Concepts of Disease and Health

Ray Moynihan, B. Disease-mongering is a term to describe the process of widening the boundaries that define medical illness in order to expand markets for those who deliver and sell treatments. It can take many forms, including framing risk factors as diseases, portraying mild problems as severe pathology, widening existing definitions and constructing whole new categories of medical illness. While the analysis of disease-mongering has to date focussed largely on pharmaceutical marketing, and unhealthy industry-professional entanglement, the phenomenon is broader and deeper than a critique of drug company promotions. The concern is that by transforming more and more of the ups and downs of ordinary life into the signs and symptoms of treatable conditions, we may be producing much iatrogenic illness, wasting many resources and fundamentally shifting what it means to be human.

A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not due to any immediate external injury. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency , hypersensitivity , allergies and autoimmune disorders. In humans, disease is often used more broadly to refer to any condition that causes pain , dysfunction , distress , social problems , or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries , disabilities , disorders , syndromes , infections , isolated symptoms , deviant behaviors , and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories. Diseases can affect people not only physically, but also mentally, as contracting and living with a disease can alter the affected person's perspective on life. Death due to disease is called death by natural causes.

Disease and illness Distinctions between professional and popular ideas of sickness

Disease , any harmful deviation from the normal structural or functional state of an organism, generally associated with certain signs and symptoms and differing in nature from physical injury. A diseased organism commonly exhibits signs or symptoms indicative of its abnormal state. Thus, the normal condition of an organism must be understood in order to recognize the hallmarks of disease. Nevertheless, a sharp demarcation between disease and health is not always apparent. The study of disease is called pathology. It involves the determination of the cause etiology of the disease, the understanding of the mechanisms of its development pathogenesis , the structural changes associated with the disease process morphological changes , and the functional consequences of those changes. Correctly identifying the cause of a disease is necessary to identifying the proper course of treatment.


The dictionary defines “ill” in this third sense as “a disease, a sickness”. Looking up “sick- ness” we find “The condition of being sick or ill; illness, ill health”; and.


Health, disease and illness: matters for definition.

Health and disease are critical concepts in bioethics with far-reaching social and political implications. For instance, any attempt to educate physicians or regulate heath insurance must employ some standards that can be used to assess whether people are ill or not. Concepts of health and disease also connect in interesting ways with issues about function and explanation in philosophy of the biomedical sciences, and theories of well-being in ethics. Doctors are called on to deal with many states of affairs. Not all of them, on any theory, are diseases.

Illness and disease: an empirical-ethical viewpoint

The dysfunctional consequences of the Cartesian dichotomy have been enhanced by the power of biomedical technology. Technical virtuosity reifies the mechanical model and widens the gap between what patients seek and doctors provide. Illnesses are experiences of discontinuities in states of being and perceived role performances.

The point of departure for this article is a review of the discussion between Twaddle and Nordenfelt on the concepts of disease, illness, and sickness, and the objective is to investigate the fruitfulness of these concepts. It is argued that disease, illness, and sickness represent different perspectives on human ailment and that they can be applied to analyze both epistemic and normative challenges to modern medicine. In particular the analysis reveals epistemic and normative differences between the concepts.
