quot;Renal" means related to the kidneys. "Acute" means sudden. So acute renal failure means the kidneys have failed suddenly, often due to a toxin (a drug allergy or poison) or severe blood loss or trauma. Dialysis is used to clean the blood and give the kidneys a rest. If the cause is treated, the kidneys may be able to recover some or all of their function.

A sudden serious drop in blood flow to the kidneys. The most common causes of low blood flow are severe blood loss, severe infection (sepsis), a serious injury, and dehydration. Most cases of acute renal failure result from reduced blood flow. Damage to the kidneys. Certain medicines, poisons, or infection can damage the kidneys.

Your doctor will ask questions about your health to find out what medicines you have been taking, what tests you have had, and what symptoms you have noticed. The types of symptoms can help point to the cause of your kidney problem. Your doctor will do blood and urine tests that check how well your kidneys are working. These include blood urea nitrogen (BUN), serum creatinine, complete blood count (CBC), and a urinalysis.

Acute renal failure (ARF) is the sudden loss of kidney function. The body retains fluid and harmful waste builds up. A person with acute renal failure often requires hemodialysis while the cause of the problem is being found and/or treated. Some causes of acute renal failure can be corrected and the kidneys begin working again.

Renal failure means that the kidneys are not working to remove toxins from your pet's body. Your pet can be alive and be in renal failure. Most of the time, the symptoms of renal failure are decreased appetite, lethargy, vomiting, maybe diarrhea; increased water consumption, increased or decreased urine production. In cats that use a litter box, you may notice a need to change the box more often than usual. Dogs may ask to go outside more often or the well housebroken dog may have accidents.

Hyperparathyroidism occurs in most dogs and cats with chronic renal failure. Its extent is proportional to the increases of serum creatinine, and is quite directly related to the extent of uremic hyperphosphatemia. Serum phosphorus (Pi) is elevated primarily because of failure of renal excretion but its level is also affected by dietary intake, use of intestinal phosphorus binders and to some degree by the extent of PTH-mediated bone resorption.

The current state of knowledge of calcitriol-PTH relationships allows better interpretation of the classical views that the genesis of hyperparathyroidism in chronic renal failure is due to (a) hypocalcemia, (b) increased skeletal resistance to PTH, and/or (c) increased parathyroid gland set point for calcium suppression of PTH secretion.

Drugs eliminated by non-renal routes – INH, Rifampicin, Pyrazinamide and Thioamides may be given in normal doses.

In chronic renal failure serum total calcium may be within the reference range. However, this does not ensure that alterations in calcium metabolism are not present. Commonly in renal failure due to loss of functional renal tissue, calcitriol is inadequately produced. Calcitriol is important in the regulation of ionized calcium concentration. This deficient calcitriol production allows the serum ionized calcium concentration to fall, which stimulates the production of parathyroid hormone (PTH).

Toxicity of high blood levels of parathyroid hormone (PTH) generated secondary to renal disease has been revealed during the past 20 years by over 130 published studies. The concept that elevated levels of PTH are important in uremic toxicity is now so well accepted that an entire chapter in a modern nephrology textbook is devoted to the many toxic effects of excessive PTH. A partial list of some papers on PTH toxicity is appended to this presentation.

Chronic renal failure (CRF) is the slow and progressive loss of kidney function over several years, often resulting in permanent kidney failure.

This type of tests provides information on the glomerular and tubular function of the kidneys. The kidney tubules' main function is to excrete waste products while reabsorbing water and dissolved chemicals from the ultrafiltrate.

People with kidney disorders, kidney disease, or renal failure may want to consult their health practitioner about consuming potassium-dense foods like BarleyLife. According to nutritional analysis, there are 214 mg of potassium in one tablespoon (5-gram serving) of BarleyLife. Some people with kidney disease have to be careful about their potassium consumption because their kidneys may not be able to efficiently process high amounts of potassium, which may compound their problem.

It is essential to consult your doctor first and get written approval before going on our program particularly if you have a protein or fluid restriction.

Urea is considered to penetrate the epidermis, re-hydrating it. However, if penetration continued as far as the dermis, systematic absorption into blood vessels is a theoretical possibility. Patients with chronic renal failure are already at risk from increased levels of Urea in the blood causing uraemia (a toxic build up in levels of Urea in the blood). Although the risk is theoretical, as there are no reported cases we recommend erring on the side of caution.

It was once believed that high protein diets "wore out" the kidneys. This is now known to be untrue. Cats that do not have renal disease could handle high protein diets without any potential harm, while a cat that does have pre-existing renal disease should consult with a veterinarian for specific treatment.
