Why is urea in the blood increased? Urea in urine.

Urea is the final product of the breakdown of proteins. It is excreted from the body through the kidneys. The work of the kidneys is analyzed by the amount of urea in the blood and in the urine. If urea in the blood is increased, then you can talk about acute and chronic kidney disease. Due to insufficient work of the body, urea accumulates in the blood. Consequently, its urinary index decreases.

Protein metabolism in the body is a rather complex process in which one part of the proteins undergoes disintegration, the other forms a new form. The decomposition of proteins is accompanied by the release of a toxic substance - ammonia. Urea is formed from ammonia in the liver. Then it is excreted in the urine through the kidneys. The excretory capacity of the kidneys can be judged by the concentration of urea in the blood and the rate of its excretion from the body. By the factor of synthesizing the component in the liver, reducing it in the blood suggests a liver disease. This can be cirrhosis.

Proteins in the human body are contained, mainly in the muscles. If the process of protein breakdown in muscles accelerates, then urea in the blood is increased. Its indicator characterizes the work of muscles, liver, kidneys. The concentration is determined by a biochemical blood test in a laboratory. For this, blood is taken from the vein in the morning hours, on an empty stomach.

Even if urea in the blood is increased, it does not always indicate the presence of any disease. The indicator can also increase in perfectly healthy people who eat, mainly foods rich in protein: meat, legumes. In addition, physical activity gives the same effect.

Diseases in which urea in the blood is increased

The concentration of urea in the blood increases as a result of the following diseases: pyelonephritis, glomerulonephritis, amyloidosis of the kidneys. On the disease of the body, the symptoms are indicated: a violation of urination, increased blood pressure, fatigue, general weakness, traces of blood in the urine. Analysis shows that urea is increased. In addition, in diseases that result in impaired blood access to the kidneys, urea in the blood is also increased. Deviation of the component from the norm may occur due to heart failure, high degree of burns, bleeding. The pathology is caused by incomplete purification of the blood by the kidneys. Such diseases as tumors, thyrotoxicosis affect the increase in the breakdown of proteins, and consequently, the increase in urea.

Urea in urine

By the content of urea in urine, one can judge the cause of its increase in blood. If the performed analysis did not reveal deviations from the norm, then urea in the blood is increased not because of kidney disease, but because of a violation of blood flow to the organs (kidneys). Such a factor indicates other diseases, perhaps, the heart. Decreased urea in the urine indicates kidney disease.

Urea in urine is obtained by laboratory method. For analysis, it is required to collect a daily dose. During the collection period, you should use liquid as usual. The adoption of meat products - to limit. With an increase in the breakdown of proteins, the urea index in the urine increases. Pathology occurs with the following factors: a large amount of protein coming from food; Hormonal failure of the thyroid gland; Postoperative condition.

Reduction of urea in urine occurs in children, vegetarians, pregnant women, in people in the postoperative period. Diseases that lead to a decrease in urea in the urine are: cirrhosis, hepatitis, malignant liver tumors, kidney failure, pyelonephritis.

In order to preserve one's own health, it is necessary to periodically examine blood and urine. If there is a change in the urea index, you should immediately contact a specialist. Increase or decrease of urea in blood and urine indicates the presence of diseases of several organs. An accurate diagnosis is needed, which establishes the main cause, which led to pathology. With properly prescribed treatment, the test results are normalized.
