Background: Hyperkalemia and Hyperphosphatemia are common among Hemodialysis (HD) patients. It is caused by the excessive ingestion of potassium and phosphate-rich foods. Dieting helps reduce this increase in blood serum also they use an oral phosphate binder medication can to help lower phosphate absorption. However, some characteristics of using phosphate binders are associated with poor adherence. Additionally, the hemodialysis patients mentioned some side effects of the medication. Monitoring nutritional parameters is an important factor for treating hemodialysis patients. Nutritional intervention by a dieticianis key when managing hyperkalemia and hypophosphatemia. The aim of this study was to evaluate the effect of the dietician educational program to control hyperkalemia, hypophosphatemia and phosphate binder among HD patients in the hemodialysis charity center (Hisham Attar Dialysis Center), Jeddah, Kingdom of Saudi Arabia. Methods: a comparison was made between HD patients before and after a nutritional educational program. A group of 190 patients was assessed using medical history, hemodialysis status, An thropometric measurements including [height, weight after a dialysis session and body mass index (BMI, kg/m2)]. Plus, biochemical measurements including (Potassium and Phosphate) levels were examined. Furthermore, groups of HD patients received teaching sessions by a dietician. An individual meeting with each one of the HD patients or with his/her family was held in a dietician clinic room. Next, data were collected before and after the nutritional educational program. Results: a significant decrease has been found in the average levels of potassium from before the program as compared to 1to 3 months following the program. The laboratory results for phosphorus levels showed a significant increase in Phosphorus after 1to 3 months from the nutritional educational program. A significant decrease of Phosphorus binder was observed after the nutritional educational programat (P ˂ 0.05). Interventions involving the nutritional educational program supported the adherence of dietary recommendations additionally, positive changes and improvements to HD patient health status were found. This study suggested that repeated, personalized nutritional educational program is an effective way to improve patient care as well as to prevent abnormal potassium and phosphate parameters and reduce the use of phosphorus binder medicine.
