Bananas are not the problem! Hyperkalaemia and CKD

For Kidneys Sake

For Kidney's Sake series is brought to you by Imperial College Healthcare NHS Trust and North West London Integrated Care Board (NWL NHS)
In our first For Kidneys Sake episode, Dr Andrew Frankel and Prof Jeremy Levy, Consultant Nephrologists at Imperial College Healthcare NHS Trust, discuss hyperkalaemia (high potassium levels), particularly in patients with chronic kidney disease (CKD). They explore when clinicians should be concerned about elevated potassium levels, the causes behind hyperkalaemia, and the best approaches to managing it in primary care. The episode aims to demystify the condition, provide clarity on when action is necessary, and offer practical tips for managing hyperkalaemia without unnecessary panic.

Key points include understanding spurious hyperkalaemia in primary care, recognising when potassium levels are truly concerning, and the role of commonly prescribed medications such as ACE inhibitors and angiotensin receptor blockers. The doctors also discuss treatment options like potassium binders and diuretics, emphasising the importance of maintaining heart and kidney-protective medications where possible. The episode also touches on the role of diet in managing potassium levels, clarifying misconceptions about potassium-rich foods and their impact.

Key Takeaways:

Spurious Hyperkalaemia: Often caused by delayed blood sample processing in primary care.

When to Act: Potassium levels above 6.5 mmol/L warrant urgent action. Levels between 5.5-6.5 mmol/L require follow-up but are not emergencies.

Medications: Certain medications, especially ACE inhibitors, ARBs, and mineralocorticoid receptor antagonists, can cause high potassium but are essential for heart and kidney health. New potassium binders, such as Lokelma and Veltassa, can help manage potassium without discontinuing these vital drugs.

Dietary Considerations: Bananas are not the only source of potassium. Many fruits and vegetables contain high levels, but stopping their consumption is not advisable. A balanced approach to diet is key.

Educational Resources: Potassium education sheets are available on the North West London CKD site.

This episode is a practical guide for primary care clinicians on managing potassium levels in CKD patients and balancing treatment urgency with patient well-being.
We hope you enjoy this episode.
