What should be done if a child has lymph nodes in the abdomen?

Abdominal lymph nodes in children should be evaluated to determine the underlying cause, followed by appropriate treatments such as general management, medication, or surgical intervention to resolve the condition. Children with abdominal lymph nodes should pay attention to their diet and avoid raw or cold foods. Applying warm compresses may help. If persistent nausea, vomiting, or diarrhea occurs, fasting may be necessary. Most cases of abdominal lymph node enlargement in children are caused by viral or bacterial infections. Under a doctor's guidance, specific antimicrobial or antiviral medications—such as amoxicillin-clavulanate potassium, ceftriaxone sodium, ribavirin, or acyclovir—can be selected based on the identified pathogen. In some cases, abdominal lymphadenopathy is secondary to conditions like appendicitis. If appendicitis is confirmed as the cause, surgical removal of the appendix may be recommended to prevent severe complications such as peritonitis. Children with abdominal lymph nodes should promptly visit the surgery department at a正规 hospital for evaluation, including blood tests, abdominal ultrasound, or CT scans, to identify the cause and receive targeted treatment accordingly.
