What commonly results from anaphylaxis if not treated promptly?

Anaphylaxis is a severe, life-threatening allergic reaction that requires immediate medical intervention. If not treated quickly, anaphylaxis can lead to significant physiological changes in the body, including airway constriction, severe drops in blood pressure, and cardiovascular collapse. These changes can progress rapidly, resulting in cardiac arrest or even death. The critical aspect of anaphylaxis is its rapid onset and potential to escalate quickly, making prompt treatment with epinephrine essential to stabilize the individual and prevent these severe outcomes.

In contrast, other options such as mild allergic reactions, chronic respiratory issues, or skin infections do not accurately represent the dire consequences of untreated anaphylaxis. While individuals may experience various allergic reactions, mild ones are not a result of severe anaphylaxis. Chronic respiratory issues could develop from repeated exposures but are not the immediate consequence of anaphylaxis. Skin infections are unrelated to anaphylaxis and its acute dangers.
