Step-by-step explanation:
Wheezing or shortness of breath, and swelling of the face, hands, or feet are signs that a person is having an allergic reaction to certain foods. Allergies are a hypersensitivity of the immune system to typically harmless substances in the environment, such as certain foods. When a person with food allergies consumes these foods, their immune system reacts, leading to symptoms like difficulty breathing, swelling, and wheezing. These symptoms can be life-threatening and require immediate medical attention.
