What is the rationale behind reducing fluid intake for some CKD patients?

Reducing fluid intake for patients with chronic kidney disease (CKD) is primarily aimed at managing conditions such as edema and hypertension. In CKD, the kidneys are less able to excrete excess fluid, which can lead to fluid retention and subsequently cause swelling (edema) in various parts of the body. Additionally, excess fluid can contribute to elevated blood pressure, which is a common complication in CKD patients. By limiting fluid intake, healthcare providers aim to decrease the volume overload, thereby helping to maintain blood pressure within a desirable range and manage symptoms associated with fluid retention. This approach is essential in the care of CKD patients, as it can improve their overall health outcomes and comfort.
