Hemodialysis - English Definition & Meaning

Definition

Hemodialysis is a medical procedure used to filter waste and excess fluid from the blood when the kidneys aren't working properly. It involves diverting blood to a machine that cleans it before returning it to the body. Think of it like a sophisticated water filter for your blood, removing impurities that build up. The process usually takes several hours and is performed multiple times a week. Unlike a kidney transplant, hemodialysis doesn't cure kidney failure but helps manage it. Without it, toxins would accumulate, causing severe health problems.

Etymology

The word 'hemodialysis' combines three roots. 'Hemo-' comes from the Greek 'haima,' meaning 'blood.' 'Dia-' means 'through' or 'apart,' also from Greek. 'Lysis' comes from Greek 'lysis,' meaning 'a loosening' or 'dissolution.' Thus, hemodialysis literally means 'separating blood,' referring to the separation of waste products from the blood. It first appeared in scientific literature in the mid-20th century when the procedure was developed.
