What Causes Seafood Allergies?
Seafood allergies are caused by the body’s immune system mistakenly identifying proteins in seafood as harmful. When this happens, the immune system produces antibodies called immunoglobulin E (IgE). These antibodies bind to cells in the body called mast cells, which then release histamine and other chemicals that cause allergic symptoms.
How to Manage Seafood Allergy
There is no cure for seafood allergy, but it can be managed by avoiding seafood. People with seafood allergy should also carry an epinephrine auto-injector (EpiPen) in case of an allergic reaction. Epinephrine is a medication that can quickly reverse the symptoms of anaphylaxis.
Other Tips for Managing Seafood Allergy
- Read food labels carefully to avoid hidden seafood ingredients.
- Ask about seafood when eating out at restaurants.
- Wear a medical ID bracelet or necklace that states your seafood allergy.
- Talk to your doctor about how to manage your seafood allergy.
Conclusion
Seafood allergies can be a serious health condition, but they can be managed by avoiding seafood and carrying an epinephrine auto-injector. If you think you may be allergic to seafood, talk to your doctor to get tested.
