Eosinophilic esophagitis (EoE) is a condition wherein eosinophil, a type of white blood cell, accumulates in the esophagus, causing inflammation. It is typically accompanied by other symptoms, such as chest pain, difficulty swallowing (dysphagia), and vomiting. The condition often results from food allergies or environmental triggers. Thus, it helps to eliminate certain foods and add them back individually to identify any allergies. Here are some foods that may trigger EOE: Dairy products Even generally, milk is associated with increased mucus production, leading to congestion among people with lactose intolerance. Dairy intolerance can also cause or aggravate EoE. While some patients may react to dairy in all its forms, some others may be able to have certain dairy products, like baked items, without any consequences. Thus, it also helps to eliminate all dairy products initially and add them back one by one to identify the level of lactose intolerance. Fish and shellfish Fish and shellfish may also act as allergens for patients with EoE. Individuals with shellfish allergies often experience swelling of the throat and difficulty breathing. So, eliminating fish and shellfish and adding them back can help determine if either or both are causing the disease. Eggs Eggs contain specific properties that release histamine, a significant agent in mucus production, in the body.
