Vigdis - too much FT3 - if a doctor has a firm view of this then they can be dogmatic. It may be hard to change their minds. Some people have bought my book and highlighted the areas that discuss this. Others have taken some copies of my blogs in.

It may be easier to get the doctor to examine the person, listen to their heart, take their blood pressure and have the discussion about what exactly is the 'hyper' symptom that the doctor can see - there will not be one usually. Also the FT3 is a blood level hormone. Trying to make the point that this is not necessarily what is active in the cells is an important point.

Some people have given or loaned their doctor my book.

Sometimes if a doctor is stupid or rigid then you have to change doctor.

The other approach (which is more sneaky) is to fiddle the blood test by taking less thyroid hormone for 24-36 hours before the test to lower FT3 and raise TSH. For someone taking NDT or T3 this is easy to do. If it is hard to find a new doctor and you don't want the argument with someone who is stupid then doing this can be the only easy way to avoid the argument.

Blood tests can be useful for diagnostic purposes but for fine tuning of thyroid hormones invariably they are just a way of keeping doctors happy, because doctors are not using the most important data - symptoms and signs.
