What should individuals with chronic kidney disease monitor closely due to its impact on kidney function?

Individuals with chronic kidney disease need to monitor serum potassium levels closely because the kidneys play a critical role in regulating potassium balance in the body. When the kidneys are not functioning optimally, they may struggle to excrete potassium effectively. Elevated potassium levels, known as hyperkalemia, can lead to severe complications, including cardiac arrhythmias and potential heart failure.

Monitoring potassium levels allows for timely interventions, such as dietary adjustments or medications, to help prevent complications associated with high potassium levels. This makes it essential for individuals with chronic kidney disease to pay careful attention to their serum potassium, as managing this electrolyte is crucial for maintaining their overall health and kidney function.
