What is the Difference Between Disease and Illness?

The terms "disease" and "illness" are often used interchangeably, but they have distinct differences:

• Disease: A disease is an abnormality in the function and/or structure of body organs and systems. It is a scientific concept and can be diagnosed by a medical expert. Diseases have a specific result on a body part or function and are often identified by a pathological identification label or marker, such as diabetes, sickle-cell anemia, or lupus.
• Illness: Illness is an experience of discontinuities in states of being and perceived role performances. It is a personal experience and can vary tremendously between individuals with the same disease. Illness can be a perceived notion of unwellness or derive from self-diagnosis. It can affect the body or mind in various ways and is often manageable through alternative treatments and lifestyle changes.

In summary, a disease is a specific medical condition with identifiable symptoms and effects on the body, while an illness is a personal experience of unwellness or discomfort. Understanding the difference between disease and illness is crucial for proper diagnosis and treatment.
