Nasal discharge from food allergies: causes and solutions to the problem
About the symptom
Watery eyes from food allergies is one of the common symptoms that can occur in response to the consumption of certain foods. An allergic reaction to food occurs when the immune system mistakenly perceives certain proteins as a threat and begins to produce antibodies. This can lead to various reactions, including tearing, itchy eyes, and conjunctival swelling. Often, such symptoms arise in conjunction with other manifestations of allergy, such as rashes, fatigue, and stomach discomfort.
Frequently, tearing is a consequence of inflammation that triggers the allergic response in the body. In such cases, when the allergenic food enters the body, the release of histamine and other chemicals may occur, provoking the dilation of blood vessels and increasing tissue permeability. As a result, this can lead to the accumulation of fluid in the tear glands, causing tearing. Understanding the connection between food allergies and tearing is important for timely diagnosis and treatment of allergies, as well as for preventing serious complications.
Diseases
Tearing due to food allergies can be associated with various allergic reactions that cause inflammation and irritation of the mucous membranes. The most common diseases accompanying this symptom include allergies to certain foods such as nuts, dairy products, eggs, seafood, and wheat. When these allergens enter the human body, the immune system begins to react by producing antibodies and releasing histamines, which leads to inflammation, swelling, and, consequently, tearing.
It is also worth noting that tearing can be one of the signs of more serious conditions, such as anaphylaxis. This dangerous condition requires immediate medical attention and can be triggered by a sudden allergic reaction to food. Therefore, it is important to monitor the manifestation of food allergies and consult a specialist if symptoms other than ordinary tearing occur.
- Nut allergy
- Milk allergy
- Egg allergy
- Seafood allergy
- Wheat allergy
- Anaphylaxis
- Pollen sensitization (cross-reactions)
Diagnosis
The diagnosis of tearing due to food allergies begins with a thorough collection of the medical history and analysis of the patient’s symptoms. Doctors conduct an interview to find out which products may have caused a negative reaction, as well as studying the history of allergies in the family. This can help determine predisposition to certain allergic reactions and clarify possible triggers. It is important to note that allergy symptoms can vary in severity and can manifest both on the skin and from the respiratory system, which is also taken into account when making a diagnosis.
At the next stage, specific tests may be required to confirm the diagnosis. This usually includes skin tests to identify allergens or blood tests for specific IgE antibodies. In some cases, the examination may also involve provocation tests, which under medical supervision help determine how the body reacts to certain allergens. Correct diagnosis is important to avoid misunderstanding the causes of tearing and prescribe appropriate treatment.
- Skin tests for allergens
- Blood tests for specific IgE antibodies
- Provocation tests with food allergens
- Examination of the gastrointestinal tract (in case of suspicion of food allergy)
- Overall assessment of the patient’s health condition and comorbidities

Types of Eye Tear Production in Food Allergies
Tear production in food allergies can manifest in various forms and intensities, depending on individual characteristics of the body and the reaction to specific allergens. The severity of the symptom varies — from mild tearing that is barely noticeable to profuse tearing, leading to discomfort and difficulty in performing daily tasks. It is important to note that tearing is often accompanied by other allergic symptoms, such as itching, redness of the eyes, runny nose, and facial swelling.
There are several main types of tearing that should be considered. For example, it can be:
- Acute — occurs immediately after contact with the allergen and can last from several minutes to several hours.
- Chronic — can last for several days and requires medical diagnosis to identify and eliminate the cause.
- Paroxysmal — appears in episodes, for example, when consuming certain foods that cause allergies.
Causes of tearing during food allergy
Tearing during a food allergy is one of the common symptoms that occur in response to an allergen entering the body. When a person with an allergy consumes a product containing allergens, the immune system perceives them as a threat. This triggers the release of histamine and other chemicals, leading to inflammation and changes in the system responsible for tear production. As a result, the eyes start to tear up, which not only causes discomfort but can also indicate more serious allergic reactions in the body.
There are many reasons why tearing may occur during a food allergy. The most common include: individual intolerance to certain foods, genetic predisposition to allergies, and the presence of other allergic conditions such as rhinitis or asthma. Additionally, external factors such as stress and environmental pollution should be considered, as they can exacerbate allergy symptoms and lead to increased tearing.
- Reaction to dairy products
- Egg allergy
- nut sensitivity
- Shellfish intolerance
- Organic additives and colorants
Common Related Pathologies
Watery eyes due to food allergies are often accompanied by other diseases and conditions that can complicate the process of diagnosis and treatment. One of the most common related pathologies is allergic rhinitis, which manifests with symptoms such as a runny nose, sneezing, and itching in the nose. These symptoms can worsen upon consuming certain foods, making the management of food allergies especially challenging for patients.
Another common condition is eczema, which can present as redness, itching, and flaking of the skin, particularly in areas exposed to allergens. It is also worth mentioning anaphylaxis—a severe allergic reaction that can occur in response to consuming certain foods. In such cases, watery eyes may be just one of many manifestations, and to prevent serious consequences, patients need to seek medical help immediately.
- Allergic rhinitis
- Eczema
- Anaphylaxis
- Dermatitis
- Bronchial asthma
Expert Opinion
Lacrimation caused by an allergic reaction to certain food products is a common symptom that is often underestimated. Specialists note that such a reaction can be not only a sign of a general allergy but also a serious indicator of more severe diseases, such as atopic dermatitis or allergic rhinitis. It is important to remember that food intolerance can vary from mild manifestations to severe, life-threatening conditions such as anaphylactic shock.
Medical experts recommend carefully monitoring not only lacrimation but also other accompanying symptoms such as swelling, skin rashes, or difficulty breathing. If such manifestations are present, patients should consult an allergist for a comprehensive examination and accurate diagnosis. Conducting allergy tests and implementing an elimination diet will help determine exactly which foods trigger sensitivity.
Treatment of tearing due to food allergy
Treatment of tearing caused by food allergies includes both the elimination of the allergen and the reduction of inflammatory reactions in the body. The first step in therapy is to exclude from the diet foods that may trigger an allergic reaction. This can include common allergens such as dairy products, eggs, nuts, fish, and soy. It is important to carefully examine the composition of all products and avoid cross-contamination, especially if the patient has severe allergic reactions.
In addition to dietary changes, a doctor may recommend the use of antihistamines. These medications help reduce the level of histamine in the body, which decreases symptoms, including tearing. In cases of severe allergic reactions, stronger medications such as corticosteroids may be prescribed. However, their use must be strictly controlled and prescribed by a doctor. It is also important to consider the possibility of allergen vaccination, which can help reduce sensitivity to them in the future.
- Antihistamines (loratadine, cetirizine)
- Corticosteroids (prednisolone)
- Immunotherapy
- Nasal irrigation with saline
- Elimination of allergens from the diet
Complications
Teary eyes due to food allergy, although it seems like a minor symptom, can lead to a number of serious complications if not identified and addressed in a timely manner. First, constant tearing can cause irritation and inflammation of the eyes, which in turn can lead to more serious conditions such as conjunctivitis or keratitis. If a person continues to come into contact with the allergen, this may lead to the progression of the allergic reaction and an increase in its symptoms.
Second, continuous tearing can negatively affect the patient’s quality of life. This may lead to social isolation, decreased self-esteem, and other psycho-emotional disorders. Patients with persistent allergic manifestations may also face a lack of understanding of their condition in everyday life, which can become a source of additional stress.
Finally, in rare cases, during severe allergic reactions, more serious conditions such as anaphylaxis may develop, which requires immediate medical attention and can threaten the patient’s life. This underscores the importance of timely diagnosis and treatment.
- Conjunctivitis
- Keratitis
- Psycho-emotional disorders
- Increased allergic reactions
- Anaphylaxis
