Potassium helps muscles and the heart work properly. When the kidneys are not filtering well, potassium can build up and become dangerous.
Healthy kidneys help keep potassium in a safe range. In CKD, that balance can get harder to maintain, especially with certain medications or advanced kidney dysfunction.
High potassium can be serious because it can affect the electrical rhythm of the heart.

Not every kidney patient needs a low-potassium diet. The right advice depends on your labs and medications.
Food changes, medication review, and repeat lab testing usually work best when they are tied to your actual potassium trend.
