Elevated Potassium
What Can Cause High Potassium?
Potassium is a mineral your body needs, but too much of it can be dangerous. Here are five common reasons why potassium might be high:
- Lab Test Error (False High) Retest and notify the clinic.
Sometimes, potassium looks high on a blood test because the blood sample was handled roughly or taken incorrectly. This can cause red blood cells to break, which releases potassium and gives a false result. - Eating Too Many High-Potassium Foods – Reduce high potassium foods.
Foods like bananas, dried fruits, potatoes, spinach, and coconut water are healthy—but if you eat a lot of them, especially with kidney problems, potassium can build up in your blood. - Some Medications and Supplements – please advise you practitioner if you are taking any of the following medications.
Certain medicines can make your potassium go up, like: - Blood pressure tablets (e.g. ramipril, losartan)
- Water tablets that keep potassium in (e.g. spironolactone)
- Anti-inflammatories (e.g. ibuprofen)
- Avoid all supplements with potassium, including electrolytes, alkalising minerals and magnesium potassium powders
- Kidney Problems
Your kidneys help remove extra potassium. If they’re not working well, potassium can stay in your body and rise to unsafe levels.
