WHAT YOU NEED TO KNOW: What is mesenteric adenitis? Mesenteric adenitis is inflammation of lymph nodes in the tissue that surrounds your intestines. Lymph nodes are organs of the immune system that help absorb bacteria and toxins from your body. It is caused by infection from bacteria, viruses, or parasites. Mesenteric adenitis may cause dehydration and loss of electrolytes (minerals), such as sodium. Rarely, it could lead to sepsis (a serious blood infection) or an abscess (pus-filled wound) on your intestine.
