Hello! I have been prescribed 25mcg levothyroxine after blood results showed elevated TSH around the 4.6/4.9 range over the last few months. The most recent results were:
Reference range 0.30-6.00
Free T4 14.2
Reference range 10.0-22.0
My GP told me when i was tested 10 years ago, my TSH level was 6.4 back then! (I was at university at this time and living quite unhealhily). This indicates a reduction in TSH level without medication over a decade. I thought the thyroid would gradually get worse over the years without treatment.
This leads me to question whether there could be another cause for my subclinical hypothyrodism? Perhaps a nutrient deficiency or adrenal problem?
In terms of symptoms am not overweight but am cold alot and have a slow heart rate - 48bpm! The doctor asked if i was a professional athlete!!!
