Sevelamer is a medication commonly prescribed to patients with chronic kidney disease, particularly those undergoing dialysis. Its primary function is to act as a phosphate binder, which means it helps reduce phosphate absorption from the intestines into the bloodstream. Elevated phosphate levels are a significant concern for these patients because poor kidney function leads to an inability to excrete excess phosphorus, which can result in a variety of complications, including cardiovascular issues and bone disease.

Given this mechanism of action, the correct dietary restriction for a patient taking sevelamer is foods high in phosphorus. By limiting phosphorus intake, patients can better manage their serum phosphate levels, thereby reducing the risk of associated health problems. Sevelamer aids in this dietary management by binding phosphorus in the intestine so that it is not absorbed, but dietary restriction remains an essential complementary measure.

Other dietary restrictions may be relevant for different medical conditions or medications, but the focus with sevelamer specifically revolves around phosphorus control. This understanding is crucial for patients and caregivers as part of a comprehensive approach to managing chronic kidney disease and ensuring optimal health outcomes.
