Shellfish Allergy

Shellfish allergy is a common food allergy that occurs when the immune system mistakenly identifies proteins in shellfish—like shrimp, crab, and lobster—as harmful. This reaction can lead to symptoms such as hives, swelling, stomach cramps, or even severe reactions like anaphylaxis, which requires immediate medical attention. Shellfish allergies often develop in adulthood and can be lifelong. It's crucial for individuals with this allergy to avoid shellfish entirely and to read food labels carefully, as shellfish can be present in unexpected dishes. Consulting with an allergist can help manage and understand this allergy better.
