help with results


I have been hypothyroid for 20 years and diagnosed with hashi many years ago. Usually I am fairy stable on a dose of 125mg. I have had a semi thyroidectomy and there was a spell after that when I needed 150mg and it took a while to stabilise.

Over the last 6 months I have had spells of feeling really unwell, dizzy, sick, v tired and unable to sleep. My doctor said my blood tests indicate I was over medicated and need to lower my dose but to repeat blood test 3 weeks later. The second blood test showed i was undermedicated to the dose was raised.

I have now had another blood test and once again I am over medicated.

Is it common for hashimotos to give these erratic symptoms one day fine the next day feeling terrible? I am also coming up to 50 so maybe menopausal.

I have finally got my results from the Dr and would appreciate any comments on them as I want to be prepared when I make a face to face appointment

I am still unsure s to why my levels change so much and is there anything that can be done to stabilise them.

The ranges are T4 11-22 TSH 0.27 - 4.2

Hi The thyroid often gets worse with age. You also need a Fee T3 test, as quite common to suddenly need T3 with the levo( T4), Only the tests show this. Most people find T4 at a third of the top of range and Free T3 near the top, is best for them.

I am struggling to sort out your results, but that should cover it.There is a test for post menopausal levels, if you feel that might help.

Best wishes,

Many thanks Jackie. I am going to the Dr this afternoon so I will ask if I can have all the tests you suggest.
