Why is it necessary to check the weight of a dialysis patient before and after treatment?

Monitoring the weight of a dialysis patient before and after treatment is crucial for assessing fluid removal and the efficiency of the dialysis process. Weight changes during dialysis sessions primarily reflect the amount of excess fluid that has been removed. Patients with kidney failure often retain fluids, which can lead to complications such as hypertension and edema. By weighing patients before treatment, healthcare providers can establish a baseline. After treatment, the weight helps evaluate how effectively the dialysis has worked in removing excess fluid.

Weight changes directly correlate with the volume of fluid that needs to be removed during dialysis. This information is vital for clinicians, as it allows for adjustments in treatment plans and helps ensure patient safety and comfort. Thus, monitoring weight serves as a practical measure for evaluating the patient's fluid balance and the overall efficacy of the dialysis procedure.
