Hello everyone! I'm a 27 year old male who have been struggling with symptoms of hypothyroidism since June. However, my endo have told me that thyroid medication is not an option yet because he thinks that my current hypothyroid state is probably just a transient case of hypothyroidism.
My thyroid problem was discovered by chance in March. At that time I had some blood tests done that showed suppressed TSH, normal free T4 and elevated free T3, and I was then referred to further examination for hyperthyroidism. Since then I have had regularly blood tests done and there has been a continuous decline in free T4 and free T3, while TSH has been unchanged and thus suppressed throughout the whole period. Thus, my thyroid test results have been as follows:
End of July
* Lab normal reference ranges: (TSH: 0,3-4); (FT4:10-26); (FT3: 3,3-6,1)
* In addition, normal antibody levels detected: TPO = <28 (lab normal ref-range: <60); Thyrotropin receptor antibodies = <0,3 (lab normal ref-range: <1,2)
As shown by my last blood test, my current t4 and t3 values are too low, which currently gives me many disabling typical symptoms of hypothyroidism. However, my endo has concluded that thyroid medication is still not an option. His medical hypothesis is that I probably have had some prior inflammation in my thyroid gland which resulted in a temporary high metabolism (I never felt any hyper-related symptoms) and that my thyroid after a transitional period with hypothyroidism probably will soon stabilize again, when my TSH starts to increase, which, however it has not yet, in spite of my current low values t3 and t4. Therefore he have decided that I should wait another 3 weeks from now and then get new blood test to see if the TSH have started to increase. I'm not sure what he will suggest for further examination in case my TSH is still suppressed in 3 weeks.
Since I don't know much about all this thyroid stuff and have only been to a brief consultation with an endocrinologist, I would very much like to ask for advice and some answers to the following questions:
- How low is my current t4 and t3 values compared to typical cases of hypothyroidism?
- Is it normal for TSH to remain suppressed when t4 and t3 values are as low as they are in my case?
- And if yes, how long does it usually take before TSH starts to increase?
- Is secondary hypothyroidism with pituitary dysfunction a possible assumption in my case?
Thanks in advance for your time - and sorry if I'm not strictly following the rules of the language in which i'm writing but English isn't my native language.
