What is a common consequence of chronic kidney disease related to electrolytes?

Hyperkalemia is a common consequence of chronic kidney disease (CKD) due to the kidneys' decreased ability to excrete potassium. As kidney function declines, the body struggles to maintain normal potassium levels, leading to an accumulation of potassium in the bloodstream. This situation is particularly concerning because elevated potassium levels can have serious effects on heart function, potentially leading to arrhythmias and other cardiovascular issues.

In individuals with CKD, factors such as dietary potassium intake, medications, and the degree of renal impairment will further influence potassium levels, but the inherent difficulty in excretion is a primary driver of hyperkalemia in these patients. Thus, recognizing and managing elevated potassium is a critical aspect of caring for patients with chronic kidney disease.
