Children with swollen abdominal lymph nodes can be treated with the following measures: First, cephalosporin can be administered to the child. If the swollen abdominal lymph nodes are caused by acute lymphadenitis and the white blood cell count in the child’s blood is significantly high, mainly due to bacterial infection, the child can be given cephalosporin to relieve the swollen lymph nodes. Second, the child needs to be given chemotherapy in a timely manner. If the swollen abdominal lymph nodes are caused by lymphoma, the child will also have swollen lymph nodes in the neck, armpits, groin and other parts of the body, which will also cause high fever in the child, and chemotherapy should be used in a timely manner to resolve the swollen abdominal lymph nodes at the root. Therefore, how to treat swollen abdominal lymph nodes in children depends on the specific type of disease.
