Although the term "uremia" literally means the presence of urea (and other nitrogen-containing wastes) in the blood, it is actually the complex terminal stage of kidney failure.
Causes & Development
Uremia can also be caused by NSAIDs, especially in older patients who are being treated primarily with ibuprofen for arthritis.
Signs & Symptoms
Some of the early signs include lethargy, mental depression, loss of appetite, and edema; later symptoms include diarrhea, anemia, convulsions, coma, and a gray-brown coloration.
Treatment & Prevention
Treatment of uremia, which is directed at the underlying kidney disease, is usually with dialysis and renal transplantation.

GLOSSARY
Anemia (Anaemia, Anemias)
A condition resulting from an unusually low number of red blood cells or too little hemoglobin in the red blood cells. The most common type is iron-deficiency anemia in which the red blood cells are reduced in size and number, and hemoglobin levels are low. Clinical symptoms include shortness of breath, lethargy and heart palpitations.
Arthritis (Arthritic)
Inflammation of a joint, usually accompanied by pain, swelling, and stiffness, and resulting from infection, trauma, degenerative changes, metabolic disturbances, or other causes. It occurs in various forms, such as bacterial arthritis, osteoarthritis, or rheumatoid arthritis. Osteoarthritis, the most common form, is characterized by a gradual loss of cartilage and often an overgrowth of bone at the joints.
Chronic Renal Failure (Chronic Renal Insufficiency, Kidney Failure, Renal Insufficiency)
(CRF) Irreversible, progressive impaired kidney function. The early stage, when the kidneys no longer function properly but do not yet require dialysis, is known as Chronic Renal Insufficiency (CRI). CRI can be difficult to diagnose, as symptoms are not usually apparent until kidney disease has progressed significantly. Common symptoms include a frequent need to urinate and swelling, as well as possible anemia, fatigue, weakness, headaches and loss of appetite. As the disease progresses, other symptoms such as nausea, vomiting, bad breath and itchy skin may develop as toxic metabolites, normally filtered out of the blood by the kidneys, build up to harmful levels. Over time (up to 10 or 20 years), CRF generally progresses from CRI to End-Stage Renal Disease (ESRD, also known as Kidney Failure). Patients with ESRD no longer have kidney function adequate to sustain life and require dialysis or kidney transplantation. Without proper treatment, ESRD is fatal.
Dialysis
The artificial process of cleaning wastes from the blood when kidneys fail.
Diarrhea
Excessive discharge of contents of bowel.
Edema
Abnormal accumulation of fluids within tissues resulting in swelling.
Kidneys (Kidney, Renal)
Bean-shaped organs, each about the size of a fist. They are located near the middle of the back, just below the rib cage. The kidneys are sophisticated reprocessing machines, each day handling about 50 gallons of blood to sift out about half a gallon of waste products and extra water. The waste and extra water become urine, which flows to the bladder through tubes called ureters. The actual filtering occurs in tiny units inside the kidneys called nephrons. Every kidney has about a million nephrons. In a nephron, a glomerulus -- which is a tiny blood vessel, or capillary -- intertwines with a tiny urine-collecting tube called a tubule. A complicated chemical exchange takes place, as waste materials and water leave your blood and enter your urinary system. The kidneys recycle chemicals such as sodium, phosphorus, and potassium and thus regulate their levels. Renal: Pertaining to the kidneys.
NSAID (NSAIDs)
Non-steroidal anti-inflammatory drug.
Uremia
Condition characterized by excessive urea and other nitrogen compounds in the blood due to renal insufficiency.
