What are common symptoms associated with an allergic reaction?

Common symptoms associated with an allergic reaction include rash, swelling, itching, and shortness of breath. When the body encounters an allergen, such as pollen, pet dander, or certain foods, the immune system reacts by releasing histamines and other chemicals that lead to these symptoms.

Rashes or hives typically appear as a result of the skin's reaction, causing redness and itching. Swelling can occur in various parts of the body depending on the type of allergen and individual response, commonly seen in the face, throat, or around eyes. Shortness of breath is a serious symptom that may occur if the airways become constricted, leading to difficulty breathing, which can be a sign of a more severe allergic reaction, such as anaphylaxis.

Thus, the combination of these symptoms highlights the potential severity and variety of responses an individual may have to allergens, making this choice the most accurate representation of an allergic reaction.
