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

Lymph nodes are part of the body's lymphatic system and function to filter out microorganisms. Therefore, when bacteria are present, the lymph nodes may become inflamed and swollen. When children develop abdominal lymph node swelling, it is primarily due to infection causing mesenteric lymphadenitis. This condition requires timely treatment with anti-infective agents and antibiotics. During treatment, patients should avoid consuming spicy or irritating foods.
