What causes mesenteric adenitis

Condition analysis:
Mesenteric adenitis is a condition that more often affects children and teenagers. It causes inflammation and swelling in the lymph nodes inside the abdomen. Lymph nodes are small, bean-shaped organs that contain white blood cells called lymphocytes. They are part of your body’s lymphatic system. Lymph nodes play an important role in the immune system. They filter out bacteria and other germs from the lymph fluid so your body can remove these harmful substances.

Mesenteric adenitis affects lymph nodes in tissue called mesentery. This tissue connects the intestines to the abdominal wall. Another name for mesenteric adenitis is mesenteric lymphadenitis.

Instructions:
Causes: A bout of the stomach flu or another infection in your abdomen can cause inflamed and swollen lymph nodes in and around the mesentery. Again, this is the tissue that attaches your intestines to the abdominal wall.

When you get an infection, bacteria, viruses, or other germs filter through your lymph nodes and cause them to become inflamed and swell up. Lymph nodes are part of the body’s immune response. They capture bacteria, viruses, and other germs, and they clear them out of your system to prevent you from getting sick. That’s why you’ll sometimes feel enlarged, swollen lymph nodes in your neck or other places when you’re sick.
