Plasma levels of resistin and ghrelin before and after treatment in patients with hyperthyroidism.

Objective: To investigate ghrelin and resistin concentrations in patients with hyperthyroidism before and after restoration to a euthyroid state and to correlate the 2 peptides with anthropometric and insulin resistance parameters.

Methods: The study included hyperthyroid patients and euthyroid healthy participants as a control group. Hyperthyroid patients were evaluated at the start of the study and after normalization of thyroid function with appropriate antithyroid drugs.
