Dietary Fiber and Hyperkalemia in Dialysis Patients

The Role of Dietary Fiber on Hyperkalemia in Hemodialysis Patients

To analyze the dietary nutrition and dietary fiber (DF) intake of maintenance hemodialysis (MHD) patients, and explore the effect of dietary nutrition and DF intake balance on the nutritional status and pre-dialysis hyperkalemia of MHD patients.

A total of 100 MHD patients were retrospectively enrolled, including 67 males and 33 females. The daily diet was recorded by 3-day dietary recording method. The daily average dietary nutritional intake and DF intake of MHD patients were calculated by professional software. Dietary guidance and analysis were conducted according to the Expert Consensus on Nutrition in Chronic Kidney Disease (2005) and the Dietary Guidelines for Chinese Residents (2016). Of the 100 patients, 37 had hyperkalemia (serum potassium > 5.5 mmol/L) before dialysis.
