Etiology is the study of the causes or origins of diseases, disorders, or conditions. It involves examining various factors, such as genetic, environmental, and lifestyle influences, that contribute to the development of a particular disease or condition. Researchers in etiology aim to understand the underlying mechanisms that lead to the onset and progression of various health issues, with the goal of ultimately finding ways to prevent, treat, or cure them. This field is important in advancing medical knowledge and improving public health outcomes.
