptom Disorder and Illness Anxiety Disorder is the prominent presence of distressing physical symptoms in the former.
