This document discusses medically unexplained physical symptoms (MUPS) and somatic symptom disorder. It defines MUPS as physical symptoms that exist without objective medical findings or explanations. Somatic symptom disorder is characterized by physical symptoms caused by psychological or emotional distress. The document reviews the epidemiology, risk factors, clinical features, diagnostic criteria, cultural influences, and approaches for evaluating and treating patients with somatic symptom disorder.

Physical Symptoms (MUPS)
Mohammed AlHinai

2. 24 yrs old college female student present with headache, fatigue, SOB and

is an estimated 5% to 7%, making this one of the most common
categories of patient concerns in the primary care setting.
• An estimated 20% to 25% of patients who present with acute somatic
symptoms go on to develop a chronic somatic illness.

13. Approach to patient with
somatic symptoms disorders

14. 24 yrs old college female student present with headache, fatigue, SOB and
dizziness for the last 3 days. She is not known to has any comorbidities.
How do you approach this
patient ?

15. History and examination
Taking a general medical history with a full review of systems, taking a psychiatric
history, performing a physical examination and a mental status examination
 History :
• History of presenting complaints.
• How these somatic symptoms affect his/her daily life?
• If there are Excessive thoughts, worrying, or behaviors (time and energy) related to the
somatic symptoms ?? (apply ICE).
• Past illness (focus on previous visits especially presenting complaints, result of tests,
diagnosis and treatment given) which could be taken by :
- From patient.
- From past medical record if available.
• Current medication.
• Family history of serious disease and psychiatric disorders.
• Social history to elicit the risk factors of somatic symptoms disorders.
• Screening for depression.
• Screening for somatic symptoms disorders.
 Physical examination :
• Based on presenting complaint.

16. Screening methods

18. When to suspect the disorder
• History of present illness is vague and inconsistent.
• Health care concerns are rarely alleviated despite high utilization of medical care –
Reassurance and explanation by clinicians.
• Multiple courses of standard treatment fail to mitigate the symptoms.
• Attributing normal physical sensations to medical illnesses.
• Seeking care from multiple doctors for the same somatic symptom(s).

19. Investigation
Criteria for selective use of tests include objective signs rather than the volume of
the concerns expressed by the patient, the presence of complex symptoms, and
persistence of symptoms.

20. Treatment
1- non-pharmacology therapy :

21. 2- Pharmacology therapy :
• For patients with treatment resistant somatic symptom disorder, plus prominent
symptoms of anxiety disorders, depressive disorders, or obsessive-compulsive
disorder.
• Start with low dose of :
- tri-cyclic anti-depressant include amitriptyline.
- SSRI
- SNRI
3- psychiatric referral :

 Provide explanation and reassurance by being told :
• The symptoms they have are common.
• Rarely associated with serious disease.
• these symptoms are real and their doctor is familial with them.
• Often settle with time.
• Need no be an impediment to an active life.
• Can be reviewed again when the symptoms persist.
 Discuss the treatment plan and agree follow up arrangement.

23. Prognosis
• Somatic symptoms disorders are generally chronic.
• Some studies shown that :
- 50% to 75% of patients with MUSD show improvement.
