Etymology
The term 'pathophysiology' is derived from three Greek roots: 'pathos,' meaning disease or suffering; 'physio,' meaning nature or function; and 'logia,' referring to the study of a subject. The word began to be used in the 19th century as the medical field expanded its focus not just on the symptoms of diseases, but also on understanding the underlying biological mechanisms. Earlier works in physiology provided a foundation for this field, where researchers sought to explain how disturbances in normal bodily functions contribute to illness. Over time, pathophysiology has become an essential component of modern medicine, helping healthcare professionals understand the complexities of various diseases and informing treatment plans.
