Kidney failure is diagnosed through urine and blood tests, along with radiological imaging methods. Dialysis treatment is generally considered when kidney function has been lost by 80-90%. Specifically, a decrease in the glomerular filtration rate (GFR) to below 12 mL/min or a sustained filtration capacity below 10 mL/min indicates the need for dialysis. In these advanced stages of kidney failure, patients may experience the following symptoms:
* Nausea
* Fatigue
* Loss of appetite
* Shortness of breath
* Edema-related swelling
* Sleep disturbances
