because shells have some greams in them
They have no shell but yes they are technically shellfish. If you have a shellfish allergy you can't eat octopus.
Yes, an octopus is a shellfish. It is also a mollusk which is a shellfish.
yes
If one is allergic to shellfish, they are cleared to eat all regular fish. However, they should take care with eating sushi or other fishes, as there is sometimes shellfish residue.
Not necessarily. Shellfish allergies often come in different categories, like crustacean (shrimp, crab, lobster, etc.) or mollusk (clams, oyster, squid, etc.). While most people who have shellfish allergies are allergic to all shellfish, that is not always the case. An allergist can administer a test to determine what type(s) of shellfish allergy you may have.
Yes.
They didn't allow me to proceed with my barium swallow. They said that people who are allergic to dyes, iodine, or shellfish may also be allergic to barium so to be safe they didn't let me do it.
Isovue should not be used if a person is allergic to shellfish or iodine. Isovue is usually administered by vein and is a dye used in x-raying.
The reason why shellfish allergy is asked is because of the link between shellfish allergy and iodine allergy (shellfish are rich in iodine). That does not mean that if your allergic to shellfish then you are allergic to iodine - you may be allergic to another component that is in the shellfish. Iodine is used in the thyroid scan as a dye and is injected into your veins. If you are allergic then the reaction would be quite quick and potentially serious. Asking about a shellfish allergy is to try to risk stratify those that may be more susceptible for a reaction and "prepare" the technician / radiologist for the worse case scenario. The main allergic reaction we would be worried about would be true anaphylaxis (if you've not heard of this then you probably not had it). Rashes and facial swelling would indicate a allergic reaction. Sickness, diarrhea and feeling "off" would suggest an intolerance rather than a true allergic reaction. Happy New Year! El Tango
