An allergic reaction (/əˈlɜːrdʒɪk riˈækʃən/) (noun) is a common health issue where the body’s immune system overreacts to a harmless substance called an allergen. This vocabulary term is relevant to the IELTS exam, especially in the Listening and Reading sections, where health-related topics are frequently discussed.
Here are some synonyms and related terms:
- Hypersensitivity (noun) /ˌhaɪpərˌsɛnsɪˈtɪvɪti/: This term refers to an exaggerated immune response to a substance. Example: The patient exhibited hypersensitivity to pollen, leading to severe allergic reactions.

- Anaphylaxis (noun) /ˌænəfɪˈlæksɪs/: A severe, potentially life-threatening allergic reaction. Example: The child went into anaphylaxis after being stung by a bee.
- Intolerance (noun) /ɪnˈtɒlərəns/: This term describes difficulty digesting a certain food, often with unpleasant symptoms, but it’s not an immune response like an allergy. Example: Lactose intolerance is a common digestive issue.
