My TSH is around 3. Fatigue, low energy. Have PCOS and insulin resistance. Can I be suffering from hypothyroidism? Is there a link with metformin?

5 doctors agree

In brief: Thyroid

Most US laboratories will report a TSH of 3 as "normal," but most endocrinologists in 2014 consider normal or be under "roughly" 2.
5 (dissenting opinions welcome.) It's so close you might get different opinions from different doctors whether this makes you hypothyroid or not, but it's a close call either way. There is no association between metformin and thyroid function.
