Fish and Seafood Allergy

One bite of salmon, a forkful of shrimp, a trace of tuna in a sauce — and your system switches into alarm mode. Your lips swell, your tongue tingles, your skin begins to burn, your throat tightens. In more severe reactions, your circulation can collapse, your breathing falter, your consciousness fade. Fish and seafood allergy is among the most dangerous food allergies of all — with a real risk of anaphylactic shock.

Medically, this can be explained: proteins in fish flesh, tropomyosin in crustaceans, parvalbumins in certain fish species — your immune system identifies them as enemies and launches an excessive defensive response. That is the physical level. And it is real. It is serious. It deserves the respect that emergency medicine and allergy care extend to it.
