The pharmaceutical industry develops, manufactures, and sells drugs. Defining illness is not its mission. Generally, the medications produced by drug companies target diseases that have been defined previously by the medical profession. However, there are several indirect ways in which the industry contributes to the definition of illness. Are these contributions beneficial to society and ethically sound, or are they solely aimed at maximizing corporate profit? To address these questions, I analyze some examples of how the pharmaceutical industry has played a role in defining illness.

No sharp line divides health from disease. Defining an illness is a complex process, and definitions typically evolve over time, facilitated by advances in science and validated by societal recognition. Thus, it is expected that the definition of what constitutes disease will change with time, with additions (e.g., Lyme disease), subtractions (e.g., homosexuality), and modifications (e.g., autoimmune disorders). While some of these modifications are universally accepted, others—particularly those regarding conditions that lack objective signs or laboratory abnormalities—are controversial. The term “medicalization” was introduced in the 1970s by Illich and others [1] to challenge the characterization of normal variation among humans as disease. However, defining illness can be the first step toward reducing human suffering. Thus, medicalization can alternatively be defined as “a process by which human problems come to be defined and treated as medical problems” (Ref : AMA Journal of Ethics)
