What are common symptoms of a shellfish allergy?

A shellfish allergy can trigger a range of symptoms that are linked to an immune response to proteins found in shellfish. The most common symptoms include hives, which are raised, itchy welts on the skin, and swelling that can occur in various parts of the body, particularly in the face, throat, or mouth. These symptoms can escalate quickly and may lead to difficulty breathing due to swelling of the airways, which is a serious condition requiring immediate medical attention. Gastrointestinal distress, such as nausea, vomiting, or abdominal pain, is also typical after consuming shellfish for those with this allergy.

This combination of symptoms—ranging from skin reactions to respiratory issues and gastrointestinal problems—is characteristic of a more severe allergic reaction known as anaphylaxis, which can occur in some individuals. Therefore, recognizing the signs associated with a shellfish allergy is crucial for timely intervention and management.
