I am trying to track down why my BP and temp has dropped so much suddenly. Maybe I should be in the hormones section as it's possible it's down to that but I will post here and see what people think. I am keeping quite close track of my BP/HR and temp as I am on T3/liothyronine only since Feb, and at one point was also doing Paul Robinson's circadian rhythm trial for the adrenals. However I had a saliva test back in July with a high first of the day result and therefore this was contraindicated. Since then during October I had a lot of stress with toothache, needing antibiotics (first in 25 yrs), and then an extraction (24th) which didn't go well and needed 3 lots of anaesthetic (local). I have felt pretty bad since, first with a week's flare of an autoimmune skin condition (now calmed down). However, during this time my BP and temp was not too bad, and I carried on with the same dose of thyroid meds. In the last few weeks however I have eased up slowly one of my doses but only by 5mcg. Since about a week ago my BP and Temp have been falling. I did have a very bad patch of fatigue and brain fog last week but that is now improved, just the BP and temp still low. For example, one evening this week I took my BP and it was 94/49 which I think is the lowest diastolic I have ever recorded. I was a bit dizzy a week ago, but now I am not, and today I went out, and was doing quite a bit of activity for a couple of hours. I took it when I got in and it was only 88/51 with a temp of 36.2, and pulse was actually quite low for me after all that movement at 74. I am 61, and have had low BP as long as I can remember, but it's gone down by about 10 points at the moment. I am also having a lot more muscle pain especially as I wake. Is this likely to be all down to the adrenals? I am back on CT3M to see if I can help that with this approach, but other than that wondered if it could be anything else. I have started 2 new supplements in the last month, but seems unlikely to be related......Chlorella, and NAC Detox Regulators (Selenium, Molybdenum and NAC) - just one a day of the latter.
