My husband has had varying results over the last couple of years but is not on any medication and has no symptoms. The last 2 lots of results are as follows:
Free T4:. 14.5 (range 10 - 18) and TSH: 9.32 ( range 0.30 - 5.00)
2 months later
Free T4: 9.3 and TSH 6.23 - same range as above.
He has lost quite a lot of weight over the last year because he has been on a very healthy diet with no sugar and no dairy and drinking smoothies each day. I was concerned about the goitrogenic greens in the smoothies and added dried seaweed and a kelp tablet daily to his diet. The doctor said to come off the kelp and the second result is what happened with no kelp. Can anyone explain what is happening? He does not want to take medication.
