I had my thyroid removed in 1999. How can I have normal levels?

[Cathyhvt]

Removal in 1999, have been unmedicated for last 6 years. Why would my tests say my levels are normal?

You really need to know the actual tests, results, and reference ranges shown on the lab report.   When you have those, please post here and we will be happy to help interpret results and advise further.

So you were on Synthroid for 6 years after the thyroidectomy, correct?  Then you had a blood test and levels were normal and you have not taken any thyroid med since?  

More important than blood tests, what symptoms do you have, if any?  

[Cathyhvt]

Was on Synthroid for 13, off now for the last 6 years.  Symptoms are what you would expect... extreme fatigue, weight gain of 40-50 lbs. Went to emergency care for back strain and doctor offered to take blood while I was there.

Thyroid gland tissue can regenerate interestingly enough.

After 19 years? ????????

[Red_Star]

Yes. One woman had a fully regrown thyroid gland 40 years later!

[gimel]

What test was done and what were actual results and reference ranges?  Symptoms?  

[Cathyhvt]

Haven't picked up the paperwork and didn't hear the numbers. Was in shock after having NO thyroid for 19 years and NO meds for 6, to have "normal" levels.

[gimel]

Just because thyroid related tests are in the so-called "normal" range does not mean they are optimal for you.  

In trying to assess a hypothyroid patient's status, the most important consideration is symptoms, followed by tests for the biologically active thyroid hormones, Free T4a nd Free T3.  Since hypo patients are so frequently deficient in Vitamin D, B12 and ferritin, those should also be tested.  

So please tell us about any symptoms you have.  Also, what is your thyroid med and daily dosage.  Also, please post your thyroid related tests and reference ranges show on the lab report.

No meds for 6 years. First blood test in 7. Was on Synthroid until 6 years ago.
