Healthy kidneys work 24 hours a day, 7 days a week. Dialysis replaces only a small amount of your kidney function. If you are not getting adequate dialysis, you will start to have symptoms of kidney failure, such as:

• Metallic taste in your mouth
• Fatigue
• Itching
• Loss of appetite

Your doctor may prescribe a larger dialysis machine, longer treatments or both to be sure you get as much dialysis as you need to feel good and keep doing the things you enjoy.
