Introduction
Gastroenteritis accompanied by fever may be caused by pathogenic microbial infection, in which the immune system activates its defense mechanisms to engulf pathogens, leading to the production of endogenous pyrogens. It could also result from indigestion due to poor dietary habits, causing food to remain in the gastrointestinal tract for prolonged periods and giving rise to damp-heat in the spleen and stomach. Additionally, it may occur when the disease persists for a long time, weakening the body and reducing immune function, making the individual susceptible to bacterial invasion.
Gastroenteritis may cause fever, typically due to pathogenic infections, food indigestion (indigestion), or decreased immunity.
1. Pathogenic Infection
It may be caused by infection with pathogenic microorganisms such as fungi, viruses, or bacteria. The body's immune system activates its defense mechanisms to engulf the pathogens, leading to the production of endogenous pyrogens, which results in elevated body temperature. This may also be accompanied by symptoms such as fatigue and chills.
2. Food Indigestion (Indigestion)
After developing gastroenteritis, not paying attention to diet—such as consuming hard-to-digest foods or overeating—may lead to food stagnation. When food remains in the gastrointestinal tract for prolonged periods, it can generate damp-heat in the spleen and stomach, contributing to symptoms.
3. Decreased Immunity
Neglecting gastroenteritis may prevent timely recovery, leading to prolonged illness, physical weakness, and reduced immune function, making the body more susceptible to bacterial invasion.
Additionally, inflammatory stimulation may also cause fever. It is recommended to maintain good dietary hygiene in daily life and engage in appropriate physical exercise to enhance immunity, which helps prevent the occurrence of gastroenteritis.
