Abdominal lymphadenopathy needs to go to the hospital as soon as possible to complete relevant examinations to determine the cause of lymphadenopathy. Generally, blood routine examination, C-reactive protein, color ultrasound, etc. are required. If bacterial infection is considered to be the cause, antibiotics need to be given for treatment. Common drugs include cephalosporins, or penicillin antibiotics. If it is considered that it is caused by virus infection, it needs to be actively treated with antiviral drugs. At the same time, it can be treated with oral Chinese medicine, with good effect. If it is considered to be caused by allergic factors, it is necessary to get rid of the allergen and take oral desensitization drugs for treatment. If it is considered that it is caused by lymph node metastasis of malignant tumor, it is necessary to search for the primary tumor, then perform radical resection of the tumor, and then cooperate with lymph node dissection. Later, chemotherapy, targeted drug treatment, etc. may be required.
