This paper examines the concepts of health and disease as opposing ends of the wellness spectrum. Drawing on the World Health Organization's definition, it describes health as a state of complete physical, mental, and social well-being maintained through homeostasis. Disease is defined as a disruption of that equilibrium, characterized by identifiable signs, symptoms, and biological changes consistent with the biomedical model. The paper then reflects critically on potential biases embedded in these definitions, noting that an exclusive focus on biological factors may undervalue social, psychological, and environmental determinants of illness, and that defining health as "complete" well-being may set an unrealistically high standard for those living with chronic conditions.
The paper demonstrates critical self-reflection: after presenting definitions, the author turns the analytical lens on those definitions themselves. By noting that an emphasis on the biomedical model may overlook social and environmental factors, and that "complete well-being" sets an unrealistically high bar, the writer shows the ability to evaluate frameworks rather than simply accept them — a core skill in health sciences writing.
The paper is organized in three tight paragraphs. The first defines health using the WHO framework and introduces homeostasis as a unifying concept. The second defines disease through the biomedical lens, cataloguing causes and characteristics. The third critically evaluates both definitions, identifying gaps and advocating for a more integrated approach. This straightforward define-then-critique structure is well-suited to short reflective essays in medicine and public health courses.
Health and disease are two concepts in medicine and human biology that represent opposite ends of the wellness spectrum. My definition of health aligns with that of the World Health Organization, which describes health as the absence of disease and as a state of complete physical, mental, and social well-being. This holistic view suggests that health is more than just the status of the physical body; it includes psychological and social dimensions as well (Kalariya et al., 2023). Health, in this sense, is an ever-changing state of equilibrium — or homeostasis — in which the body's systems function optimally within a constantly changing environment.
Disease can be defined as a disruption or imbalance in this state of homeostasis, characterized by identifiable signs and symptoms. It is a condition that impairs normal functioning and is typically associated with specific causes and observable physical or biochemical changes. Diseases can be acute or chronic, and they may be caused by external factors such as pathogens or by internal dysfunctions such as autoimmune disorders. This definition aligns with the biomedical model, which views disease primarily in terms of biological factors (Longino, 2020).
