Hi I have been hypothyroid for well over 25 years. I was on 125mg per day for many years until earlier this year when a blood test revealed my TSH to be outside the lower end of range. I had been experiencing some problems with palpitations, chest pain when walking up an incline and was sent for heart scan to rule out angina, the tests came back negative. My thyroxine dose was reduced to 100mg and the symptoms went away. I moved home last year and was on 2,200 vitamin D3 for some time mainly because I have osteopenia and my level was a bit low. My new doctor after a recent dexa scan which showed much the same results as 5 years ago decided my dose of of Vit D3 was too high and prescribed 400 D3/calcium chewabe tablet. In the meantime I have had some digestive problems and investigations and I now have to take a fibre drink half an hour before breakfast. I have been taking my thyroxine and a water tablet for blood pressure just before the fibre drink as I had know you need to leave a gap before eating. It suddenly occurred to me that my thyroxine may not be being absorbed correctly because of the fibre drink. I asked my gp about taking the thyroxine at night and she said yes you can try but most patients just take it in the morning. So I have 2 questions which I wonder if anyone can help with.
1. I know there is a correlation between low VitD3 and tsh levels. My Tsh had over the years been slowly lowering so I am not sure whether I should have stayed on 125mg of thyroxine because I am taking lower Vitamin D3 or I should be on the lower dose of Thyroxine with more vitamins D3. Hope this makes sense. My gp as good as she is seems to go entirely by blood test results. They were only done in February.
2. Anyone take their thyroxine at night and can tell me what difference it has made to your health bloodtests etc. I have always had periods when I feel the cold usually at around this time of the year when the weather is so changeable. My old gp said it was just thyroid adjusting. I have been having times during the day where I feel very cold. True we have moved from the south to the north of England but even so I think it could be thryoid related. Thank you so much for reading this and if you can add anything or advice it would be appreciated.
