What dietary change would be necessary for a patient with kidney disease?

For a patient with kidney disease, a reduction in sodium intake is crucial primarily due to the kidneys' compromised ability to excrete sodium effectively. When sodium intake is high, it can lead to fluid retention, hypertension, and further stress on the already impaired kidneys. Managing sodium levels helps to control blood pressure and minimize fluid overload, which is particularly important in the context of kidney function.

Patients with kidney disease often experience changes in fluid and electrolyte balance, making it essential to monitor and adjust sodium intake as part of their dietary management. A lower sodium diet can also help reduce the risk of complications associated with kidney disease, such as cardiovascular issues.

In contrast, increasing fluid intake might lead to added stress on the kidneys, while increased fiber intake, although generally beneficial, does not specifically address the essential dietary modifications required for managing kidney disease. An increase in protein intake is typically not recommended unless the patient is on dialysis, as a high-protein diet can further place a strain on kidney function.
