@kidneysolution2: “Watch your potassium.” Most kidney patients hear this at every appointment. Almost none are told what happens when it gets too high, what happens when it gets too low, or exactly how to keep it in the range that protects their heart and their kidneys. Too high - irregular heartbeat, muscle weakness, and in severe cases, cardiac arrest. Too low - cramps, fatigue, dangerous heart rhythm, and muscle paralysis. Both are real. Both are preventable with the right information. Join our 30-Day Kidney Fix Challenge… Save this. Share it with every kidney patient who has been told to “watch potassium” but never told what that actually means.
