Wow - never heard of that before. What type of surgery were you scheduled to have? Up until May of this year, my TSH had been suppressed for the past 12 yrs. I've had a couple of surgeries - one just a year ago - and no one said anything about TSH level. In fact, they didn't even ask about my thyroid levels.
What was done to bring your TSH up? I assume you're on replacement thyroid hormones... did they reduce your dosage?
idiot Dr who doesn't understand thyroid treatment.
Do you have your FT3 and FT4 results including the reference ranges? If so please post them.
You said you are on medication. can you list the medication(s) and the dosage(s) also.
I would ask the surgeon, what other indication is there that you are hyper-thyroid? Ask them if TSH is an actual thyroid hormone. If they say no, then ask them what are the two primary thyroid hormones. Then show them the results that you are (assuming you are) within the reference ranges and exhibid zero symptoms (again assuming you don't). So you would then have three indications, FT4, FT3 and symptoms and clinical evidence that you are NOT Hyper.
You may also have to get your primary doctor, or whomever your Dr is that is treating your thryoid to weigh in and contact your surgeon.
Just my thoughts on the matter.
