Low resting heart rate

[tigertummy]

I know not to pay too much attention to my Fitbit but I've noticed a bit of a pattern.

Every few weeks I have a week of feeling dizzy, faint and generally foggy and odd. (It doesn't seem to tie in with my very irregular periods.) Looking at my Fitbit data it shows that during these phases my resting heart rate comes out below 60 where it's usually 65-67.

I'm speaking to the GP tomorrow but was wondering if you lovely lot had any ideas...

Hypothyroidism can cause this, at least that’s what’s causing mine!

@Ostryga I'm already on levothyroxine for hypothyroidism. I had my levels checked th week before last and they were fine. Although that was when my heart rate was normal.

How old are you? Could it be perimenopause related? Fogginess was my primary symptom although never experienced dizziness.

@illiterato mid thirties. My mum did go through menopause early so it's possible.
