in Health and Weight Loss
I’m 42, male and have lost about half my body weight. I’ve been very overweight and sedentary my whole life until now. I started losing weight successfully in 2015. I weigh and log everything because it works. I exercise because I can and it feels good. I walk and hike a lot but also use the elliptical and swim laps. My resting heart rate was in the 100’s in 2015 but has come down to 50’s to 60’s. I wear an Apple Watch. The past couple weeks I’ve gotten alerts for heart rates in the high 40’s. I don’t feel any distress. Anyone have any thoughts?

    My RHR is about 48 - it came down steadily as I got fitter in my 50's.
    I have no worrying symptoms so I don't worry about it. :)

    It's lower than the general population but I'm also far fitter than the then the general population too. Not that unusual let alone exceptional amongst people who do a lot of cardio.


    Advice from the NHS website...
    Most adults have a resting heart rate between 60 and 100bpm.

    The fitter you are, the lower your resting heart rate is likely to be. For example, athletes may have a resting heart rate of 40 to 60bpm, or lower.

    See a GP to get checked if you think your heart rate is continuously above 120bpm or below 40bpm, although it may simply be that this is normal for you.

    Sounds normal provided you're fit. Your heart is a muscle too and can be trained. if it beats more efficiently then it doesn't need to beat so often.

    my resting HR is 48 and been that way for couple years. I don't have any health issues. Doctor says HR is fine. During last 8 years I ran marathons and now triathlons so that is lot of cardio. I wear a Garmin HR monitor while training.
    Never had it give alert for low HR.
    congrats for keeping up with losing weight and getting fit.

    My resting heart rate at the doctor was 32 bpm, which freaked him out and he sent me to get an EKG. Turns out I just have bradycardia. Nothing to be concerned about my doctor said, usually fit athletes have lower heart rates. Think that and I have hypothyroidism causes it to be so low. Can’t hurt to get it checked out anyways if you’re concerned.

    My RHR is in the mid-40s. If you are very active and fit, and you don’t have other medical concerns, then it’s probably okay but worth mentioning with your doctor to be sure.

    Mine sits in the mid 40s as well. Low thyroid function, lots of workouts. I would not call myself an athlete even though I hike a lot and run a lot and lift a lot. But I guess it all adds up. Get it checked if it concerns you.

    Are you saying your HR goes down into the 40s during the day? Occasionally my Garmin will lose its marbles for a bit and think my HR is in the 40s or 50s during the day but it's always a measuring error. Wrist sensors aren't perfect.

    I'm 41 and my resting rate is 45-49 according to a couple years of Health data wearing Apple Watch. My blood pressure is also on the low side but always has been.

    Check with your doctor. If you feel fine and have no other symptoms at any time, the question can probably wait until your next regular physical IMO, but I'm not a medical professional, and this is a medical professional question for sure.

    There are health conditions for which bradycardia (low heart rate) is a sign. However, as others have said, it also happens as a result of fitness. There seems to be popular mythology that only elite athletes are going to have lowered heart rates from activity, but that's not true.

    I'm 63, recreationally but routinely athletic, and my RHR wanders from the mid/high 40s to the low 50s. I repeatedly set off the bradycardia alarm at an outpatient surgical center (before any drugs were administered) when it was set to alarm at 50, before my cataract surgery. I had to wave my legs in the air occasionally to prevent it continuing to alarm. My surgeon said "fitness-induced bradycardia". :)

    Completely subjectively, it seemed like my RHR trended toward my low side for quite a while right after weight loss (I'd been very active for 10+ years while obese, so my CV fitness was good, and perhaps because the blood didn't have to be pumped as far . . . ? Dunno.).

    Be attentive for any sense of shortness of breath (in general or at exertion levels that formerly didn't elicit it), light-headedness, fluttering feeling in your chest, or anything of that sort, and accelerate the doctor consult if you notice anything. Likewise if you're taking any drugs that could affect heart rate, and for which the dosage hasn't been reconsidered since weight loss. Be safe!

    56 y/o recreational athlete (running, lifting, swimming, cycling, etc.), my average RHR is 49. An RHR in the 50s-60s doesn't sound like anything unusual for a reasonably active person - but if you have any doubts, check with your doc.

    My RHR is in the 40s and often below that if I am sitting & reading. I pointed it out to my dr who did an EKG in the office and also ordered a 24-hour holder monitor & thyroid lab. Result = I have a low heart rate which apparently is just how I am wired, and causes no discernible problems. As folks have suggested, bring it up to your primary care physician and go from there.

    If you have no other symptoms then in most cases it is fine.

    I run a pretty consistent 42 bpm resting heart rate. Nothing to worry about! You could always get an ecg/ ekg for the sake of just checking in on the ticker lol

    Check your doc, but i lost a lot of weight too and have the same phenomenon. My resting HR is in 40s and the lowest min-rate went down to 28 for some mins.
    I got my heart checked but turned out it's just perfectly fit. But i have to mention in before every surgery so the anesthesist doesnt freak out xD...

    My theory is, that the heart of a former "fatguy" is trained pretty well, because it had to pump through the bigger body. Loosing weight etc. makes it easier. The heart is a muscle. In addition to that most people who lost a lot of weight are pretty fit because they do more sport than an average guy.

    If you're in a persistent deficit and exercising your heart rate does go lower. I vary almost 10 bpm (fitbit resting hr measurement which is somewhat arbitrary) between eating at a persistent deficit and eating at a slight surplus.

    I have a low heart rate but it's due to beta blockers, it makes me feel ill so I'm always at drs about it. I guess it depends the reason it is low, athletes are likely to have low heart rate, this is not the case for me. If concerned or have symptoms see your gp.

    Had a checkup today and a heart rate of 46, and that was after walking in from the parking lot and climbing 2 flights of stairs, I had to explain to the nurse that I’m a runner.

    I love the look on the nurses faces when they see it and look at me like... how are you not fainting right now? Or how are you even alive?! :D I’ll tell you what my doctor told me once when I asked him about it... he said in this case numbers alone don’t mean much, especially isolated numbers. It’s the general trend and numbers ACCOMPANIED BY SYMPTOMS that requires further investigation. Definitely mention it to your doctor and find out if there is any reason to be concerned, especially if any symptoms are affecting your quality of life. Otherwise it could just be your new normal :)

    I’m age 63 with resting HR in low 40’s. If you’re fit, you should have no concern. Do you know what your maximum HR is? When was the ladt time you worked out (cardio) and what was your average HR and peak HR for that workout?
