Iodine Allergy Symptoms

Effects of allergic reaction to allergy are noticed in various symptoms and their severity varies from one person to another, according to the capacity of the body to fight against the allergens. Following are some of the signs of iodine allergy:

• If you are allergic to iodine and you consume food that contain iodine, you may experience vomiting and nausea. But, allergic to certain foods may also trigger these symptoms. Hence, it is good to consult a physician who suggests some tests for determining the allergy.
• You may also experience external symptoms such as hives, itching and skin rashes. Irritation in the nose, watery or red eyes or runny nose can also be noticed in this allergic reaction.
• Swelling in throat can also be a symptom of iodine allergy. This symptom can trigger breathing problems. This is triggered because of the obstruction in airways and is a life threatening symptom. Anaphylactic shock or asthma attack can be other serious symptoms of allergy that need medical attention immediately. Increase in heartbeat, tightness in throat and difficulty in breathing are some of the anaphylactic shock symptoms. Make a point that anaphylactic shock may also result in death of a person if left untreated.
• If you have any thyroid problem, it may not produce sufficient hormones. In this case, you may not be given supplements of iodine. It can cause health problems such as obesity, weakness and mental health problems as well.
• Iodine allergy symptoms can also include certain conditions such as fatigue and lightheadedness, dizziness, flushes, diarrhea, coughing, drop in blood pressure, rapid pulse and fever.

    What is Iodine allergy? posted 6/13/09
    No relation between iodine, shellfish/fish, topical iodine preparations, and x-ray dye. Iodine from an allergic standpoint is literally inert. Iodine compounds are naturally found in our bodies, and in the food we eat, including table salt. When’s the last time someone had an allergy to table salt?? Or, when was the last time someone with an iodine allergy was told by his doctor not to use table salt or eat spinach (also rich in iodine)? In x-ray contrast and topical iodine antiseptics, its other chemicals in the preparation which can causes reactions. In shellfish, its the protein within it that causes those allergic reactions.
    Please refer to the Society for Diagnostic Imaging’s article on the Iodine Myth.
