I recently went to my doctor because I was suffering from palpitations. I've had these before, a few years ago, but my heart checked out OK then. The doctor sent me for blood tests, including thyroid function. When I got the results I was told that this was 'borderline high' and I've been asked to go for a repeat test in three months.
I've put on weight in the last twelve months, having been the same weight up to now for a number of years. But otherwise I seem to have a few symptoms of hyperthyroidism, including anxiety and a general feeling of 'jitteriness' and irritability at times. I also get double vision sometimes, if only briefly, when I've been bending my head to focus on something I'm reading and then look up. (I mentioned this to a doctor about a year ago and was told it was a kind of 'postural vertigo'.) I'm sleeping less than I used to, and often wake up in the early hours and find it hard to get back to sleep. The palpitations sometimes keep me awake, or I wake up from a dream with my heart pounding.
I'm seeing the doctor again next week with a view to getting something to ease the palpitations, and will ask more questions about the blood tests. In the meantime I would be grateful for any information anyone here can offer.
