Request the measurement of azotemia and common practice among doctors. This is an easily identifiable value through blood sampling. What is azotemia
Azotemia is nothing more than the value referred to the quantity of nitrogen (chemical symbol N) in the blood. It is considered an indispensable marker for evaluating the functionality of the kidneys. An alteration in blood urea nitrogen could indicate a defect in purification of these organs.

  • Did you know
    There are two types of nitrogen in the blood: protein and non-protein. The first type is the one that our body exploits at the level of amino acids – and therefore of proteins – the second is instead the one that is part of the waste substances and that is present in urea. Among the nitrogen compounds we also remember creatinine and ammonia.

What Blood
Tests Detect Different types of blood tests detect the various nitrogen compounds found in our bodies. In the medical report you will find them with the name of Azotemia, Urea Nitrogen and creatinine.

  • Normal values ​​of BUN (
    Urea Nitrogen): 1021 mg /

High BUN and Symptoms
High BUN can cause several symptoms. Among these the most important are fatigue and weakness, skin paleness, weight loss, tachycardia, vomiting, hypertension and tremors. Symptoms that need to be investigated
There are some symptoms that need to be investigated and the doctor may require an assessment of azotemia, creatinine and urea nitrogen. These include:

  • Dark urine
  • Foamy urine
  • Continuous thirst and frequent urge to urinate
  • Bone and joint pains (cramps)
  • Restless Legs Syndrome
  • Changes in appetite
  • Itching
  • Exhaustion
  • Sleep disorders
  • Swelling in the hands and feet

High blood azotemia: the causes
In general, elevated blood azotemia levels are attributable to a kidney disorder related to purification problems, however there can be many other triggering causes:

  • Diabetes
  • Dehydration
  • Excessive sweating
  • High-protein diet
  • Cirrhosis of the liver
  • Gastrointestinal bleeding
  • Uses of drugs (diuretics, cortisones)
  • Glomerulonefrite
  • Gotta
  • Hyperthyroidism
  • Hypertension
  • Epilepsy
  • Hypokalaemia
  • Hemolysis
  • Heart failure
  • myeloma
  • Neoplasms (especially kidney)
  • Infectious diseases
  • Bladder obstruction
  • Leukosis
  • Conn syndrome
  • Shock
  • Tuberculosis (renal)
  • Calculated
  • Enlarged prostate

Because the diet can influence the feeding in the high azotemia
Our diet, especially if it is too protein, can raise the Nitrogen values ​​in the blood. Proteins, in fact, contain about 15% of Nitrogen. Once the amino acids are metabolized, the nitrogen should be sent to the urea and excreted in the urine. But if the protein intake is too abundant and the kidneys do not work properly, a part of nitrogen may not be completely eliminated. Dietary Tips for High Azotemia
Patients with high blood urea nitrogen should minimize high-protein foods such as legumes, eggs, cheeses, meat and fish. On the other hand, it would be desirable to increase the consumption of artichokes, green leafy vegetables and beets. All accompanied by good hydration with increased water between meals. High azotemia: it is always pathological
As often happens, not all alterations are pathological, especially when it comes to small changes. For example, in advanced age, slight increases are considered normal, the same in pregnancy and in pediatric subjects.
