Hi! I just had blood work done at my oncologist office ( I'm 3 1/2 yrs out from breast cancer) and they called me and told me I had low potassium. The doctor put me on 3 potassium pills a day. I've never had this before and I'm 82. I'm sure some of my problems are do to age. Recently I had a colonostopy because of bowel problems. That turned out ok, but the stool softeners and such had cause me some diarreha and I believe this may be the problem. Some of my symptions were heart palpitations and a little shakey. Hope the pills work as I now know you can get into alot of trouble with low potassium. Best of luck finding out your cause.
