I'm pretty new here, but loving this forum. A few weeks ago I went to see my GP about some stomach issues. I had some blood tests done (results posted below). Initially I was found to have low iron, so I had more tests done for B12 and thyroid. It turns out I have anti-thyroid antibodies (772), and elevated TSH (5.24 - it was 4.04 when tested a year ago, but nothing was said then), which I really wasn't expecting when I returned to my GP, so it was a bit of a shock when she told me I was developing an auto-immune condition. Anyway, she seemed unsure about whether I should have treatment, she was asking me what I thought. - whether to have treatment now or wait until my TSH reaches 10. From what I have been reading, I'm tending toward taking pre-emptive action and taking Thyroxine before any worse symptoms come about. (I've also started eating brazil nuts every day for selenium!). Anyway, my doctor gave me a prescription in case I decide I want to trial the Thyroxine. I picked it up, and see that the instruction from her is to take 25 ug/day. I have read on here and other places (including the package insert of the L-thyroxine) that 50ug/day is a normal starting dose for adults. Also I read somewhere on here that if the starting dose is too low, things may become worse as the thyroid will stop/slow down producing thyroid itself, but the dosage of the exogenous/drug thyroid will be too low to compensate fully. So I guess I'm wondering if I should take 25ug as prescribed, or to go ahead and just take 50ug. She only prescribed an initial amount of 28 x 25ug tablets, so they won't last long and I'll have to go back to see her pretty soon to get more either way. I feel 25ug/day is too low, but I don't particularly want to annoy the doc and go against her instructions!
By the way, is a feeling of your heart pounding a hypothyroid symptom? I have a home blood pressure monitor which seems to indicate my BP is normal, but my heart sometimes feels like it is pounding quite hard, especially when lying in bed, although my pulse rate is not fast , being around 50bpm.
My only other symptoms are the GI issues sometimes, fatigue (but this has improved a bit since taking iron supplements), and I feel my exercise capacity has decreased (I like to distance run, but find I'm not as fast as I was, but this could just be me getting older and more unfit, and I'm using thyroid as an excuse!)
