Being allergic to something can cause discomfort, irritation, and in severe cases, life-threatening reactions. In the English language, there are various synonyms that can be employed to describe the same condition. Some of the commonly used synonyms for "were allergic to" include hypersensitive, intolerant, susceptible, adverse, sensitive, and intolerable. Individuals who have a hypersensitive immune system may exhibit symptoms such as itching, sneezing, wheezing, or hives when they come into contact with allergens. People who are intolerant to certain foods or substances may encounter difficulties such as nausea, vomiting, or diarrhea. It's essential to identify and avoid allergens to prevent adverse reactions.
