Low-Iodine Diet's impact on thyroid cancer treatment measured in new study
NCT ID NCT05599139
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how a 7-day low-iodine diet changes the amount of radioactive iodine taken up by the body in people who have had their thyroid removed due to thyroid cancer. Researchers will measure iodine uptake before and after the diet in 25 adults. The goal is to understand if the diet improves the effectiveness of a common follow-up treatment.
