What is the primary purpose of dialysis?

The primary purpose of dialysis is to temporarily reduce or remove the volume overload and high levels of waste products from the blood. This procedure is essential for patients whose kidneys are no longer able to perform these functions adequately, due to conditions such as acute or chronic kidney failure. Dialysis helps maintain fluid and electrolyte balance, preventing potentially life-threatening complications from the accumulation of toxins and excess fluids.

While it might seem beneficial to think of dialysis as a permanent solution, it is important to note that it does not cure kidney disease or restore kidney function; rather, it acts as a temporary substitute while the underlying conditions are managed or until potential kidney recovery occurs.

The procedure plays a critical role in the short-term management of patients with severe kidney impairment, allowing for the essential detoxification and fluid management that the kidneys would normally handle. It is not designed to enhance kidney functionality or provide nutritional support, which are functions outside its primary role.
