A Clinical Overview Understanding of Fever Pathophysiology, Diagnosis and Treatment

Since ancient times, fever has been a common symptom of illness. Fever is a complex physiological response mediated by cytokine-induced hypothalamic prostaglandin production, serving as a defence mechanism against infections. The central nervous system uses endocrine, neurological, immunological and behavioral systems to control the fever response. In addition to a controlled increase in body temperature, fever frequently manifests as a variety of illness-related behaviors, modifications to the physiological and metabolic properties of bodily systems, and adjustments to immunological responses. Therefore, fever and the febrile response continue to play important roles in the etiology, clinical manifestation, and prognosis of several illnesses and disorders. A process known as a fever or pyrexia occurs when the body's normal temperature rises above equilibrium. Accurate diagnosis involves a thorough history, physical examination, and targeted investigations. Treatment focuses on managing the underlying cause and providing symptomatic relief, with antipyretics playing a key role in patient comfort.
