This article will explain why some people experience allergic reactions to iodine-containing substances and how to manage the symptoms.
However, hypersensitivity reactions to fish and shellfish are likely because of the protein tropomyosin, not iodine.
However, these reactions are likely resulting from another component of the contrast.
Without iodine in our diets, our thyroid gland would not function and produce thyroid hormones.
These hormones are responsible for growth, brain development, bone formation, and energy metabolism.
Our bodies do not make iodine, and so we need to obtain it from our diets.
Treatment
An allergic reaction can be life-threatening and requires immediate medical treatment.
If you develop difficulty breathing, seek care right away.
If you could remember, tell your provider the exact symptoms you experienced and how long they lasted.
Often people with a history of allergic reactions are treated with medications to prevent a reaction before the procedure.
Iodine is naturally found in dairy products and seafood.
It is also added to other foods like table salt.
Misconceptions
Healthcare providers now believe that an iodine allergy is not because of iodine at all.
What was once thought to be an iodine allergy is most likely a hypersensitivity to a protein.
A shellfish allergy is believed to be because of a sensitivity to the protein tropomyosin.
Summary
Iodine is a vital nutrient that is needed for thyroid function.
It is unlikely for an individual to be allergic to iodine because the nutrient is needed to sustain life.
Allergies to shellfish are likely brought on by a hypersensitivity to the protein tropomyosin, rather than iodine.
An allergic reaction is a medical emergency and requires immediate treatment.
To better understand your risk, talk with your healthcare provider about any past allergic reactions.
Experts now know that there is not enough iodine in shellfish to elicit a reaction.
An allergist can test you for an iodine allergy using a skin patch test.
