azotaemia
Noun: A medical condition characterized by an abnormally high level of nitrogenous waste compounds, such as urea, in the bloodstream. This accumulation occurs because the kidneys are not effectively filtering and excreting these waste products into the urine.
Azotaemia is a technical term used primarily in medical and clinical contexts to describe a state of impaired kidney function or renal insufficiency. It indicates a biochemical abnormality that is often a sign of an underlying disease.
- The veterinarian diagnosed the dog with azotaemia after reviewing the blood test results showing elevated urea and creatinine levels.
- Acute kidney injury can lead to severe azotaemia, requiring immediate medical intervention.
- Monitoring for azotaemia is crucial in patients with chronic renal disease.
- Pre-renal azotaemia: This specific type is caused by reduced blood flow to the kidneys (e.g., from dehydration or heart failure), not by direct kidney damage. The kidneys themselves may be structurally normal but underperforming due to the lack of adequate perfusion.
- Post-renal azotaemia: This type results from an obstruction in the urinary tract (e.g., a kidney stone or enlarged prostate) that prevents the normal flow and excretion of urine, leading to a backup of waste products.
- Azotemia: An alternative spelling of . The difference (using 'e' vs. 'ae') is a matter of regional spelling preference; both refer to the same condition.
- Uraemia (or Uremia): A more severe clinical syndrome that includes along with a wider range of symptoms and complications affecting the entire body, such as nausea, fatigue, and neurological changes.
- Nitrogen retention: A descriptive phrase for the process underlying azotaemia.
- Uraemia (Note: While closely related and often used interchangeably in casual medical speech, typically implies a more advanced, symptomatic stage of kidney failure compared to the biochemical finding of ).
- Renal insufficiency (a broader term for reduced kidney function, of which azotaemia is a key indicator).
Azotaemia specifically denotes the laboratory finding of elevated blood urea nitrogen (BUN). It is a sign, not a disease itself. The term does not describe the symptoms a patient feels (like uraemia often does) but rather the measurable chemical imbalance in the blood.
