Your Care Instructions

Mesenteric adenitis is pain caused by swollen lymph nodes in the belly. In most cases, it is caused by the body's reaction to an infection. Symptoms are often like those from appendicitis. Your child may have belly pain, nausea, and vomiting. But this condition almost always gets better on its own.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

  • Make sure your child rests.
  • Give your child lots of fluids. This is very important if your child is vomiting or has diarrhea. Give your child sips of water or drinks such as Pedialyte or Infalyte. These drinks contain a mix of salt, sugar, and minerals. You can buy them at drugstores or grocery stores. Give these drinks as long as your child is throwing up or has diarrhea. Do not use them as the only source of liquids or food for more than 12 to 24 hours.
  • You may find that it helps to put a warm water bottle, a heating pad set on low, or a warm cloth on your child's belly.
  • Ask your doctor if you can give your child acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) for pain. Be safe with medicines. Read and follow all instructions on the label.
  • If the doctor prescribed antibiotics for your child, give them as directed. Do not stop using them just because your child feels better. Your child needs to take the full course of antibiotics.

When should you call for help?

Call your doctor now or seek immediate medical care if:

  • Your child has new or worse belly pain.
  • Your child has a fever.
  • Your child is vomiting.
  • Your child cannot pass stools or gas.

Watch closely for changes in your child's health, and be sure to contact your doctor if your child has any problems.
