Shellfish Allergy: Medical Alert And Awareness

By Tonci Vulin


Throughout the US, any adults are experiencing allergies that are brought about eating shellfish. Figures show that 0.1% of the population are children having shellfish allergy and over 2% of the overall US population are adults with shellfish allergy.

It is during adulthood that shellfish allergies are likely to develop. Persons with shellfish allergies are likely to have lifelong food allergies.

What are the Typical Signs and Symptoms of Shellfish Allergy Just a few minutes or few hours after eating shellfish, symptoms may then be noticed. The following are the signs and symptoms of shellfish allergy: Hives and eczema are some of the typical skin allergic reactions. Group of reactions like watering of eyes, itchiness and redness is known as allergic conjunctivitis. GI reactions like nausea, abdominal pain, vomiting, or diarrhea. Wheezing, runny nose and coughing are also respiratory symptoms that are brought on by allergy.

Your lips will swell as well as your tongue and face. These symptoms are called angioedema. Shellfish allergies may cause a serious reaction known as anaphylaxis. Anaphylaxis is a medical emergency that requires instant medical attention. Shellfish allergy is the most common causes of Exercise-Induced Anaphylaxis, in which the combination of eating a food allergen and working out brings about anaphylaxis. What's with Shellfish that Causes Allergies

Mollusks and Crustaceans are two main families of the shellfish origin. Mollusks contain clams, oysters, and squid. While lobsters, shrimps and crayfish are under the family of crustaceans. Shellfish can live both on land and water (fresh or salt).

Individuals who are allergic to one form of crustacean, like shrimp, are generally allergic to all other crustaceans. If you are allergic to crustaceans, you may or may not be able to eat mollusks such as clams or oysters. You can still eat shellfish so long as you have undergone an allergy screening.

The allergenic protein in shellfish (tropomyosin) isn't only found in sea creatures. People with shellfish allergies may also have reactions to land snails, dust mites, cockroaches, or other insects.

Coping With a Shellfish Allergy You must avoid shellfish or make preparations just before allergic reactions since there is no known treatment for shellfish allergy to date. If you have been diagnosed with a severe shellfish allergy, your doctor will recommend an epinephrine auto-injector (commonly called an Epi-Pen) that you will need to carry with you all the time. Remember that food allergens can be contained in almost all food items. You will have to learn to read labels to avoid shellfish, and learn to ask questions when you eat in eating places. Shellfish and Labeling Laws: The Food Allergy Labeling Law (FALCPA) identifies crustacean shellfish as one of the huge eight allergens, but not mollusks. This signifies that manufacturers are not forced to list the existence of clams, oysters, mussels, scallops or other mollusks in ingredient lists.

Mollusks have wide variety of shellfish types so if you are allergic to crustacean shellfish, its apt to be allergic to other kinds. You can determine the safety of eating mollusks by having an allergy tests.

For those who have known shellfish allergies, its best to read the content and label of the items you are purchasing. Shellfish Allergy and Iodine There are unverified issues of a cross reactivity between shellfish allergy and iodine/contrast allergy - some old medical forms still list this inaccurately as a contraindication. Radiocontrast components are iodine-containing products and they don't need to be averted when you have shellfish allergy. It is possible to be allergic to iodine or radiocontrast material, but those allergies aren't linked to shellfish allergies, so you do not need to fret about cross-reactions.

Signs and Symptoms of Shellfish Poisoning Shellfish poisoning is also known as Red Tide and Paralytic Shellfish Poisoning. You might mistake yourself with the symptoms of shellfish poisoning for an allergic reaction because it normally erupts within 30 minutes after ingestion of spoiled shellfish. Saxitoxin is a potent toxin that largely triggers shellfish poisoning. This toxin is unveiled by algae organisms located in the molluscs, clams and oysters. Mollusks are the ones that contain the toxin and not the lobsters and fishes. Prickling or burning sensation in the mouth or extremities, nausea, vomiting, and diarrhea are the frequent allergic symptoms of this shellfish poisoning. Shellfish poisoning is something that should not be neglected as this could lead to life-threatening circumstances. You must seek instant medical care if you are experiencing these symptoms.
