Calcium: The most common mineral in your body. Calcium is essential for healthy bones and teeth. It is also important for regulating heart function, blood clotting, and muscle functioning, such as contraction and relaxation. Calcium levels are often abnormal in people with kidney disease. Raised calcium levels may cause headaches, nausea, sore eyes, aching teeth, itchy skin, mood changes, and confusion.
Cannulation: Putting in the needles for dialysis.
Carbohydrate: A macronutrient. Carbohydrates are the body’s main energy source and come from mostly grain foods, fruit, vegetables and dairy products. Sugar is also a type of carbohydrate but should be limited from the diet.
Cardiovascular disease: Includes all disease and condition of the heart and blood vessels, such as arteries and veins. The most common conditions include heart attack, heart failure, stroke, blockages in the blood vessels and vascular kidney disease.
Carrier: A person who has a change in one copy of a gene. Every person carries two copies of most genes (one copy from the mother and one from the father). The carrier does not have the genetic disease related to the abnormal gene, but they can pass this abnormal gene to their child.
Catheter: A plastic tube that is used to take fluid in or out of your body (see vascular access catheter).
Central nervous system: Your brain and spinal cord.
Central venous catheter: A special tube that is surgically inserted into your neck, collarbone or top of your leg to allow temporary access for haemodialysis.
Cholesterol: A naturally occurring, waxy substance made by the body. It is an essential building block of cell membranes, hormones and vitamin D. See HDL cholesterol, LDL cholesterol.
Chronic kidney disease (CKD): A progressive reduction in kidney function or kidney damage which is present for at least three months. A term used widely to describe kidney damage or reduced kidney function (irrespective of the cause) that persists for more than three months. Sometimes CKD leads to kidney failure, which requires dialysis or a kidney transplant to keep you alive.
Chronic rejection: Where your body gradually rejects your transplanted kidney in the months and years after your transplant.
Cold ischaemia time: The time between when the kidney is removed from your donor and transplanted into your body.
Collagen: The main protein in your skin, which gives strength and support for your tendons, cartilage, bone and connective tissue which surround many of your organs.
Compatible: When a donor’s blood type is a good match to the recipient’s blood type.
Compatibility: An assessment of whether your body will accept the transplanted kidney.
Computed tomography: An imaging procedure that uses special x-ray equipment to create a series of detailed pictures or scans of areas inside your body.
Confidentiality: When someone’s personal information is kept private.
Continuous Ambulatory Peritoneal Dialysis (CAPD): A type of dialysis where a special fluid is put into the peritoneal cavity (abdomen) through a soft, plastic tube (catheter) then drained out a few hours later. This is usually done 3 or 4 times during the day.
Constipation: Bowel movements that are infrequent or hard to pass.
Corticosteroids: Medications that inhibit the body’s immune response and are often used to treat a range of conditions including inflammation.
Cross match: A test that combines your blood cells with the blood cells from the donor. A positive reaction means that there is a likelihood of severe rejections of the donor kidney.
Creatinine: Waste that is produced by the muscles. It is usually removed from your blood by your kidneys and passes out in your urine (wee). When your kidneys aren’t working properly, creatinine stays in your blood.
Cycler: A machine that connects to a catheter and performs the exchanges overnight during automated peritoneal dialysis.
Cyst: A sack full of fluid.
Cystine: Made from proteins found in a wide range of foods including meat, eggs and dairy foods.
Cystitis: A urinary infection of the bladder. Cystitis is the most common type of urinary infection.
Cystoscopy: An investigation where a special viewing camera is inserted via the urethra into the bladder.
Cytotoxic antibodies: Antibodies that your body develops to prevent infections.
