Eosinophilic gastroenteritis (EGE) is the buildup of white blood cells called eosinophils in the stomach and intestine linings. EGE can lead to inflammation, tissue damage, ulcers, and polyps. Damage to the tissue can make it difficult to absorb nutrients from food.

EGE may occur in periods without symptoms and periods when symptoms are severe.


It is not clear what causes EC. It is likely a blend of genetics and the environment.

Eosinophils are part of the immune system response to problems in the body. Part of their normal function is to cause inflammation that helps trap harmful material. With EGE, eosinophils build up when it is not needed or remains longer than needed and causes unnecessary inflammation. It is not clear what causes the buildup. It may be linked to the presence of an allergen.

Risk Factors

Factors that may increase your child’s chances of EGE include:


Symptoms may include:

  • Severe abdominal pain
  • Bloating
  • A feeling of fullness after eating a small amount
  • Heartburn
  • Nausea
  • Vomiting
  • Diarrhea, with or without blood
  • Fatigue
  • Problems feeding in infants

Complications may include:

  • Malnutrition
  • Weight loss
  • Anemia or iron deficiency from blood loss


You will be asked about your child’s symptoms and medical history. A physical exam will be done. EGE is hard to diagnose with simple tests. However, some tests may be able to rule out other diseases with similar symptoms.

Tests to rule out other conditions may include:

  • Blood tests
  • Allergy tests
  • Endoscopy—a lighted tube with a camera is used to look at the stomach and small intestine

A biopsy is the only way to confirm EGE. During a biopsy, tissue samples from an endoscopy are studied under a microscope to confirm a diagnosis.

EGE cannot be cured. For some people, removing cow’s milk and soy from the diet might manage symptoms. This is mainly true for infants.

Treatment focuses on managing symptoms to decrease damage to tissue. Treatment options may include:

Foods that cause symptoms will need to be avoided. Proteins, such as soy, nuts, eggs, or milk are common allergens. A dietitian can help to guide dietary needs. Some complications include:

  • If all proteins need to be removed, then only the building blocks called amino acids can be consumed. Liquid formulas may be needed. In some cases, a feeding tube may be used.
  • A nutritional support program may be needed to support growth. This may include vitamins and supplements.

Medications are used to manage EGE and treat complications. These may include:

  • Oral steroids to reduce inflammation during symptom flare ups
  • Medications to boost, change, or suppress the effects of the immune system
  • Medications to reduce stomach acid
  • Iron pills to treat anemia

Medications to manage allergies or asthma may also be needed.

If the opening from the stomach to the small intestine becomes too narrow or blocked, then surgery will be needed to fix it.


There are no current guidelines to prevent EGE because the cause is unknown.
