Hi! I’m new here. I have been struggling with my endo for a diagnosis. About a year ago I had many blood draws where my TSH was very low, my T4 was low and my T3 was normal. I was not medicated. My doctor did not know how to treat me, but I was very hypo symptomatic. After some time my TSH regulated but he would not test my T3/T4. He referred me to an endo and I received my results today.
TSH .99 (.35-5.0)
T3 Free 3.9 (2.6-5.7)
T4 Free 9.2 (9.0-19.0)
I’m including my insulin and c-peptide results I’m not sure they are relevant.
C-peptide 249.0pmol (298-1324)
Insulin 33.8pmol (43-194)
Thank you for the information.
Test results, are they actually normal?
Thyroid results - are these normal?
Results been told normal
I would expect a much higher TSH with your low fT4, in this case you would then be diagnosed as hypothyroid.
Strict dieting can reduce TSH and thyroid hormone levels. I know nothing about insulin but is it possible your low insulin levels are causing malnutrition? If this is the case and it could be corrected your TSH might pick up and stimulate your thyroid to produce more hormone.
It looks like your TSH is too low rather than any problem with your thyroid.
Thank you for the information. I am not currently dieting, I would say currently my diet is not as clean and strict as it typically is. I will clean up my nutrition again, I won’t diet strictly and I will see if there are any improvements to my symptoms.
Just to clarify I wondered if the low insulin was having the same effect as being on a diet - reducing your available calories. I have to little knowledge of insulin so just raising the possibility.
Ahh yes! That is a good question. I will dig deeper. It’s a good hypothesis. I don’t know much about insulin either. I had been trying to research about thyroid issues, and the insulin results popped up in one of my blood draws. My endo requested it. She’s very hard to get any diagnosis from, or any information either.
