What do they do?• Remove waste products and extra fluid
fromthe blood by forming urine
• Keep blood chemicals in balance• Produce some of the body’s hormones to
control anemia, blood pressure, and bonehealth

Causes ??? Diabetes and high blood pressure are theleading causes of chronic kidney disease Other conditions that may cause chronic
kidney disease• Glomerulonephritis• Genetic diseases (e.g. polycystic kidney
disease)• Inflammatory conditions (e.g. lupus)• Obstruction to the urinary tract• Repeat urinary tract infections

Starting to feel it …..• Waste products and fluid build up in the blood causing a condition called uremia.
• Symptoms of uremia include:• Swelling (face, hands, feet)• Shortness of breath• Itching• Poor appetite• Nausea and vomiting• Trouble concentrating

Diet with CKD – Early StagesProtein: To restrict or not to restrict?For persons in stages, 1, 2,3 – protein intake
is often limited to 12-15% of each day’s calorie intake or to .8 grams/kg body weight.
Persons with Stage 4 CKD may be advised to reduce protein to 10% of calorie intake each day, which is .6-.75 grams protein/kg body weight.

PhosphorusPhosphorus restriction is recommended as
soon as an elevated blood level is seenSome experts think 800-1000mg of
phosphorus daily is adequate

PotassiumIf the level is high, a low potassium diet is
prescribed. Restricting such foods as avocados, dried fruits (raisins, apricots, prunes), potatoes, oranges, bananas, and salt substitutes is often needed.

Treatment for Stage 5A treatment for Stage 5 kidney disease• Blood is cleaned through filtration• a natural filter inside the body (peritoneal
dialysis)• an artificial filter outside of the body
(hemodialysis)• Dialysis must be done on a regular basis toreplace kidney function

Peritoneal Dialysis• Removes wastes and fluid• Catheter in the abdomen• Several exchanges daily

Hemodialysis• Blood circulates through a filter (dialyzer)
toremove wastes and fluid• A machine controls speed and safety factors• Hemodialysis can be done in-center or at
home, night or day• Traditional: At a dialysis facility• 3 treatments/week week 3 to 4 hours each
tr• Option for self-care and nocturnalhemodialysis
