kidney failure
The kidneys are one of those organs that play a very important role in the human body and have as their main task the regulation of the chemical homeostasis of the whole organism. If the kidneys are not working very well and their functioning can hardly be called satisfactory, the development of kidney failure is a very likely scenario.
If we speak in more familiar words for the common man, then we are talking about kidney failure: symptoms of kidney failure. This ailment is very dangerous due to the fact that it can occur unexpectedly or manifest itself only after a while. In the first case, we are talking about acute renal failure, and in the second - about chronic.
Characteristic features of acute and chronic renal failure
The main difference between acute and chronic renal failure is the period that passes before the onset of symptoms.
With acute renal failure, this process occurs no later than within a few days. In this case, we are talking about a reversible process that has an ischemic or toxic genesis. 
This condition is the result of a water disorder, electrolyte, osmotic or acid-base balance. Kidney failure: The symptoms of acute kidney failure can be the cause of severe violations of renal blood flow, which leads to the retention of nitrogenous products in the human body.
Renal disorders can also lead to kidney failure, due to a sharp drop in the number of functioning nephrons. In this case, we are talking about HPN. An unfortunate consequence of such a state , they are signs of kidney failure in humans- self-poisoning of the body due to the accumulation of products of its own vital activity. The gradual appearance of symptoms of a chronic disease only complicates the problem of diagnosis and treatment, because for some time the entire load falls on the healthy tissues of the organ, which are also destroyed over time. The end stage of kidney failure is complete kidney failure.
The reasons
Kidney failure causes are directly related to certain forms, among which are the following:
A burn injury or an excess of potassium in the blood can also contribute to this pathology. Long-term digestive disturbances (such as vomiting and diarrhea) can lead to dehydration, which can lead to kidney failure. We must not forget that such a deviation can develop in the fetus inside the womb or immediately after the process of birth in a newborn.
Symptoms of Kidney Failure
Kidney failure is called a pathological condition, the consequence of which is a violation of excretion from the body and the formation of urine. This disease can be recognized by a number of signs. Firstly, we are talking about the complete or partial cessation of urine output. A sharp decrease in diuresis is also possible. Secondly, swelling appears on the face and ankles. Because of this, body weight can increase dramatically. 
All these symptomskidney failure in humansclosely associated with the occurrence of feelings of nausea, vomiting, loss of appetite. Depending on the human body, weakness or malaise, abdominal pain, and itchy skin may occur. A characteristic sign that speaks of kidney failure: the symptoms of kidney failure is the presence of traces of blood in the urine. If the appropriate kidney failure treatment is not organized in time, the patient will face such unpleasant symptoms as drowsiness, shortness of breath, confusion.
All this is due to the accumulation of fluid. On the body, the appearance of hematomas or even open bleeding is likely. Additional symptoms are fainting, coma, spastic muscle contractions.
Kidney failure in a chronic form is accompanied by polyuria, frequent nocturnal urination, a significant deterioration in well-being, edema, shortness of breath, nausea, vomiting, and loss of appetite. Moreover, the patient often notices pain in the bones and chest area, his skin becomes pale. Women often develop amenorrhea, "uremic frost."
Consequences of kidney failure
As a result of failure of the kidney consequences most often occurs necrosis of the renal cortex. This condition is nothing else, as a consequence of a sufficiently long violation of the process of renal circulation. Stagnation of blood often leads to the development of edema. Pathology is very closely related to the likelihood of infection in the kidneys.
The chronic form of the disease is associated with more serious consequences due to the accumulation of uremic toxins in the body. First of all, it affects the state of the nervous system and leads to the occurrence of convulsive conditions, damage to the mental function.
Another characteristic feature of kidney failure is the development of anemia. This consequence occurs due to a decrease in the level of formation of erythropoietin. Hematological disorders lead to impaired phagocytic and immune function of leukocytes. This fact increases the likelihood of developing concomitant infections.
The consequences of kidney failure are also complications arising from the cardiovascular system. We are talking about hypertension, but the risk of provoking strokes or myocardial infarction is much worse.
Kidney failure also affects the strength of human bones. The result of the disease can be osteodystrophy. If we talk about the gastrointestinal tract, then it is worth noting such consequences as weight loss with the likelihood of anorexia. Moreover, bleeding in the gastrointestinal tract may occur. Associated problems are metabolic disorders and a decrease in the amount of hormones produced. The latter almost always causes a sharp decline in fertility.
Can they earn
People with such a diagnosis often wonder if they can earn kidneys after a refusal. It all depends on the stage at which it was detected and on the measures taken by the doctor and the patient. The main thing is to stop delaying visiting specialists, and as soon as possible and quickly contact the nearest medical institution for help.
