Thanks for your comment! I find it very disappointing when doctors don't test or suggest what to test for. In my case my husband doesn't care, but I want to feel the same like I used to be. I'll be 40 next month, I don't want to feel like my life is over. Many women don't pursue testosterone because don't know, and if the doctors don't mention testosterone as a test, that's the end of it.
I expect that your low TSH has resulted in low FT4 and FT3, but that needs to be confirmed. In addition you need to be tested for Vitamin D, which is very important, B12 and you were tested for ferritin, which needs to be 100, so yours is terribly low.Low ferritin (iron) can also cause symptoms, some of which mimic hypothyroidism.
Even more important than test results, it is vital to know about your symptoms.
Does anyone have this problem? The doctors said my thyroid is low and I'm going to get it tested again to see if its still low or not. Will this cause problems in my pregnancy?
My latest labs show low TSH and "low thyroid" (according to the nurse) Am now waiting for the
scan in 3 more weeks. What is the Dr. looking for?
80) TSH had been as high as 13 in the past and as low as 1.497. Upon retest, two months later, my TSH was too low (.023) so my does was cut in half. Upon retest, 6 weeks later, my TSH was even lower (.005). Doctor took me off my meds and scheduled me for a thyroid scan and uptake and new bloodwork (still waiting on the scan results). My TSH is now .246 off meds completely for 8 weeks. However, my free T3 is now 2.17 (2.30-4.20 pg/mL) and my T4 is now 0.90 (0.70-1.80 ng/dL).
I got a call from my doctor today. I've been told, I have low thyroid and I would have to come into my GP's office.
Is there some reason I need to see the Doctor AGAIN. Can't this medication just be phoned into the Rx? Should
I get a referral to a specialist?
Typically, when there are plenty of thyroid hormones, TSH remains low, because the thyroid does not need further stimulation. If TSH goes too low, as in your case, this is an indication that the thyroid is producing too much of thyroid hormones. This is called hyperthyroidism and "can" be a very serious situation.
You should call your doctor back and tell her/him how you are feeling. You need treatment as soon as possible.
If not on thyroid medication then you need additional testing to determine cause of the low TSH. If taking thyroid medication, that frequently will result in a suppressed TSH and is the basis for the following comments.
When taking thyroid medication, a suppressed TSH does not automatically mean that you are hyper, unless you are experiencing hyper symptoms that are a result of excessive levels of the biologically active thyroid hormones, Free T3 and Free T4.
The pituitary turns down the thermostat (lowers the TSH levels) when the thyroid is more active and thyroid hormones are abundant in circulation, and it turns up the thermostat (increases TSH levels) when circulating thyroid hormone is diminished and the thyroid is sluggish and needs stimulation. Of course, if there is something wrong with the pituitary gland, that could potentially depress the TSH level.
Was that Thyroglobulin or Thyroglobulin Antibodies? If she didn't order the Thyroglobulin Antibodies, she needs to do, as well as the Thyroid Stimulating Antibodies.
Thyroid Peroxidase is hardly ever run as a test, either; it's almost always Thyroid Peroxidase Antibodies. Thyroid Peroxidase is used in the production thyroid hormones. Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TgAb) are used to diagnose Hashimoto's Thyroiditis.
Per goolarra's questions - we need to know whether you have been diagnosed with a thyroid condition and/or are taking any type of thyroid medication.
Exactly how low is your TSH? As goolarra said, TSH can fluctuate wildly, even intraday, so having it drop over the course of a year, is not surprising.
We also need to know what other thyroid tests have been done and what those results and reference ranges are.
The TSH is low, suggesting too much thyroid medication - usually this would result in a dose decrease - unless you have a history of thyroid cancer that requires the TSH to be suppressed to < 0.1.
TSH is Thyroid Stimulating Hormone. This number changes in inverse to the amount of Thyroid hormone in your system, so a low TSH level would mean that you have increased levels of Thyroid Hormone.
TSH has a pretty broad range, so it is best if you have a history of blood levels so that you can see what has been normal for you in the past. A lower TSH could be normal for you.
