Use of water in dialysis and its impact on the environment

Curr Opin Nephrol Hypertens. 2025 Mar 1;34(2):151-155. doi: 10.1097/MNH.0000000000001058. Epub 2024 Dec 17.

Abstract

Purpose of review: The climate crisis poses significant challenges across various sectors, including healthcare, where resource consumption often exacerbates environmental issues. This review addresses concerns over current levels of water use for dialysis treatment, a critical procedure for patients with kidney failure. Despite its life-saving importance, the dialysis process consumes large quantities of water, contributing to water scarcity and increased carbon emissions associated with water treatment and distribution.

Recent findings: Through a comprehensive analysis of current practices, we identify inefficiencies and propose sustainable alternatives aimed at reducing water usage in dialysis.

Summary: Findings indicate that optimizing treatment protocols and considering innovative technologies can significantly mitigate the environmental impact while maintaining patient care standards. This review underscores the urgent need for the healthcare sector to adopt sustainable practices in response to the climate crisis.
