In brief: Swelling & shock
When foods combine with ige antibodies attached to mast cells those cells release histamine & other potent biochemicals causing blood vessels to leak plasma into surrounding tissues resulting in swelling (edema).
If your eyelid swells its unsightly but no big deal. If your tongue or vocal cords swell you could die from suffocation. If enough plasma leaks out blood pressure falls leading to shock.
