In suspected anaphylaxis, which symptom is categorized as GI involvement?

• A. Throat tightness
• B. Dizziness
• C. Nausea
• D. Cough

Answer: (C)

GI involvement in anaphylaxis refers to symptoms arising from the digestive tract, such as nausea, vomiting, abdominal cramping, or diarrhea. Nausea fits this category because it reflects smooth muscle and GI tract mediators activated during an allergic reaction. The other options point to airway or circulatory issues—throat tightness signals airway edema and potential obstruction, dizziness often comes from reduced blood pressure, and cough relates to bronchospasm or irritation of the respiratory tract. So nausea is the symptom that demonstrates GI involvement.
