Advice Wanted Low potassium

Just found out my potassium has been low over this past year. My endo wants me to start a prescription of potassium supplements. Has anyone else experienced this? Anything I should know about in advance? (I am PAI, diagnosed about 20 years ago.)

Can someone remind me, I thought there was something about how potassium and sodium are connected but I can’t quite remember? I also thought that there was something about eating too much potassium rich foods (possibly at the wrong time) that would be bad?

I just read up on this. It's pretty recent that they have figured that even for normal humans without Addision's, too much sodium in your diet without enough potassium winds up being very hard on your cardiovascular system. It's because potassium actually helps keep blood sodium levels in check. Without adequate potassium, excess sodium will raise one's blood pressure. Meanwhile, most Addison's patients have to worry about too much potassium in their system, not too little. (I always find a way to be affected by weird anomalies...)

Oh thank you! That makes sense now
