Question

Which of the following is the symptom of anaphylactic shock?

• A. Low blood pressure
• B. High blood pressure
• C. Vomiting
• D. Both A and C

Answer 1

The correct option is D Both A and C

Anaphylaxis is a type of severe allergic reaction which can result in the death of the person. The immune cells on an encounter with the allergen release many cytokines which are responsible for the allergic symptoms. The binding of the histamine to H${}_1$ receptors causes an increase in the diameter of the blood vessels which causes decrease in the blood pressure. There is production of more acid in the stomach which causes vomiting.

Thus, the correct answer is option D.
