Thyroid hormone changes may rewire your metabolism
NCT ID NCT07410637
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how changing thyroid hormone levels affect the way the body uses sugar and fat. Researchers will study people with Graves' disease (whose thyroid hormones are too high) and people with thyroid cancer (whose hormones are intentionally raised). Participants will take a glucose drink test before and after treatment to measure changes in insulin sensitivity and energy use.
