Which of the following is a symptom of food allergies affecting the respiratory system?

Dyspnea, or difficulty breathing, is a symptom that can arise from food allergies affecting the respiratory system. This occurs when the immune system reacts to certain food allergens, causing inflammation and swelling in the airways, which leads to shortness of breath or a feeling of tightness in the chest. This symptom is particularly concerning as it can indicate a severe allergic reaction, potentially leading to anaphylaxis, which is a medical emergency requiring immediate attention.

In contrast, itching and hives are primarily skin-related symptoms that indicate an allergic response but do not directly pertain to respiratory symptoms. Colic is a term used to describe severe abdominal pain and is not associated with respiratory issues in the context of food allergies. Understanding these differences is crucial for recognizing the impact of allergens on various body systems and responding appropriately.
