Re: Yeah, Normal TSH!!
That tsh is NOT normal, and the nurse needs to get more educated. Do a search for new AACE tsh guidelines. A tsh that high is considered hypo even by the American Association of Clinical Endocrinology. Unfortunately, most labs have not changed their reference ranges even though these guidelines were issued about 3 years ago. Anything above 3.04 is considered hypo, and these guidelines were made after a study that indicated that >95% of carefully screened people without any symptoms of thyroid disease had a tsh under 2.5. Most healthy people have tsh closer to 1.0.
If you do not have ANY symptoms of hypo, then maybe it is ok for you to be at that tsh level, but if you do have symptoms, you would need an increase in meds. How are your free t4 and free t3 levels?
Over time, changes in your body (for example, menopause), stress level, and even weather changes could affect your medication dosage. It is common for people to go up in their dosage and sometimes down.
