Urea nitrogen is high many da?o.En diet is also important to note.
Indicators urea nitrogen normal blood: 2.86-7 .14 mmol / L, which is our definition of normality, once outside this range, which are high urea nitrogen.
High renal insufficiency blood urea nitrogen, but are not the only clinical manifestations, elevated serum creatinine also occur, but there will be blood pressure, loss of appetite, bleeding gums, electrolyte imbalance, metabolic acidosis, urine abnormalities and other manifestations clinics, so that high concentrations of blood urea nitrogen alone can not say that this is kidney failure.
Reason for the high visibility of urea nitrogen in the following three cases
In the first case: highest seen in, chronic nephritis, toxic nephritis, severe pyelonephritis, renal tuberculosis, renal vascular sclerosis, congenital polycystic kidney disease and renal dysfunction renal tumors induced acute renal nephritis. For diagnosis of particular value uremia, that increased with the degree of severity, such as more than 9 BUN mmol / L, in BUN uremia azotemia exceed 20 mmol / L, to help estimate the disease.
The second case: highest seen before renal congestive heart failure, severe burns, shock, gastrointestinal hemorrhage, dehydration, severe infection, diabetic acidosis, adrenal insufficiency, liver and kidney syndrome.
The third case: the high seen after renal tract obstruction due to an increase in pressure of renal tissue, the glomerular filtration pressure is reduced, such as an enlarged prostate, urethral obstruction caused by compression or both tumor sides of ureteral calculi. Elevated blood urea nitrogen can, simply because excessive consumption of foods rich in dietary protein caused by changes in diet, protein balance, sugary foods and mix vegetables, which will soon be back to normal. Therefore, as a clear cause, it is best to consult a doctor before deciding on treatment too.
Urea nitrogen diet high
1. decompensated Ccr20-50ml / min renal failure. Protein must be controlled at 45-50g, the protein must be of high quality protein. Vegetable protein intake should be minimal, since many conditions, such as nonessential amino acids, rice, vegetable protein is the best way to try to eliminate the surface contained. To apply contain high quality protein such as lean meat, fish, eggs and other foods.
2. hot to guarantee the total calories in order to reduce the consumption of proteins in vivo library ingredients. Provision of daily calories should 30Kca / Kg, the main source of carbohydrates and fats. Poor diet program can give the patient medicine Erchen (Pinellia, Poria, orange peel, licorice) and add Guya, The Divine Comedy and other drugs of Consumer Guide.
