Patient's question:
Today I had discomfort in the upper abdomen. I ate some seafood and then took a nap under the air conditioner. By the third day, I developed a high fever that wouldn't go down. I have previously had respiratory infections that led to pneumonia, but it wasn't very serious. I received timely treatment, and now I'm still running a high fever. My urination and defecation are normal, and a thorough examination showed nothing significant, but the fever won't go down.What kind of assistance is needed: What could be the cause of the fever?
Doctor's answer:
The cause of fever is due to the action of fever-inducing agents on the body, which subsequently leads to the production of endogenous pyrogens (EP) being attributed to the brain for temperature regulation information feedback diagram. The temperature regulation center is further affected, leading to the release of fever mediators and consequently causing a shift in the set point, ultimately resulting in fever. Common fever-inducing agents include exogenous pyrogens originating from outside the body, such as bacteria, viruses, fungi, spirochetes, and Plasmodium; as well as those originating from within the body.
