Under normal conditions, the renal always does its job perfectly, that filter the blood of metabolic wastes. However, sometimes the rentals fail to do its job, then the condition is called renal failure, as a result of dangerous substances, it accumulates in the body so that it will cause the various symptoms of renal failure.
Without treatment or proper handling, kidney failure will result in the buildup of toxins, extra fluids and harmful minerals in the blood that will eventually lead to death.
Normal Kidney Function
The kidney is a pair of bean-shaped organs, each roughly fist-sized, which is located at the rear of the upper abdomen on either side of the spine.
Under normal conditions, the kidney function is cleaning up the blood of waste products and throw it into the urine. The kidneys also serve to balance the elements of essential minerals, such as sodium and potassium, as well as producing the hormones needed to regulate blood pressure and the production of red blood cells.
What is Kidney Failure?
Kidney failure is a non-specific term which describes a decline in kidney function as above. If at any stage of kidney screening process is blocked, either because of kidney damage (e.g. due to diabetes) or by indirect obstruction (such as by a kidney stone), then it can lead to kidney failure.
There are two main types of kidney failure, acute kidney failure and namely of Chronicle. Acute renal failure (ARF) occurs when the kidney suddenly ceases to filter out waste products from the blood. Whereas, Chronic Renal Failure (CRF) develops slowly and fade a little with heavy symptoms in its early stages. To tell the difference, please read: Acute vs. Chronic renal failure
Symptoms of kidney failure will vary depending on the severity of the (stadium), progressiveness and its causes. Symptoms of acute renal failure include:
- Fluid retention
- Internal bleeding
Whereas in chronic kidney failure, a person may not have any symptoms until kidney function decreases to live 20 percent or less. In these conditions, a variety of symptoms or signs may appear, such as:
- Urine test abnormal
- High blood pressure
- Weight loss
- Loss of appetite
- Metallic taste on the tongue
- Shortness of breath
- Chest pain
- Numbness and tingling
- Easy bruising
- Decreased urine output
- Muscle twitch and cramps
- Bone porous
- Bleeding in the intestinal tract
- Brownish yellow
- Excess fluid
- Sleep disorders
To diagnose renal failure, in addition to conducting the physical examination, the doctor also requires supporting laboratory examination to confirm the suspicion. The most common blood test used IE test levels of creatinine. Creatinine is normal molecules that are found in muscles. The renal, when functioning normally, must remove creatinine from blood and throw it into the urine.
However, when the patient has renal failure at a certain level, it will have an increase in serum creatinine or in other words creatinin accumulates in the blood. This is often the first sign of kidney failure and may occur even before patients feel pain.
Kidney failure has a variety of causes, depending on the type. Further please read: causes renal failure
Treatment of acute renal failure (ARF)
Most, the kidneys will recover at least some of its functions if the underlying cause is resolved. In some cases, acute kidney failure occurs so severely that dialysis (washing the blood) with artificial kidney machine is required. Further please read: acute renal failure
Treatment of chronic renal failure (CRF)
As in the ARF, the underlying disease must be addressed. If hypertension, then the patient should be diligent about taking medication and antihypertensive in diabetes patients should always control blood sugar. Fortunately, kidneys have a large compensation ability. Even when a patient has lost up to 80 percent of his kidney function, but does not require therapy because a small number of the remaining kidney is enough to rid the body of waste. Further please read: chronic kidney failure
However, in patients with kidney failure who so badly, then to survive there are two options: dialysis and transplantation. Dialysis can be done in one of two ways – by either hemodialysis (HD) or peritoneal dialysis (PD). HD requires that patients must be connected to a dialysis machine at home or in a dialysis center, usually three times per week.
Kidney transplantation has become the best treatment for many patients with kidney failure
