Define kidney failure | occurs when your body looses the ability to sufficiently filter waste from your blood |
3 Symptoms of kidney failure | poor appetite, decreased urine output, tired, trouble sleeping, fluid retention (swelling in ankles/feet/legs), shortness of breath, fatigue, irregular heartbeat |
Factors that contribute to Kidney failure | 1. diabetes
2. heart disease
3. High blood pressure |
What is kidney dialysis? | The process that removes excess water, solutes and toxins from the blood from people whose kidneys cannot function normally |
What are components of dialysis fluid? | purified water
electrolytes
glucose |
why should dialysis fluid and blood be close to/ the same concentration ? | So there is no net movement of glucose out of the blood by diffusion. |
How does kidney dialysis work? | Tube is surrounded by dialysis fluid that has the same concentration of normal blood
Any excess substance in the blood (urea, salts) will diffuse out
Dialysis fluid leaving the machine will be rich in salts and body wastes like urea |
What is a graft? | Healthy transplanted kidney |
What should someone undergo to see if their kidney is eligible for transplantation? | Urine/ blood tests
x rays
MRI's |
What is the relationship between diabetes and kidney disease? | Overtime levels of sugar in the blood damages the filtering units within each kidney |
What is the relationship between high blood pressure and kidney failure? | HBP can cause arteries around the kidneys to narrow/weaken/harden
damaged arteries might not be able to deliver enough blood to the kidney |
What is the relationship between heart disease and kidney failure? | When the heart is no longer pumping blood efficiently it become congested with blood causing pressure to build up in the main vein connected to the kidneys and leading to congestion in the kidneys too |
