Patients with enterocolitis are in the acute phase of disease development for 3-5 days after the onset of the disease, during which the inflammatory response is more pronounced and therefore recurrent fevers may occur. After the fifth day, the disease gradually transitions to the recovery phase, and the patient’s body temperature stabilizes. However, some patients with enteritis may also have recurrent fevers due to other pathological reasons, commonly the following: 1. Recurrent enteritis: Most acute enteritis is caused by infections, commonly bacterial, fungal, viral, parasitic infections caused by unclean diet, and patients may show nausea, vomiting, diarrhea, etc. The disease can cause an inflammatory response in the organism, followed by fever. Therefore, when patients are inadvertently exposed to infected related foods and poisons again, it can cause persistent attacks of enteritis and cause recurrent fever; 2. Infection: Patients with enteritis have relatively low immunity during the onset of the disease, so they are prone to secondary infectious diseases, which can cause recurrent fever. If the patient’s temperature exceeds 38.5°C for a long time, he or she needs to be promptly tested for the presence of other pathogenic bacteria under the guidance of a physician for symptomatic treatment. 3. Inflammatory bowel disease, Crohn’s disease: Patients with recurrent episodes of enteritis and with low-grade fever need to be highly alert to the possibility of Crohn’s disease and ulcerative colitis disease. If patients have spasmodic pain in the right lower abdomen or around the umbilicus, mucopurulent stools, abdominal masses, etc., they should undergo colonoscopy, barium enema and other examinations under the guidance of a doctor.
