Episode - Risks of Iodine Contrast Agents and Thyroid Health


Risks of Iodine Contrast Agents and Thyroid Health

Iodine contrast media is used in several radiological procedures, such as CT scans.

With a typical dose of iodine contrast medium containing about 13,500 micrograms of free iodine, along with 15-60 grams of bound iodine that may be liberated as free iodine in the body, this represents an acute iodine load for the body.

From my research, contrast media seems to be a concern, especially for those with hyperthyroidism, although it could potentially affect those with hypothyroidism and Hashimoto’s.

Today I’m breaking down what five research studies show about the risk of contrast media for those with thyroid conditions and whether there are particular cases where it’s a bigger concern.


During this episode, you’ll learn what research shows about:

  • The amount of iodine in contrast medium far exceeds the minimum amounts which have been shown to cause iodine-induced hyperthyroidism
  • Potential for an increase in the risk of iodine contrast media-induced thyroid dysfunction
  • Cases where iodine contrast media can cause thyroid dysfunction in euthyroid nodule goiter patients
  • Rate of occurrence of iodine contrast media-induced thyroid dysfunction


As always, I hope you’ve found this episode valuable, and I look forward to catching you in the next episode!
