In one sentence Disease is what the clinician can find in the body, illness is what the person lives through, and sickness is the social position that others grant to the unwell.
Disease, illness and sickness are three different things
Medical training teaches one word — disease — for a biological process: an infection, a lesion, a failing organ. The patient lives something else: pain, fear, fatigue, changed plans, changed relationships. Sociology separates the three levels so that each can be examined. Disease is the organic process; illness is the personal experience of it; sickness is the social role and the expectations attached to being unwell. The three do not move together. A person with a positive test may feel entirely well and still be treated as sick; a person in severe pain with no visible abnormality may be treated as well and left alone. Confusing the levels is the source of most misunderstanding between patients and staff, and of most misplaced blame.
A man whose leg ulcer has healed returns to work still feeling ill; his employer sees a healed wound and refuses him light duties. The disease has gone, the illness and the social role have not.
A patient’s X-ray is normal but she says she can no longer work. Is she ill?
Show the answer
Yes, in the sense of illness. The radiograph reports disease, not experience: nothing in a normal image contradicts pain, fatigue or fear. The nursing task is to assess the lived experience and ask what has changed in her life, not to declare the problem unreal because the image is clean.

- Idioms of distress and somatisation: how the body carries the message
The medical anthropologist Mark Nichter introduced the term idiom of distress in 1981, working on healing in South Asia, to name a socially and culturally resonant way of expressing distress. Two features of his definition do the work. First, an idiom is learned and shared: it is intelligible to others, so it can be answered. Second, it is preferred rather than merely available — out of all the ways a person might signal suffering, this is the one the community recognises as a legitimate call for help, and the one that will be met with concern rather than contempt. A complaint such as “thinking too much”, “the heart is heavy” or “ants are walking in my head” is therefore not a poor translation of a psychiatric symptom; it is the accepted local grammar of distress, and it usually carries a social situation with it — a lost job, a co-wife conflict, a debt, a bereavement. Arthur Kleinman and colleagues argued in the same period that somatisation should be read as a communication process rather than as a residual category of illness with no cause. Laurence Kirmayer later made the decisive clinical distinction: somatisation as a symptom is a phenomenon that may need treatment, whereas somatisation as an idiom is a means of communication that may be adaptive, protecting the person from a stigma that an emotional label would attract. The empirical anchor predates the theory. In 1952 Mark Zborowski compared patients in a New York hospital and found systematic differences between groups in what they reported about pain and in the comfort they wanted, although the underlying conditions were comparable: the sensation was not what varied, the expression and the expected response were. Nursing application follows directly. When investigation is normal, do not close the case; translate. Use the patient’s own word for the complaint, state plainly that you believe the symptom, name the limit of the test (“this does not explain the burning”), and ask what has been happening in the patient’s life since it began. At the same time, do not use the idiom idea as a reason to stop investigating: where access to care is scarce, a somatised presentation may accompany real tuberculosis, HIV or anaemia. Investigate and translate; refuse to choose between the two.
- Stigma as a social process: labelling, power and its consequences
Goffman’s 1963 essay is more precise than the word “stigma” usually suggests. He distinguished three broad kinds of stigmatised attribute: abominations of the body, such as a visible deformity or a healed burn; blemishes of individual character, inferred from mental illness, epilepsy, HIV, addiction or imprisonment; and tribal stigma of race, nation or religion, which is applied to a whole lineage. He also separated the discredited, whose mark is already visible and who must manage tension in every encounter, from the discreditable, whose mark is hidden and who must manage information — passing as ordinary, covering the trait when passing is impossible, or disclosing selectively to a few trusted people. Family members carry what he called courtesy stigma, and he noted the role of the “wise”: people who are not marked themselves but are accepted by the stigmatised because they treat them as ordinary.
The labelling tradition, associated with Howard Becker, explains how the mark gets attached. Becker’s Outsiders argued that deviance is not a quality of the act but a consequence of the application of rules and sanctions by others; Edwin Lemert had already distinguished primary deviance, the original act, from secondary deviance, the reorganisation of a person’s identity around the label and the reaction to it. Bruce Link’s modified labelling theory added the psychological mechanism: once labelled, people expect rejection, and that expectation produces withdrawal, secrecy and reduced help-seeking even before anyone rejects them.
Link and Phelan then specified when stigma actually exists, and the specification is the most useful part for nursing. Stigma requires that differences be labelled; that labels be linked to negative stereotypes; that labelled people be separated into a “them”; that this produce status loss and discrimination; and that all of it depend on access to social, economic and political power. The power condition explains why the same symptom is trivial in a consultant and fatal to a marriage prospect in a village. Graham Scambler’s distinction between enacted stigma — actual discrimination — and felt or anticipated stigma — the fear of it — completes the picture, because felt stigma often does the greater damage: it works preventively, keeping people away from clinics, tests, antenatal care and treatment, so the harm occurs before any act of discrimination does.
In nursing the consequences are concrete: delayed diagnosis in tuberculosis and HIV, hidden medication, missed appointments, poor adherence, lost employment, and the refusal of families to allow contact tracing. Countermeasures therefore have to be social, not merely kind. Confidential files and careful wording in shared documents, private spaces for counselling, universal precautions applied to everyone, contact tracing designed so that the patient is not visibly singled out, peer groups of people living with the condition, and a named person prepared to challenge discrimination inside the service all reduce enacted and anticipated stigma at once.
- Biographical disruption, loss of self and narrative reconstruction
Bury’s 1982 paper on chronic illness as biographical disruption rested on interviews with people living with rheumatoid arthritis, and its argument is structural rather than emotional. He claimed that chronic illness disrupts three things at once. The first is the taken-for-granted knowledge of the body — the unexamined certainty about what one’s body can normally do and where its limits lie. The second is the assumed trajectory of the life course: the sense that plans already made will be kept and that the future will resemble the past. The third is the availability of resources and relationships with which to face the trouble. He also described the work patients then do, which he called the mobilisation of resources: reorganising time, delegating tasks, drawing on kin and savings, and revising what they will now attempt.
Gareth Williams took the analysis further in 1984 by studying people with arthritis and naming narrative reconstruction: the labour of repairing implicit theories of the self and the world through the language of a story — “why me, why now, and what does this mean for who I am?” The person is not merely describing events but restoring a connection between body, self and society. Kathy Charmaz added the concept of loss of self under conditions of intrusive illness: when the illness takes over daily life, the valued identities a person held — worker, parent, host, elder — lose their audience, and the self becomes a burden to be managed and, sometimes, hidden.
Arthur Frank’s The Wounded Storyteller described the three narrative shapes that illness stories usually take. The restitution narrative says, in effect, “I was well, I am ill, I will be well again”, and it fits medicine’s own plot. The chaos narrative has no sequence and no distance from the suffering, and it is the hardest to listen to because it refuses to become a tidy story. The quest narrative treats the illness as a journey that yields something — knowledge, a changed purpose, a new community.
The limit of the disruption idea matters as much as the idea. Faircloth and colleagues, interviewing stroke survivors in 2004, found not rupture but biographical flow: for many people the illness was folded into a life already marked by earlier hardship, and it confirmed rather than broke the story they were living. Whether an illness disrupts or merely continues a biography depends on the condition and its visibility, the person’s age and stage of life, the presence of supportive relationships, and the meanings available in the community. This is what makes disruption a question to ask rather than an assumption to apply. The nursing application is narrative competence rather than psychotherapy: invite the story rather than conducting an interrogation, ask what has changed and what the person believes has been lost, write the “before” into the record alongside the clinical findings, notice which narrative shape you are hearing, and never rush a chaos narrative into a restitution one. Then convert the story into practical action — a driving licence review, adapted duties, a school deferral, a peer group, a person to accompany the patient to the next appointment.
