I have Hashimoto's, currently taking 50mcg Levo per day.
My resting heart rate seems to fluctuate quite regularly, I only know this because I wear a Fitbit tracker - so I notice that my resting heart rate goes from around 52bpm - 60bmp. What happens is it might be nearer the 60 mark for many days then gradually over a few days it keeps dropping till it's around 52. It will stay here then start to climb towards 60 again. This has been an ongoing pattern for many months. I also notice when it's lower I don't feel so well but when it's higher I am feeling decidedly better. Just wondered if anyone else had noticed this?
