A patient who has a high level of mast cell activity, dilation of blood vessels and acute drop in blood pressure is likely suffering from

" Anaphylactic shock immediately following exposure to allergen"

What is anaphylactic shock?

Anaphylaxis, also known as allergic or anaphylactic shock, is a severe, life-threatening allergic reaction that affects the entire body.

  • The reaction is characterized by restriction of the airways, which causes difficulties breathing.
  • In extreme situations, throat swelling might restrict the airway. Gastrointestinal symptoms such as severe stomach discomfort, vomiting, and diarrhoea are also possible.
  • Histamines, molecules produced by the body after an allergic reaction, cause blood vessels to dilate, resulting in a severe decrease in blood pressure.
  • Fluid can enter the lungs and cause swelling (pulmonary oedema).

Anaphylaxis is a medical emergency. The airway, respiration, and circulation should all be evaluated very away. CPR may be required.

Hence, the correct answer is option D
