Definition
The term hyperazotemia indicates an increase in the concentration of non-protein nitrogen in the blood; this substance represents a waste product of protein metabolism, with normal values in the blood ranging from 10 to 50 mg / dl
Hyperazotemia is usually found:
- in the conditions in which kidney function is reduced, as in the case of acute or chronic renal diseases (eg glomerulonephritis, polycystic kidney disease, pyelonephritis, etc.)
- in the presence of obstacles to urinary outflow (eg calculations or enlarged prostate)
- in case of reduced blood flow to the kidneys (eg trauma, burns or bleeding).
Hyperazotemia also recognizes extrarenal causes. In particular, it can be a sign of severe dehydration, shock, biliary tract infections and heart failure.
Other conditions that can increase azotemia are liver cirrhosis, gout, gastrointestinal bleeding and some infectious diseases (eg leptospirosis and renal tuberculosis).
A high blood urea nitrogen level is also evident in those who adopt a high-protein diet, especially if the water supply is reduced. Hyperazotemia can also be linked to pregnancy, fasting, excessive physical activity or taking drugs with toxic action on the liver.
