The Basics On Chronic Renal Failure

By Matthew Fletcher


The kidneys are necessary organs, meaning that if they fail to operate properly we'll not be able to live through. You'll find 5 stages of kidney damage, categorized by lowering filtering potential of the kidneys. The ultimate or 5th stage is known as chronic renal failure and once this stage is achieved if serious medical treatment is not introduced, we can no longer live. One of the main activities of the kidneys is to clear away the body of toxins or unnecessary matter. When this operation does not occur proficiently these levels increase in the blood triggering toxicity and illness. Unfortunately this can last for a long period and kidney function can become quite diminished before symptoms take place and we are informed to a trouble with kidney function. This is why, an individual may move to the recent stages of kidney disease before they are aware that they are sick.

The filtering power of the kidneys is referred to as the glomerular filtration rate (GFR) and this provides us a total sign of kidney operation, and is the reading used to suggest the amount of kidney damage, which runs as follows: Stage 1 GFR 90 Suggests minor kidney damage or normal filtering; Stage 2 GFR 60-89 Suggests a light decline in kidney function; Stage 3 GFR 30-59 Implies a reasonable decrease in kidney work which is known as early kidney failure; Stage 4 GFR 15-29 Implies an intense decrease in kidney function; Stage 5 GFR 14 or below reveals kidney failure or End Stage Renal Disease (ESRD). This can also be regarded as chronic renal failure.

Even though it will take quite a while for signs and symptoms of kidney damage to show up, when the stage of chronic renal failure is reached, you will find certainly many symptoms that are going to occur. These could vary between individuals according to other medical issues, but the most usual signs and symptoms include; high blood pressure level, fluid retention, fatigue, lack of appetite, anemia, headaches, itchy skin and urinary changes like foamy urine and unwanted urination throughout the night. Kidney performance can be assessed by making use of blood and urine samples that evaluate different factors of kidney operation. A combination of various results is the best way to measure the overall filtering potential of the kidneys, which will verify when treatment is required. The kidneys are in charge for filtering the unwanted quantities of several nutrients from our blood and when this is not occurring properly as shown via blood tests, making dietary changes can go a long way in taking the burden off kidneys in chronic renal failure, thereby lessening the advancement of disease.

The most familiar measurements used to assess chronic renal failure include; GFR, creatinine and BUN along with nutrient amounts of potassium, phosphorus and sodium. You can find also other factors thought about but for the sake of this discussion these are the most significant figures to be thought of as. As described earlier GFR provides the best hint of the filtering power of the kidneys and it performs inversely with creatinine. Creatinine is a product of skeletal muscle metabolism and is eliminated from the body via urine when kidneys are filtering proficiently. Therefore high creatinine implies a trouble with kidney filtering ability. BUN means blood urea nitrogen. It is a blood test that measures the condition of nitrogen in the blood, which is formed from a waste product called urea. Urea is made of the breakdown of protein and should also be taken out of the body through the urine. Therefore when the kidneys are not performing correctly as observed in chronic renal failure, BUN results increases dramatically.

Urine tests are also helpful to screen for protein. In healthy kidneys when the filtration units are functioning well, no protein can be found in the urine. However in kidney damage, in which the structure of these units is influenced, protein particles can leak through into the urine where they could then be detected. At this point dietary proteins should be restricted to slow the growth of chronic renal failure.
