Physiologically explainable symptoms
"Physical symptoms which are not caused by physical disease or injury are very common, and can become very distressing and disabling. They can be caused by over-use (e.g. ‘cramp’ or tiredness) or over-breathing (e.g. ‘pins and needles’ or giddiness) but are usually explained by natural physiological processes.
1 They are often explainable by reference to very well established physiological explanations of stress on the body, e.g. lactate build-up in muscles with over-use or acid-base imbalances from hyperventilation causing giddiness or tingling. They can be a result of an interaction between the physical trigger for the symptoms (e.g. a virus or an acute injury) and an individual’s cognitive, behavioural and emotional responses which may perpetuate these symptoms. Many patients with these symptoms meet criteria for a recognised syndrome such as chronic fatigue syndrome, irritable bowel syndrome, non-cardiac chest pain and fibromyalgia. They can also be a result of anxiety or depression which needs treatment in its own right.
Describing these symptoms as medically unexplained is incorrect, confusing and even frightening to those experiencing and not understanding them – more empowering, recovery-focused approaches are evidence-based.
Why specific symptoms occur may be explained by the context and prior experience of the person concerned – so may have psychological significance e.g. the interpretation of chest pain as due to a heart attack when a close relative has recently died of this. Persistent and more severe symptoms – often referred to as somatoform disorders – can benefit from intervention, e.g. cognitive behaviour therapy or graded exercise therapy, and even more complex ones from liaison services."

What is the problem?
Physical symptoms which are not caused by physical disease or injury are extremely common with many people experiencing them most days (e.g. headache, cramp, tiredness) but not normally requiring medical intervention. However quite commonly, people present and re-present to primary care or emergency departments because of concern that these physical symptoms may be caused by a physical disease.
19 per cent of new primary care GP appointments, especially frequent attenders, were found to be for people whose symptoms were previously described as ‘medically unexplained symptoms’ (MUS) but may be better described as physiologically explainable symptoms (PES)
2-3.
In secondary care (physical health trusts/services), a number of studies in both the UK and the United States have shown that up to 50 per cent of sequential new attenders at outpatient services have PES (‘MUS’). For example, percentage with PES (‘MUS’) in new attenders at the outpatient department, King’s College Hospital, London
4 by specialty were found to be:
- Chest (59%)
- Cardiology (56%)
- Gastroenterology (60%)
- Rheumatology (58%)
- Neurology (55%)
- Gynaecology (57%)
- Dental (49%)
Analysis of 2008/2009 NHS figures shows that people with these problems account for as many as:
- one in five new consultations in primary care,
- 7 per cent of all prescriptions,
- 25 per cent of outpatient care,
- 8 per cent of inpatient bed days, often repeat admissions, and
- 5 per cent of A&E attendances,
Women are three to four times more likely to experience PES (‘MUS’) than men.

What do service users and carers want?
Management of physical symptoms which are not due to physical disease or injury can be complex but patients and carers consistently say that they want information (
www.rcpsych.ac.uk/mentalhealthinfo/improvingphysicalandmh.aspx), explanation and good services

What works?
Primary care interventions focus on the consultation style adopted by professionals rather than defined psychological interventions (summarised in Improving Access to Psychological Therapies (IAPT) guidance
7 and the recent Forum for Mental Health in Primary Care guidelines
8.
Symptom reattribution has been found to be a successful form of intervention for people with PES (‘MUS’). This is a structured consultation delivered by GPs which provides a psychological explanation to patients with somatised disorder
9. However, while it does improve doctor-patient communication, it may not improve patient outcomes
10.
Identification and management of symptoms and treatment of any associated symptoms of depression or anxiety in accordance with the relevant National Institute for Health and Clinical Excellence (NICE) guidelines can be beneficial to those disorders. However, successful psychological treatment is usually dependent on treatment models specific to the PES (‘MUS’) delivered by therapists with training in this area.
Specialist services where persistent symptoms present are more successful where they focus on specific syndromes, e.g. chronic fatigue syndrome or irritable bowel syndrome.
Liaison teams provide multidisciplinary care for patients presenting with more complex PES (‘MUS’) including associated high levels of disability and high levels of distress
11.
Pain, fatigue or more generic clinics, e.g. rheumatology or G-I, may have psychological intervention integrated within them; this collaborative model may be more acceptable to patients presenting and improve identification and management
A meta-analysis of treatment for chronic fatigue syndrome suggests that both CBT and graded exercise therapy are promising treatments, with CBT possibly the more effective treatment in patients who have co-morbid anxiety and depressive symptoms
12.
Psychological treatments are effective for irritable bowel syndrome (including CBT and psychotherapy, either alone or in conjunction with antidepressant medications)
13, fibromyalgia,
14 and multisomatoform disorder (brief psychodynamic psychotherapy)
15.
Positive outcomes depend on:
- Provision of empowering ‘normalising’ physiological explanations of symptoms in primary, community and secondary care16.
- Where symptoms persist, offering prompt intervention using ‘low intensity’ or ‘high intensity’ psychological interventions based on a clear biopsychosocial understanding and formulation of these conditions
- Availability of specialist services (e.g. fatigue or pain services) or psychiatric liaison teams for further care especially where physical illness complicates, restoration of function has not occurred or where substantial acute service resources being used.

What information is there on cost?
Estimated cost to the NHS associated with PES (‘MUS’) of £3.1 billion
17. However, about half the cost (£1.2 billion) was spent on the inpatient care of less than 10 per cent of people with PES (‘MUS’) – a relatively small number of people receive very expensive and inappropriate care.
While the economic case for CBT is most compelling if resources are targeted at those with full somatoform disorders, the case for also tackling sub-threshold conditions is strong. All models are likely to be cost saving in the long-term.
Cost models rely on evidence of effectiveness from studies in the United States, which may not be easily generalizable to an English context. However, sensitivity and threshold analyses indicate that, even assuming very limited improvements in health outcomes, investing in actions to tackle somatoform disorders remains cost-effective from a societal perspective under most scenarios.
Pathways can be developed for ‘functional/MUS/physiological explainable symptoms’ with evidence for cost savings being greatest at the severe end using collaborative care.
More information is required on the relative effectiveness of e-learning compared to face-to-face learning as a way of raising GP awareness, because costs are substantially lower.
