What impact does chronic kidney disease have on electrolyte balance?

Chronic kidney disease (CKD) significantly affects electrolyte balance in the body, primarily leading to imbalances such as hyperkalemia, which is an elevated level of potassium in the blood. As kidney function declines, the kidneys become less efficient at filtering and excreting potassium. Since potassium is essential for normal cell function, muscle contraction, and cardiac function, an accumulation can lead to serious health complications, including arrhythmias and muscle weakness.

In patients with CKD, the impaired ability to regulate potassium is a critical concern, necessitating careful monitoring and management of dietary potassium intake and potentially the use of medications that help manage potassium levels. This imbalance is a direct result of the kidneys' inability to perform their filtering role effectively as the disease progresses.

Other options do not accurately reflect the impact of CKD on electrolyte balance. For instance, while it is true that CKD can lead to calcium imbalances, it does not always result in hypocalcemia—this condition can vary depending on several factors, including dietary intake and the stage of the disease. The suggestion that CKD improves the body's ability to excrete waste products is incorrect, as the disease leads to a decline in this critical kidney function. Finally, asserting that CKD has no significant
