Well done for losing weight, that should help reduce your AF.
The dose of 2.5mg Bisoprolol is very low, so no need to worry about that. I'm a lot lighter than you, but at times have been on a lot higher dose. Do you have a monitor to check what your heart rate and BP is?
Probably not, a low dose. That said, if you're getting side effects from it, ask your doctor for a short trial off of it to see if it's making any difference in your afib frequency and duration. The good news is that it appears your weight loss has lowered your afib burden which is backed by study data. Congratulations on a job well done!
Just read a book by Jay Clarke called How I cured my afib. He mentions lots of things we can do to ease the afib burden but the single biggest thing one can do according to all studies done, is lose weight. So a massive well done ! 2.5 mg is low but you can go down to 1.25 which I believe is the lowest, you could give it a trial run to see if you can cope ok and if not just go back to 2.5.
I don't think it does work like that. Most people get none or few side effects, and I can't say that I notice any, taking half your dosage, except that any side effects get mixed up, for me, with heart troubles as I get AF irregularly but palpitations daily. Mostly, the effect is to lower my heart rate, but I can't say I notice that unless I measure it.
2.5mg of bisoprolol is a fairly standard maintenance dose, from what I can tell, with 5mg given often to stop an episode. Some people are given double that. I try to take the lowest I can as my heart rate is already low.
Well done on the weight loss 😊I don’t think weight affects Bisoprolol either. I’m 1.74 ( 5 ft 8) and 10 st 4 and my HR is the same on 1.25 mg (which I’ve been on for about a year) as it was, when I was on 2.5mg, strangely, no difference whatsoever.
Like others have said though, you could ask your Dr about going down to 1.25 ( if you do, reduce VERY slowly). I did feel a bit tireder on 2.5 than I do now, but that’s about it.
My first thought was yes or even your dose is too high for your current weight seems low for your height but guess depends on your bone build (healthifyme.com/blog/height... My second question is did you mean to lose weight? I was on low dose of 1.25mg Bisoprosolol and 1/4 Flecainide and dropped a stone in a few months. My muscles shrivelled to nothing. As a woman I was sent to a dietician after the EP said “uncommon” to lose weight despite it being listed as a risk factor! After my ablation and I went off all meds, and with dietary intervention, it’s taken nine months to regain the weight I lost! I’ve hit my weight goal of 55kg (nearly 9 stone). I’m 5ft5 and tiny build!
I asked as I wasn’t trying and blame the beta blockers. Probably best to check dose to weight ratio with your cardiologist / GP but my experience was unless you protest (complain of symptoms) about dose they won’t change it
I lost 2 stones when I was having a lot of AF and found it was very helpful, but as someone has mentioned you might talk to your cardiologist about it. Good for you on your weight loss!
Excellent re the weight loss 👍 - when I was on high doses of Bisoprolol (15mg) it made me so tired and the AF was constant I couldn’t do much activity. Following ablation last year it took 4months to get NSR. The weight loss & to now be in NSR I’m only on 2.5mg Bisop, have more energy and can do more so the weight staying off is all I have to offer but hope you continue your progress.
