Impact of Thyroid Hormones on Human Glucose and Energy Metabolism
The goal of this clinical trial to clarify the impact of changes in thyroid hormone levels on glucose and lipid metabolism.
Patients will be included in whom thyroid hormone levels are intentionally changed by treatment. In patients with Graves' disease, thyroid hormone levels will be lowered using medication, while in patients with thyroid cancer, thyroid hormone levels will be raised using medication. Oral glucose tolerance tests will be performed before treatment and at two time points after treatment begins to assess metabolic effects.
Inclusion: patients with initial diagnosis of graves disease OR; patients with initial diagnosis of thyroid carcinoma.
Exclusion: Diabetes mellitus; Current disease with activation of stress hormones; Acute infectious disease; contraindications for oral glucose tolerance test; Fasting glucose level ≥ 200 mg/dL; Exogenous insulin administration with action at the time of the test; Post-aggressive metabolism.
