Study Notes
Blood Urea Nitrogen (BUN) Overview
- Urea is formed in the liver as the final product of protein metabolism.
- Digestion of proteins breaks them down into amino acids.
Metabolism of Amino Acids
- Amino acids undergo catabolism in the liver, resulting in the production of ammonia.
Renal Failure Conditions
- Uremia is a syndrome indicating renal failure with elevated BUN and creatinine levels, accompanied by clinical symptoms.
- Azotemia refers to a rise in serum BUN and creatinine levels, occurring without clear signs of renal failure.
- End Stage Renal Disease (ESRD) is diagnosed when only 10% of renal function remains.
Acute Kidney Issues
- Acute Renal Failure (ARF) is characterized by a sudden decline in kidney function, marked by increased BUN and creatinine levels.
- In cases of ARF, the urine output is significantly altered, reflecting the abrupt kidney dysfunction.
