Good evening.
I am seemingly fully replaced on a combi dose of Levo and Lio and generally feel quite well in myself, can tolerate exercise and lead a normal life.
My partner commented that I was breathing very fast at night so I have started to wear my apple watch again after a few months leaving it well alone. It turns out that my resting heart rate is back down at 48. That's where it was before I was diagnosed with hypothyroidism in 2022. Since I started the medication journey it has crept up to around 59. I just can't understand how my RHR can be so low while I am fully replaced. In fact my blood test suggests that I am over replaced on T3.
Does anyone have any thoughts on how this could be?
I will probably make an appointment with my GP but I am reluctant to go that route since I get my T3 from a functional doctor and don't want to start arguing my low TSH with hospital endos.
I am now on 125mg Levo and 35mcg Liothyronine. My February fasted results with blood taken at 7.30am, (17 hours after T3 dose and 24 hours after T4 dose) are:
T3 6.9 (3.1-6.8)
T4 20 (12-22)
TSH 0.005
many thanks for any ideas.
