Why am I suddenly allergic to seafood?
Shellfish allergies are most often the immune system’s response to a protein found in shellfish muscles called tropomyosin. Antibodies trigger the release of chemicals such as histamines to attack the tropomyosin. The histamine release leads to a number of symptoms that can range from mild to life-threatening.
How long does a fish allergy last?
Symptoms usually start as soon as a few minutes after eating a food and as long as two hours after. In some cases, after the first symptoms go away, a second wave of symptoms comes back one to four hours later (or sometimes even longer). This second wave is called a biphasic reaction.
