A new advanced treatment option is now available for dialysis patients under Durham Nephrology's care. South Durham and West Pettigrew dialysis units now include hemodiafiltration (HDF), a step forward in how toxins are filtered from the blood during treatment.
HDF combines standard hemodialysis with an added filtration process. In addition to removing waste through diffusion like traditional dialysis, HDF uses pressure to push blood through the dialyzer, clearing more middle-sized toxins and excess fluid, a process called convection.
Patients receiving HDF may experience benefits over time, including reduced inflammation, fewer muscle cramps, improved blood pressure control, and better long-term heart health.
To understand more about HDF, talk with your dialysis care team, or contact Durham Nephrology at 919-477-3005.
