We talk about urea in agriculture but not only that, because this substance is an excellent fertilizer, but we also hear this term mentioned in discussions related to the evaluation of kidney functionality, especially when we want to understand if our body is able or not to sustain normal metabolic process avoiding excessive accumulations of nitrogen. There are physiological values to be taken into consideration and to do so it is necessary to go to analyze urea.
Urea is not a "pure" chemical element, but a chemical compound that can be observed when carrying out blood and urine tests, in the second case we speak of urinary urea. The value obtained is very important because it gives us valuable information on the health of our kidneys and their proper functioning. This molecule we are dealing with is produced by the liver and kidneys in the final phase of protein synthesis, or the urea cycle, when it is measured it is done with the idea of monitor and measure nitrogen concentrations in the blood and their impact on the main metabolic functions performed by our body.
When there is a lot of nitrogen, or when azotemia is high, blood urea concentrations exceed certain reference values.
If you want to chemically define urea it must be indicated as an amide ofcarbamic acid, it is a powder of water-soluble crystals naturally present also in the skin. It derives from the oxidation of some amino acids that are used by our body during protein synthesis and its purpose is to limit the concentrations of nitrogen in the blood because the main alterations in physiological pH.
Most of the urea is expelled through the urine and in much smaller parts even when you sweat, it should be considered a waste product, the result ofprotein metabolic activity carried out by both the liver and kidneys. It is for this reason that its concentration in the blood gives us indications regarding the correct functioning of the kidneys which filter it, favoring its expulsion. This is not a one-off activity, the kidneys do it continuously and under normal conditions blood nitrogen concentrations stabilize around 15-40 mg / dL.
When it happens that the concentrations exceed the indicated optimal values, which may vary depending on some "personal" factors, we talk about azotemia or uremia. We must not panic but in the face of high numbers we can, indeed, have a responsibility to investigate because it could be a first alarm bell of a condition of kidney failure.
It may also happen that high urea does not have a pathological origin and at that point it is enough to "settle down" change fed regime, if, on the other hand, there is a pathological factor, managing the problem becomes more difficult, the doctor consulted will tell us about this. In general, the urea rate depends on the functioning of the kidneys, the amount of protein introduced with food and the level of hydration but not always with a good diet and lots of water everything works out.
Let's see some triggering pathological causes high urea in the blood. There are long periods of fasting, dehydration, diabetes mellitus, hemolysis, the presence of bleeding, gout or situations of heart failure. Hypertension and hyperthyroidism can also be causes as well as renal neoplasia, kidney tumors, burns, a excessive consumption of protein foods. Those who have suffered trauma can have high levels of urea or those who have suffered a shock, those suffering from liver cirrhosis or those who have taken an excessive amount of cortisone and diuretic drugs.
The symptoms of the high are quite varied nitrogen concentration, not always easy to identify and above all to interpret correctly, so it is essential to consult a doctor and not proceed with the do-it-yourself. Among the most common symptoms of high blood urea are: tiredness, weight loss, vomiting, increased blood pressure, tremors, tachycardia, reduction in the amount of urine produced and paleness.
Urea: natural remedies
If there are no pathological triggers and the doctor confirms it, we can cure ourselves by adopting a correct eating style and drinking a lot. In general, it is necessary to act on one's diet by decreasing the amount of proteins of animal origin, giving up, if we have these vices both smoking and alcohol which are another cause of high blood urea. Instead, we drink at least 2 liters of water a day in all seasons of the year, not only in summer, even with the help of infusions and herbal teas. It is important for stimulate the kidneys and keep them active and functional to metabolism.
There are some situations in which it is not enough to act like this and it is necessary undergo dialysis, these are the most serious situations in which the diet fails to solve the problem and an external "intervention" is needed to purify the blood of excess chemicals, such as urea and creatine.
