Inflammation of gastrointestinal lymph nodes, or mesenteric lymphadenitis, is mainly due to low immunity, displacement of intestinal flora, acute gastroenteritis and other factors, resulting in the onset of retrograde bacterial infection of mesenteric lymph nodes. The clinical symptoms are usually abdominal pain, diarrhea, constipation, etc. The common treatment is mainly based on medication.1. Oral medication: Oral anti-inflammatory and anti-infective medication can be taken under the guidance of a professional doctor, such as amoxicillin, norfloxacin, penicillin V potassium tablets, cephalosporin, etc. Analgesic medication is also needed to relieve symptoms, such as atropine, compound belladonna tablets, scopolamine, etc. If there are obvious diarrhea symptoms at a later stage, montelukast can be given for symptomatic management; 2. Intravenous injection: If oral medication does not relieve the symptoms, or if the patient has local inflammatory symptoms, intravenous drip anti-inflammatory medication is needed for treatment, such as meloxicillin, cephalosporin and other drugs. Patients with more serious conditions, such as high fever, can also be combined with small doses of glucocorticoid injections, such as dexamethasone sodium phosphate injection to relieve symptoms. Patients should pay attention to diet regulation during the recovery period, pay attention to dietary hygiene, prohibit smoking and alcohol, and avoid eating spicy and stimulating foods, so as not to increase the burden on the intestinal tract, which is not conducive to recovery. Take more rest and use hot towels to warm the abdomen to help relieve the symptoms of abdominal pain. Maintain the appropriate temperature and humidity in the living room to make the body and mind feel comfortable.
