What's Potassium and Why It Matters
It's a mineral that helps with nerve signals and muscle contractions. When kidneys fail to excrete it, it builds up—possibly causing heart arrhythmias.
Potassium Risk by Stage
- Stage 1–2: Usually no restriction
- Stage 3–4: Monitor & moderate
- Stage 5 / Dialysis: Strict control, often low-potassium diet
