Which dietary restriction is commonly advised for patients undergoing dialysis?

A low-sodium diet is commonly advised for patients undergoing dialysis because it helps manage fluid retention and blood pressure levels. Dialysis patients often experience complications related to excess fluid in the body, which can lead to swelling, increased blood pressure, and difficulty breathing. Sodium causes the body to retain water, so reducing sodium intake can help keep fluid levels in check and prevent these complications.

In addition, excessive sodium intake can result in higher blood pressure, which poses further risks to patients already experiencing kidney issues. Therefore, monitoring and restricting sodium intake is a critical part of dietary management for these individuals, contributing to their overall health and treatment outcomes.
