Shellfish allergy can develop at any age. Even people who have eaten shellfish in the past can develop an allergy. Some people outgrow certain food allergies over time, but those with shellfish allergies usually have the allergy for the rest of their lives. When someone is allergic to shellfish, the body's immune system , which normally fights infections, overreacts to proteins in the shellfish. Every time the person eats or, in some cases, handles or breathes in shellfish, the body thinks these proteins are harmful invaders and releases chemicals like histamine.
This can cause symptoms such as:. Allergic reactions to shellfish can differ. Sometimes the same person can react differently at different times. Some reactions can be very mild and involve only one system of the body, like hives on the skin. Other reactions can be more severe and involve more than one part of the body. Shellfish allergy can cause a severe reaction called anaphylaxis , even if a previous reaction was mild.
Anaphylaxis might start with some of the same symptoms as a less severe reaction, but can quickly get worse. The person may have trouble breathing or pass out. More than one part of the body might be involved. If it isn't treated, anaphylaxis can be life-threatening. If you have a shellfish allergy or any kind of serious food allergy , the doctor will want you to carry an epinephrine auto-injector in case of an emergency.
An epinephrine auto-injector is a prescription medicine that comes in a small, easy-to-carry container. It's easy to use. Get creative with other protein options like tofu, beans, lentils, chicken, eggs, lean meats and nuts to replace the seafood you are allergic to. Carefully reading the ingredient list of food products every time is important to avoid an allergic reaction.
