Yes, metformin can affect the thyroid, primarily by lowering Thyroid-Stimulating Hormone (TSH) levels, especially in people with existing hypothyroidism or subclinical hypothyroidism, while generally having no significant effect on TSH in people with normal thyroid function (euthyroid individuals). This TSH reduction can be beneficial (helping manage hypothyroidism or even shrinking thyroid nodules) but also complicates monitoring, as it can mimic hyperthyroidism or interfere with levothyroxine dosing. 

Why take levothyroxine on an empty stomach?
