Tsh gone down

But meds haven't gone up. So I'm on 75mcg of levo have been for months and a blood tests a few months back showed it was 3.5 blood test Tuesday shows my tsh is now 2.1. Ive been swimming lots lately and have lost a small bit of weight could that be the reason? Ive been told my vitamin d is low also but receptionist refused all other numbers as not medically trained. Any ideas I was sure my my level of levo was too low an was hoping too convince doc too increase back too 100mcg but I doubt That will happen now with it going down

Nettiboo, TSH 2.1 is too high for most people on Levothyroxine who will usually feel better with TSH just under 1.0. Read Treatment Options in Email for a copy of the Pulse article if you would like to show it to your GP.

The GP receptionist doesn't need to be medically trained to read you your results. Contact the senior receptionist or practice manager and ask for a printout with ranges. If vitD is low you need to know how low in order to determine the dose you need to supplement.

No, swimming and weight loss would not make your TSH go down.

But, do you always have your blood tests at the same time? And are they always fasting tests? Do you leave 24 hours between your last dose of levo and the test? All these things could have an effect on the TSH.


Hi grey goose I'm very sorry for late reply my blood test are in the mornings mostly before nine am and fasting and last levo would be over 24 hours as I take about 11pm at night so miss night before test. This blood test was about quarter past nine department was running late. Thanks for reply
