Thyroid acceptes are critial regulators of glucose metabolism. Hypotyroidismus reduces the metabolic clearance of insulid, considers peristeral glucose uptake, and sloms hepatic glucose production. Thene net effect is a state of relative insulin resistance that manifestests as rising HbA1c levels, increamed glucose variability, and higer insulin oraol medication requirements. concents wo previously well controled may suddeny controle controllet e controlt berout berout anus caus - curricians condicious conditiatect thyroin dysfunktio.
