Eosinophilic Oesophagitis (EoE): Symptoms, Causes and Management in the UK

Eosinophilic Oesophagitis, often abbreviated to EoE, is an increasingly recognised chronic condition where the lining of the oesophagus (the tube connecting your mouth to your stomach) becomes inflamed. Unlike standard acid reflux, this inflammation is caused by a specific type of white blood cell called eosinophils.

Under normal circumstances, eosinophils are not found in the oesophagus. However, in people with EoE, the body reacts to certain triggers—usually food allergens or environmental factors—by sending these cells to the oesophageal lining. Over time, this immune response causes the tissue to swell, redden, and eventually thicken or scar, a process known as remodelling. According to British Society of Gastroenterology and NICE-recognised pathways, early intervention is key to managing this condition effectively.

The symptoms of EoE can often be mistaken for GORD (Gastro-oesophageal reflux disease), but there are distinct differences. In adults, the most common signs include:

• Dysphagia: This is the medical term for difficulty swallowing. You may feel like dry or solid foods (such as meat or bread) take a long time to go down.
• Food Impaction: This occurs when food becomes physically stuck in the food pipe, sometimes requiring an emergency hospital visit.
• Chest Pain: A central chest pain that does not always respond to standard antacids.
• Regurgitation: Undigested food coming back up into the throat.
• Adapting Eating Habits: Many patients unconsciously develop 'compensatory behaviours', such as cutting food into tiny pieces, chewing excessively, or drinking large amounts of water to 'wash' food down.

While the exact cause is still being researched, EoE is widely considered an allergic or immune-mediated condition. It is frequently associated with the 'atopic triad'—asthma, eczema, and hay fever. If you have a history of these conditions, you may be at a higher risk of developing EoE.

The triggers are most commonly proteins found in food. The 'Big Six' allergens often implicated include milk, wheat, eggs, soy, peanuts/tree nuts, and fish/shellfish. In some cases, environmental allergens like pollen or dust mites can worsen the inflammation, leading to seasonal flares of swallowing difficulties.

If you suspect you have EoE, the primary method of diagnosis in the UK is through a gastroscopy (an endoscopy of the upper digestive tract). During this procedure, a gastroenterologist will look for characteristic signs such as rings, furrows, or white patches on the oesophageal wall.

Crucially, biopsies must be taken. A diagnosis of EoE is confirmed if a pathologist identifies a high concentration of eosinophils (usually 15 or more per high-power field) in the tissue samples. It is important to distinguish this from simple acid reflux, as the treatments differ significantly.

Management of EoE in the UK typically follows three main pillars: medication, dietary management, and, in some cases, physical dilation.

Medication

• Proton Pump Inhibitors (PPIs): Drugs like omeprazole or lansoprazole are often the first line of treatment. While they primarily reduce acid, they also have anti-inflammatory effects that can help some EoE patients.
• Topical Steroids: These are not inhaled, but rather swallowed. In the UK, specialised formulations like Jorveza (budesonide orodispersible tablets) are frequently prescribed to coat the oesophagus and reduce inflammation directly.

Dietary Management

Working with a dietitian, patients may attempt an 'elimination diet'. This involves removing common triggers (like dairy or gluten) to see if the oesophageal lining heals. This is often a long-term strategy to avoid life-long medication.

If you are experiencing persistent difficulty swallowing or feel that food is 'catching' in your chest, it is important to seek medical advice. You can speak to a GP online to discuss your symptoms and determine if a referral to a specialist is necessary.

An online doctor can review your clinical history, discuss any associated allergies like asthma or eczema, and provide advice on initial management while you await further diagnostic tests. Getting a private GP consultation can often help you understand the next steps in the UK healthcare system, ensuring you are directed to the right specialist for a gastroscopy if required.

EoE is a chronic condition, meaning it requires long-term management rather than a one-off cure. If left untreated, the persistent inflammation can lead to strictures (narrowing of the oesophagus due to scar tissue). This can make eating increasingly difficult and dangerous.

However, with the right combination of dietary awareness and medication, most people with EoE live normal, healthy lives. Regular follow-ups with a gastroenterologist and maintaining a consistent treatment plan are vital for preventing complications.
