Hi All, wondered if anyone can advise please? I was diagnosed underactive thyroid must be over 5 years ago now. Built up to 100mg levothyroxine to get within range. Having annual blood tests and all ok.
My TSH levels have increased gradually on annual monitoring but still within range just about (Jan 17 was 5.07 but no change in medication prescribed).
I had a pre assessment at the hospital in Feb 18 due to needing operation/s. TSH came back as 5.8 and T4 15. The Dr at the hospital advised me to get it checked with GP as I was outside of range.
I've now had the ops and have been physically inactive for about 2 months. I just had another blood test via the GP which has come back as TSH 1.69, T4 14. I was quite surprised TSH had reduced so much, especially due to current tiredness, and wasn't sure if I needed to make an appt to discuss with the GP.
Will have surgery/being inactive distort the results?
Any advice gratefully received, thanks.
