What is pathophysiology?

Pathophysiology is defined as the study of how diseases affect the functions of the body. This field examines the biological and physiological mechanisms that underlie disease processes and how they influence normal body functions. Understanding pathophysiology is crucial for healthcare professionals, as it provides insight into the alterations caused by diseases, enabling them to devise effective treatment strategies and manage patient care effectively.

The focus of pathophysiology is on the dysfunction and abnormalities that arise due to various disease states, examining both the clinical manifestations of these conditions and their underlying causes. By studying the changes associated with different illnesses, practitioners can better understand patient symptoms and progression, which aids in diagnosis and treatment planning.
