Hello, for a person with kidney failure, how much fluid should he/she take per day? Also, why can't she take potassium and magnesium supplements? Thank you for your help!

Good evening,There are several factors that can influence whether or not a person with kidney failure needs to limit the amount of fluid they take: the level of failure (mild, moderate, severe), whether or not the patient is receiving dialysis treatments, and other diseases and conditions (e.g. heart failure).There is usually no fluid restriction for a person with moderate kidney failure (not on dialysis) and no heart failure

The kidney helps to keep the blood concentration of sodium, potassium and magnesium stable and in balance. In kidney failure, it is often more difficult for the kidney to eliminate excess potassium and magnesium. If this person receives too much of these elements and ends up with blood levels that are too high (the kidney being unable to maintain the balance), this can cause serious heart problems (arrhythmias)

I do not recommend fluid restriction in renal failure without dialysis.
