Eosinophilic gastritis (EG) is a condition that results in inflammation of the stomach. It can make it hard for the body to get enough nutrients from food.
EG may happen in cycles. Symptoms may fade or stop for a time and then may flare up again.
EG is caused by a build-up of white blood cells called eosinophils. These cells are part of the immune system. They cause inflammation when there is an infection or injury in the body. With EG, the eosinophils build-up in tissue when they are not needed. This leads to long-term inflammation. Over time, this damages tissue and causes ulcers and polyps in the colon.
It is not clear what causes EG. It is likely due to genetics and the environment. It may also be linked to an allergic reaction.
Things that may increase a child’s risk of this problem are:
The doctor will ask about your child’s symptoms and health history. A physical exam will be done. EG can be hard to diagnose with tests. Other issues of the stomach or intestines can cause similar problems. Tests to rule out other conditions are:
Endoscopy—a scope is passed through the mouth to the stomach to view the area
A biopsy is the only way to confirm EG. A sample of the stomach will be removed and tested to look for eosinophils.
