Thyroid Results

[nickybeans]

Can someone tell me if my thyroid results are normal? I just went for bloodwork and I too suffer from heart palpitations, cold hands and feet, weight gain, fatigue but it would appear that they rae normal. Any feedback would be appreciated. My TSH is 0.97 ..the normal range is 0.30-4.00mlU/L , my free T4 is 18 , the normal range is 9-23 pmol/L and my free T3 is 5.3 , the normal range being 3.5-6.5pmol/L . This is all from my labs results yesterday. Help?

Hypothyroidism is associated with higher triglycerides and higher glucose in addition to higher cholesterol levels.  All of these can be risk factors for heart disease.  Proper treatment with thyroid med(s) can bring these levels (closer) to normal.

Heart palps can be related to a number of things, including hypothyroidism.    Since you have other symptoms that are frequently related to hypothyroidism, I think I would want to get those tests done, especially Vitamin D, ferritin and  the saliva cortisol tests.  Then you should be able to identify symptoms are  related to deficiencies in those areas, or if you need to raise your Free T3 level a bit with some T3 med.    

B12 should be in the very upper end of its range.  High cholesterol can be a symptom of hypothyroidism also.  Also there are some things that can be done to increase HDL.  So what was your cholesterol level and reference range?

I would not worry about that glucose result.   Were you fasting for the test?

Thank you for all your info. I failed to mention that I had half of my thyroid removed ten years ago(  begnin nodule on it)   and have not been feeling well for at least 5 years. I am on 0.075 Synthroid. My heart palpiations can last up to 46 min. I did go to emerge for the first time last week..had an ultrasound to check on blockages in legs , stomach , lungs,  had an angio, Everything came in ok. So that is why I am thinking thyroid? My vit B12 came in within range magnesium great too..the only thing that came in is the Cholesterol/ HDL ratio is 3.5 and it looks as though it should be below 2 or equal to two? Don't know if you know anything about cholesterol possibly affecting the heart ? the glucose testing came in at 5.4 and normal range should be 3.5-6.0..Is that high? Thanks again if you have any other info...much appreciated!!!!!

You do have symptoms that are frequently related to being hypothyroid.  Your thyroid test results would not ring any alarm bells with most doctors.  Your Free T4 is at 65% of the range, and our usual recommendation is mid-range at minimum.  Your Free T3 is at 60 % of its range, which is a bit low for some people, but not a strong indicator.  

Since serum thyroid levels are not the only possible cause for hypothyroidism, I suggest that you should investigate others first.  I would test for Vitamin D, B12, ferritin, and a full saliva cortisol panel (4 tests taken at different times of the day).  Doctors are reluctant to do the saliva cortisol tests, preferring instead a single morning serum cortisol test; however, that is not nearly as predictive as the saliva tests.  Deficiencies in any of these  can cause symptoms, plus cortisol is an antagonist of thyroid hormone, so it can be important to know about that.

If you can get those done, and post results here, along with ranges, we will be happy to help interpret and advise further.
