Rare diseases typically display a high level of symptom complexity and variability. Individuals diagnosed with the same rare disease may be impacted differently and each person’s experience is unique. Please seek support from qualified healthcare professionals to learn more about the most suitable care and support options for you.

Emergency Management

There may be special considerations for the emergency management of individuals living with Eosinophilic Gastrointestinal Diseases (EGIDs) presenting to emergency departments.

Individuals with Eosinophilic Oesophagitis (EoE), a type of EGID, may present to emergency departments with food impactions. When treating patients with EoE, it is important to refer to their emergency and management plans:

Clinical Care Guidelines

General clinical care guidelines for Eosinophilic Gastrointestinal Diseases (EGIDs) as a whole are yet to be developed in Australia, but the following guidelines and recommendations are available:


Eosinophilic Gastrointestinal Diseases (EGIDs) are inflammatory conditions in which large numbers of eosinophils (a type of white blood cell that is part of the body’s immune system) infiltrate and accumulate in the gut (gastrointestinal tract), causing inflammation and tissue damage.1 This may be due to an allergic response to food, environment, or other unknown triggers. EGIDs can occur in various parts of the , resulting in the different conditions.1,2 Symptoms will depend on the type of EGIDs.1

According to the 2022 International consensus for EGID terminology:2

  • Eosinophilic Oesophagitis (EoE) involves the oesophagus
  • Eosinophilic Gastritis (EoG) involves the stomach
  • Eosinophilic Enteritis (EoN) involves the small bowel/intestine;
  • Eosinophilic Duodenitis (EoD) involves the duodenum
  • Eosinophilic Jejunum (EoJ) involves the jejunum
  • Eosinophilic Ileitis (EoI) involves the ileum
  • Eosinophilic Colitis (EoC) involves the colon/large intestine

EoE is the most commonly known EGID, but there is increasingly more awareness of and research into the non-EoE EGIDs.1,2 In the past, the term ‘Eosinophilic Gastroenteritis’ has been widely used in a non-standardised manner, often to represent when any part of the gastrointestinal tract is affected, resulting in confusion in clinical and research settings.2 It is now recommended that the term ‘Eosinophilic Gastroenteritis’ is only used for the condition in which both the stomach and small bowel/intestine are involved and ‘EGID’ should instead be used as the umbrella term for ‘diseases of the GI tract with pathologic eosinophilic infiltration in the absence of secondary causes’.2

The symptoms of Eosinophilic Gastrointestinal Diseases (EGIDs) may vary depending on which part of the gut is affected.1,3

Please speak to your medical team to learn more about the specific symptoms and complications of a particular EGID.

More information on symptoms associated with EoE can be found at the RARE Portal: Eosinophilic Oesophagitis (EoE)


The cause of Eosinophilic Gastrointestinal Diseases (EGIDs) is not well-understood, but is thought to be caused by an allergy to food.3


Diagnosis of an eosinophilic gastrointestinal disease (EGID) should be considered in the presence of gastrointestinal symptoms with no obvious cause.3 An endoscopy is usually performed by a gastroenterologist and involves the insertion of an endoscope (a tube with a light and attached camera) to examine the gastrointestinal tract.1 Tissue samples (biopsies) are often taken to identify if there is accumulation of eosinophils (a type of white blood cell). Other possible causes of the gastrointestinal symptoms and increased presence of eosinophils will also need to be ruled out.3


EGIDs are chronic conditions that require ongoing management monitored by a multidisciplinary medical team.1 This may include medication or making dietary changes, such as an elimination diet to identify if the EGID is caused by a food allergen, which should only be done with advice from medical professionals.

It is best to speak with your medical team to learn more about the possible treatment or management strategies for your EGID condition and its associated symptoms. Treatment will depend on an individual’s specific symptoms and complications.

Clinical Care

Healthcare professionals involved in the treatment of EGIDs may include general practitioners (GP), gastroenterologists (stomach/bowel medical specialists), clinical immunology/allergy specialists and specialist dietitians.2 The need for different healthcare professionals may change over a person’s lifetime and extend beyond those listed here.


ausEE Inc.: Research provides information about research on EGIDs in Australia, including funding for medical research grants.

Please visit Australian Clinical Trials to learn more about clinical trials for EGIDs in Australia; there may not be any clinical trials currently available.

Information regarding clinical trials for EGIDs in other countries can be found at ClinicalTrials.gov; there may not be any clinical trials currently available.

It is best to discuss your interest in any clinical trials with your medical team to determine suitability and eligibility.
