Azotemia - what is it? Description, symptoms and therapy

Azotemia - what is it? Increased presence in the human blood of nitrogen-containing products, which are formed after protein processing. This indicates a developing kidney failure.

Characteristics of the disease

Azotemia - what is it? This disease is directly related to the kidneys. They reduce the rate of glomerular filtration. In the blood, the concentration of residual nitrogen, indicator, amino acids, etc. is increased. The index of proportions of nitrogen, creatinine and urea is increasing.

When the kidneys are working in normal mode, the ratio of the listed elements does not exceed 15 units. Nitrogen products are excreted in the urine. If the kidneys work is broken, active protein catabolism begins, the whole system fails.

Types of azotemia

Azotemia - what is it? The disease is divided into three types. Prerenal azotemia begins after a reduction in cardiac output. The kidneys are not receiving blood. Prerenal azotemia occurs due to heart failure, dehydration, reduced blood circulation, shock and for many other reasons. When the index exceeds the 15 mark, the reason lies in the failure of the filtration of creatinine and nitrogen. GFR decreases due to hypoperfusion. This leads to an increase in the level of creatinine and nitrogen. After reabsorption, its quantity rapidly grows.

The second type of azotemia is renal. Most often it leads to uremia. Usually, this condition occurs due to kidney disease or parenchymal damage. Renal azatemia causes the development of the following:

• glomerulonephritis;
• kidney failure;
• acute tubular necrosis, etc.

With this form of azotemia, the index is less than 15. GFR decreases, blood levels of nitrogen and creatinine are increased. Reabsorption does not occur due to damage to the proximal tubules. Nitrogen is excreted from the body together with urine.

The third type of azotemia is postrenal. In this case, the obstacle to the standard urine output is below the kidneys. The causes may be congenital abnormalities:

• hyperplasia of the prostate;
• vesicoureteral reflux;
• is a tumor that compresses the urethra;
• pregnancy;
• stones in the ureter.

As a result, it is possible to develop hydronephrosis due to resistance to normal urine outflow. At the same time, the index is higher than 15. The pressure in the nephron increases, which causes active nitrogen reabsorption. Accordingly, it increases in the index.

Symptoms of the disease

One of the infrequent diseases is azotemia. Symptoms begin to progress as the pathology proceeds. The main signs of azotemia are:

• pallor of the skin;
• oliguria( decreased diuresis);
• permanent dry mouth;
• thirst;
• galloping blood pressure;
• swelling;
• uremia;
• tachycardia;
• general weakness.

During illness can be observed:

• lack of appetite;
• nausea;
• vomiting;
• dry and coated tongue;
• indigestion;
• anemia;
• smells of ammonia from the mouth;
• profuse diarrhea;
• development of enterocolitis, stomatitis and gingivitis;
• calf convulsions;
• depression;
• sharp apathy, alternating with restless states;
• drowsiness;
• tremor.

Additional symptoms of azotemia are pruritus and dry skin, sometimes a decrease in hearing and a drop in vision.

Diagnosis

Azotemia, the symptoms, the treatment of which is determined by diagnosis, is a complex disease. For successful therapy, you need an accurate diagnosis, as well as finding the cause that caused azotemia. Diagnosis is carried out by a nephrologist( a specialist who deals with kidney disease) and a urologist. The patient gives blood and urine tests. The patient measures the nitrogen and creatinine index.

Treatment of

Azotemia, treatment of which begins with a consultation of a urologist or nephrologist, - the disease is serious and requires careful diagnosis. After the results of the tests, therapy is prescribed. With a timely and accurate diagnosis, the disease is treated quickly and effectively. With late treatment of the patient, unwanted complications can arise, many of which are quite dangerous for health.

During therapy, hemodialysis is used. Appointed funds that eliminate the unpleasant symptoms of azotemia. There are drugs that restore normal blood pressure and improve heart function. Azotemia - what is it? The disease occurs against a background of impaired kidney function. Therefore, a lot of nitrogenous compounds accumulate in the blood, which are not removed from the body in full. Therapy is aimed at restoring the kidneys. A doctor may be prescribed a special diet. It is necessary to abandon large physical exertions at the time of treatment.

Categorically not recommended to engage in self-medication. The independent choice of medications can lead to the opposite effect - renal failure. Therefore, at the first signs of the disease, you should immediately consult a doctor.

Prevention

For the prevention of azotemia, it is necessary to constantly maintain the immune system, do gymnastics, play sports and go for a walk in the fresh air. Time is definitely allocated for a good rest. It is necessary to avoid hypothermia and to treat any diseases associated with the kidneys in time.

Forecast

An unfavorable prognosis for the treatment of azotemia is raised only if there is no correct and timely treatment. With late referral to the doctor the disease is already actively progressing, there are additional complications, which complicates therapy. With timely access to a doctor, the treatment of azotemia has a favorable prognosis. Complex therapy cures the symptoms and normalizes the urinary system.
