My question is whether or not a suppressed TSH should be of any concern, if indeed it is suppressed at 0.05 mU/L .
I have read around and am struggling to see whether this is of any matter at all if I feel largely better and my FT4 is still good.
I was diagnsed Atrophic Thyroiditis back in May 2017 when my TSH was 146. Severe/profound hypothyroidism and no palpable thyroid. A lot of water has flowed under the bridge since then! My endocrinologist recommended my GP get my TSH to around 1mU/L .
A brief history.
Month --------------------TSH-mU/L--------------------FT4-pmol/L--------- Levothyroxine
Mar - 17 154.00 negligible
May -17 146.00 0.14 50mcg up to 75
Jul -17 26.57 10.30 up to 125
Aug -17 0.09 16.50 remain at 125
Oct - 17 0.03 16.50 remain at 125
Nov -17 down to 117.9
Jan-18 0.05 15.70 up to 119.0??
I have a constant weight of 80-82kg (down from 95kg in May 2017).
In October 2017 my GP suggested I was over-medicated. At first I did not agree, but soon had to admit I was. Symptoms: tremor, too hot, blood pumping strongly, jumpy, startled, irritable, aggressive, darting attention, hunger pangs, bursting energy, thirsty, loose stool.
Mid Nov 2017, I reduced my dosage from 125mcg Levothyroxine to 100mcg for two days in every 7 days = 117.9mcg per day. After 2 to 3 weeks I changed dramatically. Calmer. By Christmas I believe I was experiencing some hypo symptoms - aches in leg/hip/back, drier skin/hair, fatigue, breathlessness, voice change, constipation. Less so now. Otherwise, my ongoing challenges are slightly improving. Brain fog, the same memory loss and the very strange and difficult realisation of the path of my mental health over the last 5 years or so.
I agreed this week with the GP to adjust slightly up by skipping 25mcg every 4th day =119mcg. However, my TSH is still low and I don't know whether this should be of any real concern. All Liver, Kidney and other blood results are ok. I think I feel slightly under still, but quite okay.
