Food allergy: symptoms, diagnosis, and treatment approaches

Basics of food allergies

Food allergy is an immunological reaction of the body to certain food components, resulting in various symptoms. The clinical picture of food allergy can vary from mild dermatitis to severe symptoms, including anaphylactic shock. The mechanism of food allergy development is linked to the involvement of the immune system and the body’s ability to adequately respond to introduced food antigens.

Development of food allergy

The reasons for the development of food allergies can be diverse and may include genetic factors, immune system disorders, as well as environmental influences. Genetic predisposition plays an important role in the occurrence of allergic reactions to certain foods. Some people may have a family history of allergies, which increases the likelihood of developing food allergies in themselves or their offspring. Furthermore, changes in the environment, including the use of pesticides, hormonal additives, and food processing methods, may also contribute to the rise in food allergy cases.

  • Genetic predisposition: Hereditary factors play a key role in the development of food allergies.
  • Immune system: Disorders in the immune system can lead to allergic reactions to certain foods.
  • Environmental factors: Pesticides, hormonal additives, and food processing methods can increase the risk of developing food allergies.
  • Early introduction of new foods: Late introduction of foods in childhood may contribute to the development of allergies.
  • Systematic consumption of allergens: Constant exposure to allergens can trigger the development of food allergies.

Main symptoms of food allergies

The main symptoms of food allergies can manifest in various ways and include skin manifestations, respiratory problems, as well as gastrointestinal disorders. Skin reactions, such as itching, hives, or facial swelling, may be the first signs of an allergy to certain foods. Respiratory symptoms, such as a runny nose, throat itching, coughing, or shortness of breath, can also indicate the presence of an allergic reaction to food. Various gastrointestinal disorders, including nausea, vomiting, diarrhea, or abdominal pain, can also be observed in people with food allergies.

  • Skin manifestations: One of the most common symptoms of food allergy is itching, red rashes, and swelling on the skin, also known as urticaria.
  • Respiratory problems: Food allergy can cause various reactions in the respiratory system, such as runny nose, difficulty breathing, coughing, or sneezing.
  • GI disorders: Allergic reactions to certain foods can be accompanied by symptoms in the gastrointestinal tract, such as nausea, vomiting, diarrhea, or abdominal pain.
  • Anaphylactic shock: In the case of a severe allergic reaction to food, anaphylactic shock can occur, characterized by a sharp drop in blood pressure, swelling, and difficulty breathing.
  • Atopic dermatitis: In some individuals, food allergies may lead to the development of atopic dermatitis, characterized by dry, itchy skin and rashes.

Approaches to the treatment of food allergies from the experts’ perspective

Experts in the field of allergology emphasize a comprehensive approach to the treatment of food allergies, which includes avoiding the allergen, educating the patient on managing reactions, and medication therapy when necessary. Avoiding contact with foods that trigger allergic reactions is the primary step in treating food allergies and can significantly reduce the likelihood of symptoms occurring.

Experts also recommend developing an individualized action plan for each specific patient with a food allergy, including clear instructions on what to do in case of an allergic reaction and having prescriptions for necessary medications for quick assistance. This approach helps manage risks and ensures the safety of the patient in case of an emergency.

Methods for diagnosing food allergies

Diagnosis of food allergy requires a comprehensive approach and may include various methods, including the patient’s medical history, physical examination, as well as laboratory and instrumental studies. The doctor may ask questions related to diet, reactions to certain products, and also conduct a physical examination to identify possible signs of allergy. To clarify the diagnosis and determine the specific allergen, laboratory tests such as blood tests for antibody levels, skin tests, or food provocation tests under medical supervision may be used.

  • Medical history and examination: The doctor conducts a detailed study of the patient’s medical history, including diet and reactions to certain foods, as well as performs a physical examination to identify possible signs of allergy.
  • Laboratory tests: Blood tests for IgE antibody levels can help determine an allergic reaction to specific allergens. Other tests include tissue reactivity (soluble induced plasma), which can help identify specific allergens in the body.
  • Skin allergy tests: Skin tests may be used to identify possible allergic reactions to certain foods by applying small amounts of allergens to the skin.
  • Food provocation tests: In some cases, special tests are conducted where the patient is given small doses of the suspected allergen under medical supervision to observe for an allergic reaction.
  • Instrumental studies: In some cases, instrumental studies such as X-rays or endoscopy may be used to identify changes related to food allergies in the respiratory and digestive organs.

Methods of treating food allergies

The treatment of food allergies depends on the severity of the symptoms and the type of allergy in the patient. The main goal of treatment is to prevent contact with allergens and reduce the risk of allergic reactions. In cases of food allergies, eliminating the offending foods from the diet is a key step in treatment. For moderate to severe forms of food allergies, the prescription of antihistamines, glucocorticoids, or epinephrine may be required to alleviate acute allergic reactions. In the case of confirmed food allergies, it is important to discuss an individual treatment plan and precautions with a doctor to minimize the risk of serious complications.

  • Exclusion of allergens from the diet: An effective method for treating food allergies is the exclusion of allergens from the patient’s diet.
  • Pharmacological therapy: In some cases, prescribing antihistamines, glucocorticosteroids, or epinephrine may help in treating acute allergic reactions.
  • Immunotherapy: Immunotherapy, or allergen-specific immunotherapy, can be used for patients with severe forms of allergy to certain food allergens.
  • Diet adherence: An important aspect of treating food allergies is adhering to a special diet that excludes allergens and provides the patient with complete and safe nutrition.
  • Patient education: It is important for patients with food allergies to receive education on self-help, including the ability to recognize the symptoms of an allergic reaction and respond appropriately if necessary.

Measures to prevent food allergies

Prevention of food allergies plays a key role in preventing the occurrence of allergic reactions in susceptible individuals. Important preventive measures include consulting a specialist to identify possible allergens, strictly adhering to a diet, and avoiding contact with known allergens. For those at increased risk of developing allergies, special attention is given to food safety issues and effective training to prevent allergic reactions. Early detection of allergies and taking appropriate measures can significantly reduce the risk of serious complications and provide a better quality of life for patients with food allergies.

  • Consultation with a specialist: It is important to consult with an allergist or immunologist to identify potential allergens and determine a prevention strategy.
  • Diet compliance: Avoiding potentially harmful products and maintaining a safe diet helps prevent allergic reactions.
  • Avoiding contact with allergens: Individual protection against allergens such as pollen, mold, animals, or food products helps reduce the risk of allergies.
  • Food safety: Paying attention to the quality, origin, and processing of food products helps prevent food allergies.
  • Allergy prevention education: Conducting educational programs for patients and parents on activities to prevent allergic reactions and the proper response in case of an allergy plays a key role in prevention.

Amazing facts about food allergies

Food allergies can manifest in various forms and on the most unexpected products, including those that are usually not considered allergens. For example, an allergy to fruits or vegetables can occur even in those who typically do not experience allergic reactions. Another interesting fact is that some people may exhibit an allergic reaction not to the product itself, but to the smell or vapors of that product, which makes diagnosis challenging and requires special attention when studying allergic reactions.
