Synthroid and Exercise

[Johnny Trackmarks]

I'm on 150 MCG Synthroid a day. My thyroid is 95% degraded. My last TSH test was 8 something.

I've read excessive exercise can deplete Synthroid. Do any of you on Synthroid/Armour tweak your dosage in relation to your exercise regimen?

I've read about Galen Rupp and many runners being "diagnosed" with thyroid disorder in order to get their hands on a Synthroid RX.

Who can shed some light?

I don't tweak my dose (224mcg) based on exercise, but I have noticed that my TSH has remained elevated (5+) in the last couple of years since I've been working out 5-6 days a week.

Never thought that the TSH fluctuation could be cause by exercise. My endo knows I work out regularly and has never brought it up.
