By combining diffusion and filtration processes hemodiafiltration is more efficiant then hemodialysis, enabling the removal of both smaller and larger waste molecules, leading to a more comprehensive blood purification and improved chemical balance.

Benefits include improved elimination of toxins and excess fluid, leading to a better quality of life for the patient. There are some potential risks, such as infection and vascular access complications.

Preparing for hemodiafiltration involves establishing vascular access and following specialist's instructions regarding dietary adjustments, medication, and lifestyle changes to ensure optimal treatment results and minimize complications.
