The term "idiopathic" is used to describe conditions or diseases for which the cause is unknown. In medical terminology, when a disease is labeled as idiopathic, it indicates that despite thorough investigation and research, no specific causative factor can be identified. This is particularly significant because it underscores the complexities of medical science and the limits of our current understanding about the human body and its disorders.

The other terms have distinct meanings that set them apart from the concept of unknown causes. "Congenital" refers to conditions present at birth, which may be due to genetic factors or environmental influences during pregnancy. "Iatrogenic" pertains to health issues that arise as a direct result of medical treatment or interventions. "Acquired" denotes conditions that develop after birth, often influenced by factors such as infections or lifestyle choices. None of these terms convey the absence of knowledge regarding the etiology of a disease in the way that "idiopathic" does.
