Eosinophilic Esophagitis: Symptoms, Causes, Diagnosis and Treatment

Written by Medicover Team and Medically Reviewed by Dr Raosaheb Rathod , Gastroenterologists Medical

Eosinophilic Esophagitis (EoE) is a chronic immune-mediated inflammatory disease in which eosinophils, a type of white blood cell, accumulate in the lining of the esophagus. The condition is often triggered by food allergens or environmental allergens and can affect both children and adults. Common symptoms include difficulty swallowing (dysphagia), food getting stuck in the esophagus (food impaction), chest pain, heartburn, abdominal pain, vomiting, or feeding difficulties in children.

Early diagnosis and appropriate treatment, including dietary modifications, proton pump inhibitors, topical corticosteroids, and esophageal dilation when necessary, are essential to reduce inflammation, prevent scarring, and improve swallowing and quality of life.

What are the Symptoms of Eosinophilic Esophagitis?

Eosinophilic esophagitis causes symptoms such as difficulty swallowing, food getting stuck in the throat, chest pain, heartburn, and, in children, feeding difficulties or poor growth.

Difficulty Swallowing

One of the most common symptoms of EoE is difficulty swallowing, known as dysphagia. This can affect both solids and liquids.

Food Impaction

Food impaction occurs when food gets stuck in the esophagus. This can be a medical emergency and may require immediate attention.

Chest Pain

Chest pain that is not related to heart issues can also be a symptom of EoE. This pain is usually due to inflammation and can be quite severe.

Other Symptoms

Other symptoms may include abdominal pain, nausea, vomiting, and weight loss. Children with EoE may experience feeding difficulties and failure to thrive.

What are the Causes of Eosinophilic Esophagitis?

Eosinophilic esophagitis is mainly caused by an allergic immune response to certain foods or environmental allergens, leading to eosinophil buildup in the esophagus.

Allergens

The most common cause of EoE is an allergic reaction to food or environmental allergens. Foods such as dairy, wheat, soy, and nuts are often implicated. Environmental allergens, like pollen, can also trigger the condition.

Genetic Factors

There is evidence to suggest that genetic factors play a role in the development of EoE. If you have a family history of EoE or other allergic conditions, you may be at higher risk.

Immune System Dysfunction

In some cases, an overactive immune response can cause EoE. This means that the body mistakenly targets the esophagus, leading to chronic inflammation.

When to See a Doctor for Eosinophilic Esophagitis?

Individuals with persistent difficulty swallowing, food sticking in the throat or chest, recurrent heartburn despite treatment, or feeding difficulties in children should consult a Gastroenterologist or Allergist.

How Is Eosinophilic Esophagitis Diagnosed?

The diagnosis of eosinophilic esophagitis is confirmed through endoscopy with biopsy, which shows increased eosinophils in the esophageal tissue along with clinical symptoms.

Medical History and Physical Exam

Your doctor will start with a thorough medical history and physical exam. This helps to rule out other conditions that could cause similar symptoms.

Endoscopy

An endoscopy is often required to diagnose EoE. During this procedure, a small camera is inserted into the esophagus to look for signs of inflammation and take biopsies.

Biopsy

A biopsy involves taking small tissue samples from the esophagus. These samples are then examined under a microscope to check for the presence of high eosinophils.

Allergy Testing

Allergy testing can help identify specific allergens that may be triggering your EoE. This can include skin prick tests or blood tests.

What are the Treatment Options for Eosinophilic Esophagitis?

Treatment options for eosinophilic esophagitis include dietary modifications, proton pump inhibitors, topical corticosteroids, and in some cases, esophageal dilation to relieve symptoms.

Dietary Management

One of the most effective treatments for EoE is dietary management. This often involves eliminating foods that trigger symptoms. Common elimination diets include the six-food elimination diet (SFED), which removes dairy, wheat, soy, eggs, nuts, and seafood.

Medications

Medications can also be used to manage EoE. These may include:

Endoscopic Dilation

In cases where the esophagus has become narrowed, endoscopic dilation may be necessary. This procedure involves stretching the esophagus to make swallowing easier.

What is the Prevention of Eosinophilic Esophagitis?

Prevention of eosinophilic esophagitis focuses on avoiding trigger foods and allergens that cause inflammation in the esophagus. Identifying and managing these triggers, along with following medical advice, can help reduce flare-ups and control symptoms.

Avoiding Known Allergens

One of the best ways to prevent EoE is to avoid known allergens. This can involve making dietary changes and taking steps to reduce exposure to environmental allergens.

Regular Monitoring

Regular check-ups with your healthcare provider can help monitor the condition and make adjustments to your treatment plan as needed.

Lifestyle Changes

Making lifestyle changes, such as maintaining a healthy weight and avoiding smoking, can also help manage EoE symptoms.

What is the Recovery Process for Eosinophilic Esophagitis?

Eosinophilic Esophagitis is a chronic condition that requires ongoing management. Most individuals achieve good symptom control with appropriate dietary changes, medications, and regular follow-up. Long-term treatment helps prevent recurrence, esophageal scarring, and swallowing complications.

Following prescribed medications, adhering to recommended dietary restrictions, attending regular gastroenterology follow-up appointments, monitoring swallowing symptoms, maintaining adequate nutrition, and seeking prompt medical attention for food impaction help support long-term disease control and esophageal health.
