The lymph nodes are part of the immune system. They help clear infectious and damaged tissue out of an infected area. Lymph nodes swell when an infection is near and the nodes are active.
Mesenteric adenitis is most often caused by an infection in the stomach or intestines. Viruses are the most common cause of these infections, but some may be due to bacteria.
Children are at increased risk of developing mesenteric adenitis.
Symptoms often follow a cold and may include:

- Wash your hands often, especially when you come in contact with someone who is sick. Wash your hands for 15-20 seconds with soap and water. Rubbing alcohol-based cleaners on your hands is also helpful.
- Avoid close contact with people who are sick.
