Better fitness but more drastic variations in HR and no change in symptoms?
I've been working at an Amazon Sort Center for going on 7 months now (been in warehousing 6 years) and have noticed a drastic inprovement in my overall HR and fitness, which is good. Only mild improvements in fatigue most days, though. I've also lost 20lbs, which is also good since I need to lose 80 more.
My sitting HR has improved and more often sits in the 60s range most of the time now which is awesome because before it required meds to get there. The problem is I noticed in the last couple months that my HR gets down as low as high 30's some nights when I sleep. When this happens I feel so relaxed and good but getting up makes me feel like my lungs lack oxygen for the first half hour to hour and that relaxed feeling carries on in an uncomfortable way. My galaxy watch is set to send out alerts when under 45 for prolonged periods. Sometimes I wake up and see I slept like that for hours and I can absolutely feel it. My now laying HR is usually in the 50s. At first I loved this feeling of lower HR overall when at rest thinking it was good but now I'm second guessing it. No matter what postion I'm in I often get random increase of up to 30bpm so it fluxuates so much. In a none working, sat at home all day kind of day the range is easily 40's-110's now. Used to never go below 60's.
That said, the exercise and weight loss hasn't fixed any actual symptoms that comes with these fluxuations but instead seems to have made the ranges even greater. I also go hypertensive a lot when standing (and randomly when sitting) and often get migraines from exercise, so that hasn't changed any.
I had also read a while back that there's a real potential for more syncope issues if I lose weight due to lower blood volume, which was a greater issue for me when I was at a healthier weight, so returning to that life has me a little concerned as well. Syncope during exercise and other things happened a few times before I became aversive to it and learned the early warning signs.
Has anyone here lost weight with these strange conditions? What was it like for you?
Also to note at the end of last year I had an at home sleep test which yielded unconcerning results, a normal echo of my heart, a TTT that was "not POTS" and my EKGs were all fine over the years. So on diagnostic paper I'm "normal" but Drs are baffled. Plan to get in with a new neuro when I have insurance again.
