In brief: Life-threatening rxn
Anaphylaxis is a life-threatening allergic reaction affecting several parts of the part simultaneously.
Mast cells release histamine & other substances making blood vessels leaky. The plasma leaking out causes swelling in the skin (hives & angioedema) & windpipe (laryngospasm) as well as asthma, vomiting, gut pain. If enough plasma leaks out the patient may go into shock. Death may ensue.
