What causes localized anaphylaxis?
This is usually in response to ingested or inhaled allergens – presents as itchy eyes, sneezing, etc…..
Localized anaphylaxis is typically caused by exposure to an allergen. When an allergen comes into contact with the body, it triggers an immune response that causes the release of histamine and other chemicals that lead to swelling, itching, and other symptoms.
In localized anaphylaxis, the reaction is usually limited to the area of the body that came into contact with the allergen. For example, if a person is allergic to a particular type of plant, exposure to that plant may cause a localized reaction on their skin where it came into contact. Insect stings or bites can also cause localized anaphylaxis.
Other factors that may contribute to localized anaphylaxis include genetics, environmental factors, and lifestyle factors. For example, people who have a family history of allergies or asthma may be more likely to develop localized anaphylaxis after exposure to an allergen. Similarly, exposure to certain pollutants, such as cigarette smoke, may make individuals more susceptible to allergen sensitization and the development of localized anaphylaxis.
