Emergency Management

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

Individuals with EoE 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

The following guidelines and recommendations are available regarding clinical care of Eosinophilic Oesophagitis (EoE):

Below are guidelines from other countries:


ICD11: DA24.1



Eosinophilic Oesophagitis (EoE) is the most well-known type of Eosinophilic Gastrointestinal Disease (EGID).1 It is an inflammatory condition 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 lining of the food pipe (oesophagus) that connects the mouth to the stomach.1,2 This may be due to an allergic response to food, environment, or other unknown triggers.

EoE can cause difficulties in feeding or swallowing food, food getting stuck in the oesophagus (food impaction or food bolus obstruction (FOB)), nausea, persistent vomiting, and stomach and chest pain, among other symptoms.1-3

EoE can affect both children and adults.3 There has been some reported cases of family history with EoE.3 People with EoE may often have other allergic conditions such as asthma, hay fever or eczema.1-3

Personal stories can be found at ausEE Inc. (EOSaware): My EoE Stories.


Symptoms of EoE may present in infants or may arise in older children and adults.2 The symptoms vary between individuals, and may include:1-3

  • Feeding difficulties (slow chewing of food, needing pureed food, avoidance of certain textures, oral aversion to food)
  • Poor appetite or not wanting to eat
  • Difficulty in swallowing food and/or regularly requiring a drink whilst eating
  • Food getting stuck in the eosophagus when eating, also known as food impaction/Food Bolus Obstruction (FBO)
  • Nausea, persistent choking or gagging on food, retching, and vomiting/regurgitation of food
  • Stomach (abdominal) pain or chest pain
  • Severe acid reflux (heartburn) that does not respond to medications
  • Failure to thrive/poor weight gain

EoE can also lead to scarring and narrowing of the oesophagus (stricture).1,2

Please speak to your medical team to learn more about the symptoms and complications of EoE.


EoE may be caused by an allergy to food or the environment, and in some cases, the exact cause may be unknown.1 There has been some reported cases of family history with EoE.3


A diagnosis of eosinophilic oesophagitis (EoE) should be considered in the presence of chronic symptoms of oesophagus dysfunction.3 Diagnosis of EoE usually involves an endoscopy and biopsies performed by a gastroenterologist.1-3 The endoscopy involves the insertion of an endoscope (a tube with a light and attached camera) to examine the oeosphagus and to take tissue samples (biopsy). The tissue samples are examined by a pathologist to identify if there is accumulation of eosinophils (a type of white blood cell) – the presence of more than 15 eosinophils per high-power field (hpf) is indicative of EoE;1,3 however other possible causes of increased eosinophils still need to be ruled out.3

The Updated International Consensus Diagnostic Criteria for Eosinophilic Esophagitis (Proceedings of the AGREE Conference)3 was developed in 2018 by paediatric and adult physicians and researchers from gastroenterology, allergy, and pathology subspecialties representing 14 countries, including Australia.


EoE is a chronic condition that require ongoing management and monitoring supervised by a multidisciplinary medical team.1 Treatment and management of EoE may include dietary changes, medication and endoscopic interventions.1,2 Regular endoscopies and repeat biopsies may be required to monitor the condition.

Dietary changes should only be made under the direction and supervision of the appropriate medical professional.2 This may include elimination diets to identify if EoE is caused by a food allergen or an elemental diet to replace food intake with a liquid formula.1,2 Medications for EoE may include swallowed corticosteroids to reduce inflammation and proton pump inhibitors to reduce acid production as well as for its anti-inflammatory effect; whilst endoscopic interventions such as oesophageal dilation (to widen the oesophagus) may be used in specific cases when the oesophagus is very narrow.1,2

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

Clinical Care

Healthcare professionals involved in the treatment of EoE 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.
