An anaphylactic reaction can lead to what serious condition?

An anaphylactic reaction can lead to a compromise of respiratory function due to the severe allergic response that it triggers. During such a reaction, the body releases a flood of chemicals, including histamines, which can lead to inflammation and swelling in the airways. This swelling can cause difficulty in breathing, characterized by symptoms such as wheezing, shortness of breath, and in more severe cases, complete airway obstruction. Furthermore, anaphylaxis can also cause bronchoconstriction, which further impairs the ability to breathe effectively.

While other options describe potential physiological changes, they do not accurately reflect the life-threatening consequences that commonly arise from anaphylactic reactions. The primary and most dangerous effects often center on the respiratory system, highlighting the critical need for immediate medical intervention in suspected cases of anaphylaxis.
