Three things to know
- The number, symptoms and speed of change all matter.
- Diet is only one possible contributor.
- Do not try to correct a serious result with home remedies.
High potassium explained
Potassium helps muscles and the heart work normally. Kidney disease and some medicines can raise potassium; sample problems can occasionally produce a falsely high result. Your clinician decides whether a repeat sample, ECG or urgent treatment is needed. A possible sample error is not a reason to ignore instructions.
Low sodium explained
Sodium concentration reflects the balance of sodium and water in the blood. Low sodium can occur with medicines, illness and problems affecting water handling. It does not always mean you need more dietary salt. Severe or rapidly changing levels can affect the brain.
Read an electrolyte result in context
How evaluation works
Your care team may review kidney function, glucose, medicines, supplements and fluid intake, sometimes with blood and urine tests. Ask about potassium-containing salt substitutes and over-the-counter products. Do not stop prescribed treatment unless your treating team advises it.
Why treatment is individualized
Correcting an electrolyte disorder too quickly or in the wrong way can cause harm. Treatment may involve medication changes, monitoring or hospital care. A long-term eating or fluid plan should be based on confirmed results and the underlying cause, not a generic restriction list.
Questions to bring to your visit
- How urgently should this be rechecked?
- Could a medicine contribute?
- Do I need a specific diet or fluid plan?
Common questions
Can high potassium be symptom-free?
Yes. Follow the instructions given with an abnormal result even if you feel well.
Should I increase salt for low sodium?
Not without medical advice. The cause and water balance determine the treatment.
