What is the meaning of 'iatrogenic'?

The term 'iatrogenic' refers specifically to any condition or complication that results from the actions of healthcare professionals, typically arising from medical treatment or procedures. This can occur when a medication leads to unintended side effects, a surgical mistake causes additional health issues, or a diagnostic procedure results in injury. Understanding this definition highlights the critical importance of careful medication administration, thorough communication, and precision in medical interventions to minimize such occurrences.

The other choices address different aspects of health and disease. Environmental factors contribute to various diseases but do not specifically relate to the consequences of medical treatment. Identifying an illness using tests pertains to diagnostic methods and does not imply a negative outcome resulting from a healthcare intervention. Lastly, a condition with no identifiable cause relates to idiopathic diseases, distinguishing them from iatrogenic conditions that have a direct link to medical actions.
