Purpose: The purpose of this study was to explore the experience of fluid management in hemodialysis patients by describing howthey manage fluid intake and what affects fluid management. Methods: Purposive sampling yielded 11 patients who have receivedhemodialysis for one year or longer in one general hospital. Data were collected through in-depth interviews and analysed using Giorgi’sphenomenological method. Data collection and analysis were performed concurrently. Results: The findings regarding how hemodialysispatients manage fluid intake were classified into four constituents: ‘recognizing the need for fluid control’, ‘observing the statusof fluid accumulation’, ‘controlling fluid intake and output’, ‘getting used to fluid management’. The factors that affect fluid managementof hemodialysis patients were revealed as ‘willpower’, ‘change in the mindset’, ‘support system’, and ‘emotional state’. Conclusion:The study results show that hemodialysis patients manage fluid intake through food and exercise as well as interpersonal relationships. These findings suggest that strategies in the development of nursing interventions for hemodialysis patients should be directedat assisting them in familiarization with fluid management based on an understanding of their sociocultural contexts.
