Fever

Fever is a common symptom characterized by an increase in body temperature above the normal range, usually in response to an underlying illness or infection.

It is considered a physiological defense mechanism that helps the body fight off invading pathogens and enhances immune response.

Fever is typically caused by the release of chemicals called pyrogens from infectious agents or damaged cells, which stimulate the hypothalamus in the brain to raise the body’s temperature set point.

As a result, several systemic reactions occur, including increased heart rate and metabolism, shivering, and constriction of blood vessels near the surface of the skin.

While fever itself is generally harmless and acts as a sign that one’s immune system is functioning properly, exceptionally high fevers can lead to complications such as dehydration or seizures and may require medical intervention.

Monitoring and managing fevers through appropriate antipyretic medications, adequate fluid intake, rest, and patient comfort are integral parts of quality healthcare delivery.
