Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly. It often involves diverting blood to a machine to be cleaned.
Dialysis is a treatment that does some of the things done by healthy kidneys. It is needed when your own kidneys can no longer take care of your body's needs.
An endoscopy is a test to look inside your body. A long, thin tube with a small camera inside, called an endoscope, is passed into your body through a natural opening such as your mouth. Your GP may refer you for an endoscopy if you're having certain symptoms. It will usually be done at an endoscopy unit in a hospital.
You should not experience any pain during the endoscopy, but it may be quite uncomfortable. You will also be offered some sedation, which may help you to relax and may make everything more comfortable throughout. These procedures can take between 15 minutes and 1 hour, and you will be monitored throughout.
