Monitoring fluid intake and weight gain after hemodialysis
Fluid Intake After Hemodialysis: Investigating the Relationship Between Time and Weight Gain During the Interdialytic Interval
This study looks at how drinking fluids and gaining weight between dialysis sessions affects people who are on chronic hemodialysis.

What this trial studies
This observational study aims to investigate the relationship between fluid intake and interdialytic weight gain in patients undergoing chronic hemodialysis. Approximately 20 participants will self-monitor their weight and blood pressure during the week between dialysis sessions. They will complete questionnaires and use medical-grade scales and blood pressure monitors to log their measurements four times daily. The study seeks to understand how fluid loss during hemodialysis affects thirst and subsequent fluid intake.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older who are on thrice weekly maintenance hemodialysis.
Not a fit: Patients with diabetes mellitus or significant residual urinary volume will not benefit from this study due to potential biases in thirst assessment.
Why it matters
Potential benefit: If successful, this study could help optimize fluid management in hemodialysis patients, potentially reducing health risks associated with excessive weight gain.
How similar studies have performed: While the approach of monitoring fluid intake and weight gain is not widely tested, it builds on existing knowledge of fluid management in dialysis patients.
