Introduction: Hyperkalaemia and hyperphosphatemia are electrolyte imbalances
commonly diagnosed in chronic kidney patients, originating from both food and other
factors, with a risk of death if there is no proper control. Objective: To identify whether
food influences the hyperkalemic and hyperphosphatemic conditions of chronic renal
patients. Methodology: Qualitative, quantitative, crosssectional, prospective and
descriptive study with 65 patients from the Hemodialysis Center Monteiro Leite.
Where, data collection was carried out from a questionnaire on epidemiological,
socioeconomic, sociodemographic and biochemical issues; in addition to the analysis of
food consumption made with the application of the food frequency questionnaire and
three 24hour reminders, with the approval of the Ethics and Research Committee under
opinion Nº 2.970.945. Results: It was identified that the majority of the population
belonged to the male gender and adulthood, with major diagnoses of hypertensive
nephrosclerosis and diabetic nephropathy, with prevalence for treatment of 15 years
and individual and family income of 12 minimum wages, significant percentage for
incomplete elementary education, naturalness with percentages close to capital and
interior and high provenance for capital. In the intake of potassium the majority is
below and of phosphorus a relevant amount above the recommended. Still, there was a
predominance of normocalemia and hyperphosphatemia, with correlations with
ingestions: nonsignificant weak and significant weak, respectively. Conclusion: In this
way, it is concluded that food intake can influence the potassium and phosphorus
elevation conditions, however it is not the only nor the main cause of the studied
hydroelectrolytic changes.
