Mesenteric Adenitis

Medically reviewed by Last updated on Jan 5, 2023.

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.


Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.

Prevent mesenteric adenitis:

  • Wash your hands. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food.
  • Cook meats all the way through. Use a meat thermometer to make sure meat is heated to a temperature that will kill bacteria. Do not eat raw or undercooked chicken, turkey, seafood, beef, or pork.
  • Drink safe water. Drink only treated water. Do not drink water from ponds or lakes.
  • Drink safe milk. Drink only pasteurized milk. Do not drink raw milk.

Contact your healthcare provider if:

  • Your symptoms return.
  • You have questions or concerns about your condition or care.

Return to the emergency department if:

  • You pass very little urine.
  • You cannot pass a bowel movement or gas.
  • You are extremely thirsty.
  • You become pale, exhausted, or sweaty without effort.
  • You have swelling in your abdomen.
