Enterocolitis fever is a fever in which the patient has a fever based on enterocolitis. Enteritis is caused by bacterial, viral, fungal, or other pathogens that cause small bowel and colitis. The main symptoms are abdominal pain, diarrhea, and mucus and blood stools, and in severe cases, diarrhea can be more severe. For example, in the case of small bowel inflammation, shock may occur, especially in children, because of the relatively large amount of fluid loss. Therefore, if enterocolitis occurs, you should seek medical attention in severe cases. During the onset of enteritis, the patient develops a fever, which means that the body temperature rises, the replication or activity of microorganisms such as pathogens is not as active as before, the body’s immune system is elevated at this time, and many useful cells such as phagocytes and neutrophils come into play to fight the pathogens, so the process of fever is actually a protective mechanism for the body. If the fever is not too high, sometimes it is not recommended to give the patient or child a random fever reduction, but if a high fever occurs, especially in children, and the body temperature exceeds 39°C, it is recommended to give antipyretic treatment, but in the process of antipyretic treatment, pay attention to rehydration, do not lose fluids because of fever, and enteritis, and lead to fluid loss shock.
