Dialysis and Nutrition: Optimizing Dietary Support for Patients Undergoing Blood Purification

Abstract

This study evaluated the effectiveness of individualized dietary interventions in improving the nutritional status and general health of individuals undergoing dialysis. A total of 120 patients undergoing dialysis were equally allocated to the Standard Care Group and Intervention Group. The recipients of individualized dietary counseling had their plans modified monthly in accordance with their nutritional needs, personal preferences, and clinical circumstances. Nutritional adherence, biochemical parameters, clinical outcomes, and quality of life were evaluated and compared between groups. At baseline, both groups exhibited comparable demographic characteristics. Compared to baseline values, the Intervention Group showed substantial enhancements in albumin, hemoglobin, potassium, and phosphorus levels after six months (P < 0.05). The Intervention Group had a considerably higher rate of adherence to dietary recommendations than the Standard Care Group (92% vs. 75%, P < 0.01). Nutritional intake analyses revealed a noteworthy enhancement in energy and protein consumption, while sodium, potassium, and phosphorus intake decreased (P < 0.05). The results of the quality-of-life evaluation demonstrated notable improvements in physical, emotional, social, and overall health perception scores (P < 0.05). Thus, personalized dietary interventions substantially improve the nutritional status, biochemical profile, and overall quality of life of patients undergoing dialysis.
