Maybe: Each person has a 'set point' for their thyroid level and TSH is the best test to determine your set point because it is 10 times more sensitive than even free T3 (liothyronine) or free t4. Many people normally would have a TSH in the range of 0.4-1.0 and, if they have mild hypothyroidism and their TSH goes up to 2.3, they may have symptoms.

Undiagnosed hypoT?: Hypothyroidism can be primary - caused by a weak thyroid gland or secondary to other hormonal problems, like a pituitary problem. Or your thyroid can become dysfunctional secondary to high insulin, estrogen or cortisol. If you have functional hypothyroidism, this problem can go undetected by routine screening tests. More extensive testing can often reveal abonormalities. This is very common.
