Great question — and an important one with CKD! Normal blood potassium levels are generally between 3.5 and 5 millimoles per liter (mmol/L). Potassium is considered high when it goes over 5 mmol/L, and most symptoms tend to appear when it reaches above 6 mmol/L. That said, with CKD you don't need to wait until levels are dangerously high to reach out to your doctor. It's worth contacting them if:

- Your levels come back above 5 mmol/L, even without symptoms
- You notice symptoms like nausea, muscle weakness, tingling, or belly pain
- You experience heart palpitations, chest pain, or shortness of breath — these need immediate medical attention (call 911)

Since high potassium can sometimes have no symptoms at all, regular blood tests are really important for staying on top of things. Your doctor can also help you understand your personal risk and put a monitoring plan in place.
