Hi Oxman, I've had crohns for 17 yrs, since I was 18. Have had surgery, been on all the meds. (You know how it goes) I found out the hard way about a year ago exactly what low potassium can do to a body. One of the symptoms is a irregular heartbeat. Low potassium can be caused by diarrhea or chronic loose stools. I ve had my potassium drop on me 4-5 times now in the last year, it seems like once it happens it will happen again & again, quicker & easier each time. I'm actually on a potassium drink 4 times a day now because it dropped last week and I didnt have a change in my bathroom routine but I do have loose BM's as I've had surgery & have what they call short bowel syndrome on top of my crohns. Just means I don't digest certain things as well cuz I don't have enough intestine to get the job done. (the fun never stops?) There are a lot of symptoms for low potassium, you can do your own research if your interested. But I wouldn't just accept skipped heartbeats or in my case it feels like a flutter in my chest, just because we CAN be low in certain vitamins & nutrients doesn't mean HAVE stay that way. Take care
I was diagnosed with PVC's around the same time I found out I had Crohns (3 1/2 years ago). I too believe there's a link between digestive diseases and PVC's.
Overall, I've done pretty well and haven't had as bad of symptoms as some and I'm thankful for that.
