Blood urea nitrogen is one of the main indicators of renal function. So the change of urea nitrogen have a big impact on the non-protein, normal urea nitrogen level: 2.86-7.14mmol / L, which is our definition of the reference value, once beyond this range, that is high urea nitrogen.

Blood urea nitrogen increased when renal insufficiency , but not the only clinical manifestations, there will be elevated serum creatinine, but also have increased blood pressure, loss of appetite, gum bleeding, electrolyte imbalance, metabolic acidosis, urine abnormal and other clinical manifestations, so BUN alone can not be said that renal insufficiency.

Three cases that may cause high urea nitrogen.

The first case: acute nephritis, chronic nephritis, toxic nephritis, severe pyelonephritis, renal tuberculosis, renal vascular sclerosis, congenital polycystic kidney and kidney tumors caused by renal dysfunction. Especially for the diagnosis of uremia have a special value, and its degree of increase is proportional to the severity of the disease, such as azotemia BUN more than 9mmol / L, to uremic BUN can be more than 20mmol / L, contribute to the disease estimates.

The second case: congestive heart failure, severe burns, shock, gastrointestinal bleeding, dehydration, severe infection, diabetic acidosis, adrenal insufficiency, liver and kidney syndrome.

The third case: high postrenalgia seen in urinary tract obstruction increased renal tissue pressure, so that glomerular filtration pressure decreased, such as prostatic hypertrophy, tumor compression caused by urethral obstruction or bilateral ureteral stones and so on. A simple increase in urea nitrogen can be due to excessive intake of protein in the diet caused by food, change the diet, balance the protein, sugar and food and vegetables with the mix, will soon be able to return to normal. Therefore, in order to clarify the cause, it is best to consult with the doctor after the decision of treatment.
