help with tsh
I have had weird health issues for a while. I started seeing a new doctor due to hairthinning all over my body and she did alot of blood work and said my TSH was low at 0.23. The normal range started at 0.45. I had it ran with another doctor in the morning about 2 weeks later and it was normal at 0.44. I didn't ask what the normal range started at. Is it normal for it to do this or could this be causing me symptoms.
TSH itself causes no symptoms. TSH is a pituitary hormone that is a messenger to the thyroid glands to produce thyroid hormone. At best TSH is an indicator, to be considered along with more important indicators, such as symptoms, and also the levels of the biologically active thyroid hormones, free T3 and free T4 (not the same as total T3 and total T4). FT3 is the most important because it largely regulates metabolism and many other body functions. Scientific studies have also shown that FT3 correlated best with symptoms, while FT4 and TSH did not correlate.
What other symptoms do you have besides hair thinning? Have thyroid tests other than TSH been done for you? If so, please post results and reference ranges, so that members can help interpret and advise further. If not, then you are going to need additional testing done, dependent on the answers to these questions.

Hi Nikkie, I just answered someone else about what the normal TSH level is. Here is what I wrote - hope it helps:
Ideally, your TSH should be between .3 and 3.0 according to the "new range" guidelines suggested by the American Association of Clinical Endocrinologists in 2002/3 or you risk a myriad of side effects and complications.
For me personally, I feel best when my TSH is between 1 and 2. Both over and under active thyroid function have their fair share of dangers. It can be tough to find a doctor who will listen to your concerns rather than going only by your lab results. Persevere - it's YOUR health on the line.
I encourage you to read through Mary Shomon's website all about the thyroid. You will find just about every question and answer you could think of there: http://thyroid.about.com
Good luck!
