Hi,Tonia, Thanks for query, Kalium you mean potassium? If you have hyper kalamia,one should find out the cause of hyper kalamia. It is common with kidney impairment. So reduction of potassium depends upon the disease you have. If it is mild it can be reduced at home,but if it is more one should be hospitalized. Take low potassium diet, Take sodium bi carbonate to counter effect of potassium, Stop medicine causing potassium deposition. Take some diuretic. ok and bye.
