Hello Folks!

[sheenah]

Got to have Vascular surgery in the next few weeks. Bloods showed up that T3 and T4 were out of kilter. I don't think I have been taking enough (Thyroid - S) I have now increased the dose - Do we think that will do the job or do I need something else to boost things along?

It would help if you shared actual blood results along with their reference range.

How much Thyroid S were you taking and what have you increased to?

How did you take your blood test? Time of day and time of last dose before the test?

Recommended blood test protocol: Test at 9am (or as close as possible), fasting, last levo dose 24hrs before the blood draw, last T3 dose 8-12 hours before blood draw & no biotin containing supplements for 3-7 days (Biotin can interfere with thyroid blood results as it is used in the testing process).

Testing like this gives consistency in your results and will show stable blood levels of hormone and highest TSH which varies throughout the day. Taking Levo/T3 just prior to blood draw can show a falsely elevated result and your GP/Endo might change your dose incorrectly as a result.

For NDT testing, split dose day before test and take last portion 12hrs before the test.

just to make you aware if you are not already ~ having a supressed TSH can create issue's if having General Anaesthetic , or rather , it can cause the medics to have issues and postpone surgery .

It comes down to the opinion of the individual anaesthetist . some understand that low TSH is not a problem with general anaesthetic as long as T4/T3 levels are not too high and are comfortable to go ahead , but others don't get it and will postpone op.

so depending on what your recent TSH / fT4/ fT3 levels were, and whether you have already had pre-op bloods done or not , increasing your dose ( and lowering TSH further) could possible cause your op to be delayed while you have a repeat round of 'low TSH / lower your dose' argument with them.

some people have sorted it by simply discussing T4/T3 levels with anaethetist, but others get a brick wall.

Thanks for your responses. The nurse said that the pre-op blood TSH level was Ok but that there was a problem with T3/T 4 balance - no numbers were specified. He (the anaesthetist) also said that I needed an additional inhaler (COPD). They have put the op off for 6 weeks as I have just had a chest infection. The surgery is to remove blockages in both my groins and a couple of stents "further upstream". I have reached the point now where I can hardly walk at all - certainly not outside of my home. Such is life.

Many Thanks

NDT presents differently in blood tests to how synthetic thyroid hormones present - does the anaesthetist know you are taking Thyroid S - ?

[sheenah in reply to pennyannie]

I told the nurse so I presume he does

Did the nurse know of Thyroid S and how it presents in a blood test ?

[sheenah in reply to pennyannie]

I really don't know. He seemed to know. I shall have try and make an appointment with the GP - wish me luck - to see if I can find out more. It was all done very quickly at the hospital - I have no access to blood tests!!

GP may not have access to hospital thyroid blood results. ( different system , not neccesarily sent to GP )

I'm not sure what is the easiest way to get hold of them directly from hosp, as i've never tried , but check this out before making GP appt , other wise it may be waste of time
