Both high potassium (hyperkalemia) and sodium (hypernatremia) can indicate kidney function issues in IgAN. High potassium is particularly concerning and requires quick attention. Talk to your doctor about:
1. Reducing high-potassium foods
2. Reviewing your medications
3. Following a kidney-friendly diet
4. Getting regular blood tests

Always work with your healthcare team to monitor and manage these levels, as they can affect heart function. Your doctor may need to adjust your treatment plan.
