Most acute enteritis causes fever because acute enteritis is mostly caused by viral or bacterial infections that produce endogenous thermogenic factors that cause fever. Acute enteritis is one of the more common types of digestive disorders and is usually triggered by the consumption of unclean, cold or spicy irritating foods, or due to food allergies, chemical and drug poisoning. The clinical manifestations are usually abdominal pain, diarrhea, nausea, vomiting, abdominal distension, and in severe cases, fever, dehydration, electrolyte disturbance, and even shock. When a patient with acute enteritis develops fever with diarrhea, if the body temperature does not exceed 38.5℃, physical cooling and oral antibiotic drugs and antidiarrheal drugs, such as ofloxacin tablets, norfloxacin capsules, montelukast, etc., can be administered first. If the body temperature exceeds 38.5℃, you should go to the hospital for treatment to exclude fever caused by other diseases and to prevent dehydration symptoms caused by high body temperature. Pay attention to the cleanliness and hygiene of the diet, eat less cold and stimulating food, and eat on time.
