What is the possible risk associated with high potassium levels in patients undergoing dialysis?

High potassium levels, known as hyperkalemia, present a significant risk, particularly for patients undergoing dialysis. Elevated potassium can lead to serious heart issues such as arrhythmias or even cardiac arrest. This is because potassium plays a crucial role in maintaining the electrical impulses that regulate heartbeats. When potassium levels are too high, it can disrupt these impulses, potentially leading to severe complications.

In dialysis patients, the kidneys are unable to effectively filter out excess potassium from the blood. Therefore, managing potassium intake and ensuring effective dialysis is essential to prevent hyperkalemia. While other conditions like bone fractures, vision problems, and neurological disorders may have various contributing factors, they are not primarily associated with the acute risks posed by high potassium levels. Heart issues are the most immediate and dangerous consequence, highlighting the critical importance of monitoring potassium in patients receiving dialysis.
