When a person with a seafood allergy consumes seafood, their immune system produces an antibody called immunoglobulin E (IgE) in response to the proteins found in the seafood. This triggers the release of histamine and other chemicals in the body, leading to allergy symptoms such as itching, hives, swelling, and difficulty breathing.

It is important to note that the specific compounds that cause seafood allergies can vary from person to person, and some individuals may be allergic to more than one type of seafood. If you suspect that you may have a seafood allergy, it is important to consult with a healthcare professional for diagnosis and treatment. Severe allergic reactions can be life-threatening, so it is important to take allergies seriously and take steps to avoid exposure to the allergen.
