Disorders of bodily distress or bodily experience are characterized by disturbances in the person’s 
experience of their body. Bodily distress disorder involves bodily symptoms that the individual 
finds distressing, and to which excessive attention is directed. Body integrity dysphoria involves 
a disturbance in the person’s experience of the body manifested in the persistent desire to 
have a specific physical disability, accompanied by persistent discomfort or intense feelings of 
inappropriateness concerning current non-disabled body configuration.
Bodily distress disorder
Essential (required) features
• The presence of bodily symptoms that are distressing to the individual is required for 
diagnosis. Typically, this involves multiple bodily symptoms that may vary over time. 
Occasionally, the focus is limited to a single symptom – usually pain or fatigue.

Disorders of bodily distress or bodily experience include the following:

Clinical Descriptions and Diagnostic Requirements for ICD-11 Mental, Behavioural or Neurodevelopmental Disorders
• Excessive attention is directed towards the symptoms, which may manifest in:
• persistent preoccupation with the severity of the symptoms or their negative 
consequences – in individuals who have an established medical condition that may be 
causing or contributing to the symptoms, a degree of attention related to the symptoms 
that is clearly excessive in relation to the nature and severity of the medical condition;
• repeated contacts with health-care providers related to the bodily symptoms that are 
substantially in excess of what would be considered medically necessary.
• Excessive attention to the bodily symptoms persists, despite appropriate clinical 
examination and investigations or appropriate reassurance from health-care providers.
• Bodily symptoms are persistent; that is, some symptoms are present (although not 
necessarily the same symptoms) on most days during a period of at least several months 
(e.g. 3 months or more).
• The bodily symptoms and related distress and preoccupation result in significant 
impairment in personal, family, social, educational, occupational or other important areas 
of functioning.
• The symptoms or the associated distress and preoccupation are not better accounted for 
by another mental disorder (e.g. schizophrenia or another primary psychotic disorder, a 
mood disorder, or an anxiety or fear-related disorder).
Severity of bodily distress disorder
The severity of bodily distress disorder should be classified based on the degree of distress 
or preoccupation with bodily symptoms, the persistence of the disorder and the degree of 
impairment. The clinician should make a global determination of the appropriate rating 
of severity based on the overall clinical presentation, and select one of the following 
subcategories.
Mild bodily distress disorder
• All the essential features of bodily distress disorder are present.
• Although there is excessive attention to distressing symptoms and their consequences, 
which may result in frequent medical visits, the individual spends only a limited amount 
of time focusing on them (e.g. no more than 1 or 2 hours per day), and is able to focus on 
other unrelated topics.
• The bodily symptoms and related distress and preoccupation result in mild impairment in 
personal, family, social, educational, occupational or other important areas of functioning 
(e.g. strain in relationships, less effective academic or occupational functioning, 
abandonment of specific leisure activities).
Moderate bodily distress disorder
• All the essential features of bodily distress disorder are present.
• Persistent preoccupation with the distressing symptoms and their consequences is typically

associated with frequent medical visits. The individual devotes a substantial amount of 
time and energy to focusing on the symptoms and their consequences (e.g. several hours 
per day).
• The bodily symptoms and related distress and preoccupation result in moderate 
impairment in personal, family, social, educational, occupational or other important areas 
of functioning (e.g. relationship conflict, performance problems at work, abandonment of 
a range of social and leisure activities).
Severe bodily distress disorder
• All the essential features of bodily distress disorder are present.
• The presentation is characterized by a pervasive and persistent preoccupation with the 
distressing symptoms and their consequences, and a narrowing of interests such that 
the bodily symptoms and their consequences become the nearly exclusive focus of the 
individual’s life, typically resulting in extensive interactions with the health-care system.
• The bodily symptoms and related distress and preoccupation result in severe impairment in 
personal, family, social, educational, occupational or other important areas of functioning 
(e.g. unable to work, alienation of friends and family, abandonment of nearly all social and 
leisure activities).
Bodily distress disorder, unspecified
Additional clinical features
• The most common bodily symptoms associated with bodily distress disorder include 
pain (e.g. musculoskeletal pain, backache, headaches), fatigue, and gastrointestinal and 
respiratory symptoms, although patients may be preoccupied with any bodily symptoms. 
The individual can generally provide a detailed description of the symptoms, but it may be 
difficult for clinicians to account for the symptoms in anatomical or physiological terms.
• Individuals with bodily distress disorder often over-interpret or catastrophize about their 
bodily symptoms, and dwell on their most extreme negative consequences. For example, 
in more severe cases, pain or fatigue may be perceived as being so intense that they prevent 
normal activities, despite there being no medical basis for such a belief. This is often 
accompanied by fear of triggering pain or an exacerbation of other symptoms, which may 
lead to undue avoidance of activities; this may in turn lead to other symptoms associated 
with inactivity (e.g. stiffness and muscle weakness, muscle pain following minimal 
exertion).
• Individuals with bodily distress disorder may hold a range of attributions regarding their 
symptoms, including psychological and physical explanations. As severity increases, 
affected individuals are more likely to reject psychological explanations for their symptoms. 
Some individuals with bodily distress disorder believe that their bodily symptoms indicate 
underlying physical illness or injury (i.e. disease conviction), even though this has not 
been detected. Insistence that the symptoms are caused by an undiagnosed illness or

injury may result in multiple medical tests and procedures. This pattern is most common 
in individuals with severe bodily distress disorder, who may have long and complicated 
histories of contact with both primary and specialist medical services, during which many 
negative investigations or fruitless operations across various body systems may have been 
carried out.
• Individuals with bodily distress disorder most often present in general medical settings 
rather than for mental health services. They may be reluctant to agree that there is a 
psychological component to their experience, and may react negatively to the suggestion 
of a referral to a mental health professional.
• Individuals with bodily distress disorder often express dissatisfaction with the medical 
care they have received previously, and may change health-care providers frequently.
• In communities with limited access to health care, individuals with bodily distress disorder 
may not have extensive interactions with the formal health-care system, but they may seek 
care from alternative sources.
• Bodily distress disorder often occurs in the context of comorbid medical conditions and 
co-occurring mental disorders – especially depressive disorders and anxiety and fearrelated disorders.
Boundary with normality (threshold)
• The experience of bodily symptoms and occasional concern about them is normal. However, 
people with bodily distress disorder report greater distress about their bodily symptoms 
than would generally be regarded as proportional to the nature of the symptoms, and their 
excessive attention to their symptoms is not alleviated by appropriate clinical examination 
and investigations, and by reassurance from health-care providers.
• Individuals with bodily distress disorder who have a comorbid medical condition that 
may be causing or contributing to the bodily symptoms exhibit greater preoccupation with 
symptoms and greater functional impairment than those who have a medical condition that 
is similar in nature and severity without concurrent bodily distress disorder. Furthermore, 
the number of bodily symptoms reported often exceeds that usually associated with the 
comorbid medical condition.
Course features
• In about half of individuals diagnosed with bodily distress disorder seen in primary care 
settings, bodily symptoms resolve within 6–12 months. Individuals with severe disorder 
and those with multiple bodily symptoms tend to experience a more chronic and persistent 
course. The presence of multiple bodily symptoms is commonly associated with greater 
impairment in functioning, as well as with poorer treatment response for any co-occurring 
mental or medical conditions.

Developmental presentations
• Bodily distress disorder can occur across the lifespan. The most common bodily symptoms 
in children and adolescents include recurrent gastrointestinal symptoms (e.g. abdominal 
pain, nausea), fatigue, headaches and musculoskeletal pain. Children are more likely to 
experience a single recurrent symptom rather than multiple bodily symptoms. School 
absences due to symptoms are common. In severe cases, children may display regression 
of behaviour and extreme impairment – for example, affecting self-care and mobility.
• In children and adolescents, parental or caregiver responses to symptoms can affect the 
course and severity of bodily distress disorder, as well as whether medical attention is 
sought. For example, excessive parental or caregiver concern can worsen the severity or 
prolong the course of the disorder in children.
• Older adults with bodily distress disorder are more likely than younger adults with 
the condition to have multiple bodily symptoms, and symptoms are more likely to be 
persistent. The diagnosis of bodily distress disorder in older adults can be challenging due 
to the higher likelihood of medical conditions that may account for symptoms, or that are 
comorbid with bodily distress disorder.
Culture-related features
• Somatic symptoms are common in all cultural groups, especially among people seeking 
health care. Differences in rates of bodily symptoms may be related to cultural reporting 
styles. Differences may also reflect the organizational culture of the health-care system, 
with somatic complaints more likely where clinical encounters are brief and the delivery of 
services is less person-centred.
• Symptoms that are common in one cultural group may be less common in other groups. 
For example, whereas pain symptoms are common across cultures, symptoms such as 
heat in the body or in the head, crawling sensations, heaviness, or complaints of “gas” or 
abdominal bloating are common in certain cultural group but not in others.
• Culture may influence explanatory models, with symptoms variously attributed to forms 
of bodily energy, humours or other ethno-physiological concepts, as well as religious, 
spiritual, personal, family or environmental stresses. Some specific attributions, such as 
symptoms being caused by semen loss or kidney weakness, are common in certain cultural 
group but not in others.
• Across cultural groups, people with multiple distressing bodily symptoms are likely to seek 
health care, including from traditional or faith healers. However, help-seeking behaviour 
is also substantially influenced by access to health-care services. Individuals may not have 
extensive interactions with the formal health-care system because of limited opportunities 
to access health care, which varies substantially by cultural group.

Sex- and/or gender-related features
• Prevalence rates do not appear to differ by gender prior to puberty, after which prevalence 
is higher in females.
• Symptom presentation may vary by gender, with women more likely to report multiple 
bodily concerns.
Boundaries with other disorders and conditions (differential diagnosis)
Boundary with mood disorders
Among individuals with mood disorders, somatic symptoms may be the dominant aspects of 
the clinical presentation – particularly in primary care settings. In addition, some individuals 
with mood disorders may develop neurovegetative symptoms (e.g. weight loss, fatigue) or other 
associated physical symptoms (e.g. pain), about which they become preoccupied. Bodily distress 
disorder should be diagnosed only if the preoccupation with physical symptoms occurs outside 
the context of mood episodes – for example, if the preoccupation precedes a depressive episode 
or persists after the depressive episode has remitted.
Boundary with generalized anxiety disorder
Individuals with generalized anxiety disorder may report somatic symptoms about which they 
are concerned (e.g. palpitations or gastric distress), but they also report concerns about negative 
events occurring in several different aspects of everyday life (e.g. work, relationships, finance). 
Unlike individuals with bodily distress disorder, individuals with generalized anxiety disorder 
do not typically exhibit a preoccupation with bodily symptoms that persists despite medical 
evaluation and reassurance. However, co-occurrence of bodily distress disorder and anxiety and 
fear-related disorders is common, although individuals with bodily distress disorder are less likely 
to endorse the psychological components of anxiety other than distress about their bothersome 
symptoms.
Boundary with panic disorder
Panic disorder is characterized by recurrent, unexpected, self-limited episodes of intense fear 
or apprehension with prominent somatic symptoms and feelings of an impending catastrophe 
(e.g. fainting, having a stroke, heart attack or dying), with a sense of immediacy of the threat. 
Individuals with panic disorder often become preoccupied with the transient somatic symptoms 
they experience during panic attacks, and may express concern that they are dangerous and 
suggestive of imminent harm. An additional diagnosis of bodily distress disorder should not be 
assigned on the basis of concern about symptoms experienced during panic attacks. However, if 
individuals with panic disorder are excessively attentive to or preoccupied by persistent somatic 
symptoms that are distinct from those typically associated with panic attacks, and all diagnostic 
requirements for both disorders are met, both diagnoses may be assigned.
