Large abdominal lymph nodes are usually caused by abdominal inflammation, abdominal tumor and other diseases, which should be treated according to the cause. 1. Abdominal inflammation: generally due to bacterial infection caused by abdominal inflammation, inflammation spread to the lymph nodes, causing lymph node enlargement, usually abdominal pain, fever and other symptoms, patients can take levofloxacin, amoxicillin and other drugs under the guidance of the doctor for treatment, which is prohibited for patients with allergies to these drugs. For abdominal tuberculosis lymphadenitis, it is also necessary to combine the application of isoniazid, rifampicin, ethambutol and other anti-tuberculosis drugs according to the course of treatment. 2. Abdominal tumors: malignant tumors, such as gastric cancer, intestinal cancer, etc., may cause lymphatic metastasis to abdominal lymph nodes, resulting in lymph node enlargement. It is suggested that patients should go to the hospital for timely examination and under the guidance of doctors, undergo microlaparoscopic and open surgery to remove the tumor, and after surgery, they should be treated with radiotherapy according to their conditions. Enlarged abdominal lymph nodes may also be caused by parasitic infection, connective tissue disease, lymphoma and other factors. Therefore, once found that the abdominal lymph nodes are enlarged, we should complete the examination, clarify the condition and then follow the doctor’s instruction to treat accordingly. We suggest that patients should go to the hospital for examination and symptomatic treatment under the guidance of the doctor, and at the same time avoid eating spicy and stimulating food.
