What dietary advice is recommended to prevent hypertension in patients with chronic kidney disease (CKD)?

Limiting sodium intake and following a low-sodium diet is the recommended dietary advice for patients with chronic kidney disease (CKD) to help prevent hypertension. Sodium plays a significant role in regulating blood pressure, and excessive sodium intake can lead to fluid retention and increased blood pressure, which can exacerbate the progression of kidney disease and elevate cardiovascular risks.

In CKD patients, the kidneys are often less effective at excreting excess sodium, making it crucial to manage intake in order to control blood pressure and avoid additional strain on the kidneys. A low-sodium diet generally involves reducing sodium intake to less than 2,300 mg per day, and ideally even lower for those with more advanced stages of CKD or existing hypertension. This dietary modification helps to improve blood pressure control, reduce fluid overload, and ultimately contribute to better overall health outcomes for patients with chronic kidney disease.

The other choices, which suggest increasing sodium intake, adopting a moderate sodium intake plan, or consuming high-sodium snacks, are not aligned with established guidelines for managing hypertension and CKD and could potentially lead to worsening health issues for those affected.
