Does dialysis strip the body of essential metals?
NCT ID NCT07808944
First seen Sep 09, 2026 · Last updated Sep 10, 2026 · Updated 1 time
Summary
Researchers measure blood levels of zinc, copper, selenium, lead, mercury and other trace elements in older adults with advanced chronic kidney disease who receive hemodialysis. The study compares levels before and after a dialysis session in patients new to treatment and in those who have used it for at least five years. It also checks whether the elemental profile changes with longer exposure to dialysis. The goal is to understand how hemodialysis and environmental factors affect these elements in the body.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If researchers map how dialysis changes trace element levels, doctors could one day adjust dialysis or supplements to correct deficiencies and avoid harmful buildups.
- What could go wrong
- This is a small pilot study of 20 older patients at one center, so its measurements may not apply to other dialysis patients or prove that dialysis itself causes any imbalance.
