bladder: The balloon-shaped organ inside the pelvis that holds urine.
Blood Pressure: Your heart pumps blood through tubes called arteries and veins. The pumped blood makes pressure inside your arteries. This is called blood pressure. When your blood pressure is checked, it tells how hard your heart is working to pump your blood. For people with diabetes, a normal blood pressure is less than 130/80.2

Diabetic Nephropathy: The medical name for kidney disease caused by diabetes.
Dialysis (dy-AL-ih-sis): A way of cleaning waste and extra fluid from the blood once the kidneys have failed. There are two types of dialysis: hemodialysis and peritoneal dialysis.
- hemodialysis (HEE-moh-dy-AL-ih-sis): The use of a machine to clean wastes from the blood after the kidneys have failed. The blood travels through tubes to a dialyzer, which removes wastes and extra fluid. The cleaned blood then flows through another set of tubes back into the body.
- peritoneal (PEH-rih-tuh-NEE-ul) dialysis: Cleaning the blood by using the lining of the abdominal cavity as a filter. A cleansing liquid, called dialysis solution, is drained from a bag into the abdomen. Fluids and wastes flow through the lining of the cavity and remain “trapped” in the dialysis solution. The solution is then drained from the abdomen, removing the extra fluids and wastes from the body. There are two main types of peritoneal dialysis:
- continuous ambulatory (AM-byoo-luh-TOH-ree) peritoneal dialysis (CAPD): The most common type of peritoneal dialysis. It needs no machine. With CAPD, the blood is always being cleaned. The dialysis solution passes from a plastic bag through the catheter and into the abdomen. The solution stays in the abdomen with the catheter sealed. After several hours, the person using CAPD drains the solution back into a disposable bag. Then the person refills the abdomen with fresh solution through the same catheter, to begin the cleaning process again.
- continuous cycling peritoneal dialysis (CCPD): A form of peritoneal dialysis that uses a machine. This machine automatically fills and drains the dialysis solution from the abdomen. A typical CCPD schedule involves three to five exchanges during the night while the person sleeps. During the day, the person using CCPD performs one exchange with a dwell time that lasts the entire day.
dialysis solution: A cleansing liquid used in the two major forms of dialysis’hemodialysis and peritoneal dialysis. Dialysis solution contains dextrose (a sugar) and other chemicals similar to those in the body. Dextrose draws wastes and extra fluid from the body into the dialysis solution.

Glomerular (gloh-MEHR-yoo-ler) filtration rate (GFR): A calculation of how efficiently the kidneys are filtering wastes from the blood. A traditional GFR calculation requires an injection into the bloodstream of a fluid that is later measured in a 24-hour urine collection. A modified GFR calculation requires only that the creatinine in a blood sample be measured. Each laboratory has its own normal range for measurements. Generally, the normal range for men is 97 to 137 mL/min/1.73 m2 of body surface area. The normal range for women is 88 to 128 mL/min/1.73 m2.
