Disease & Illness

Disease and illness are terms often used interchangeably in everyday language, but they have distinct meanings in medical contexts.

A disease refers to a specific pathological condition of a bodily part, an organ or system resulting from various causes such as infection, genetic defect, or environmental factors, characterized by an identifiable group of signs and symptoms. For example, diabetes and hypertension are classified as diseases, each with specific biological causes and effects.

Illness, on the other hand, reflects a person’s subjective experience of feeling unwell or being in a state of poor health. It encompasses the psychological, emotional, and social aspects of a person’s experience with disease, including how they perceive and respond to their condition. Illness can be influenced by cultural, personal, and societal factors, making it a broader concept than disease, which is more focused on the biological and physiological aspects.

In summary, disease refers to the underlying biological processes, while illness encompasses the personal experience and societal implications of those processes.
