Uremia is the condition of having high levels of urea in the blood. Urea is one of the primary components of urine.It can be defined as an excess in the blood of amino acid and protein metabolism end products, such as urea and creatinine, which would normally be excreted in the urine.
BUN is an indication of kidney health. The normal range is 2.1–7.1 mmol/L or 6–20 mg/dL. [1]The main causes of an increase in BUN are: high-protein diet, decrease in glomerular filtration rate (GFR) (suggestive of kidney failure), decrease in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, [5] fever, rapid cell destruction from infections, athletic ...
Unless high blood levels of uric acid are determined in a clinical laboratory, hyperuricemia may not cause noticeable symptoms in most people. [5] Development of gout – which is a painful, short-term disorder – is the most common consequence of hyperuricemia, which causes deposition of uric acid crystals usually in joints of the extremities, but may also induce formation of kidney stones ...
The cause of DDS is currently not well understood. There are two theories to explain it; the first theory postulates that urea transport from the brain cells is slowed in chronic kidney disease, leading to a large urea concentration gradient , which results in reverse osmosis .
It may initially cause no symptoms. [28] In later stages, it can lead to difficulty urinating, blood in the urine or pain in the pelvis, back, or when urinating. [31] A disease known as benign prostatic hyperplasia may produce similar symptoms. [28] Other late symptoms may include feeling tired due to low levels of red blood cells. [28]
In medicine, the urea-to-creatinine ratio (UCR [1]), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea (mmol/L) and creatinine (Cr) (μmol/L). BUN only reflects the nitrogen content of urea (MW 28) and urea measurement reflects the whole of the molecule (MW 60), urea is just over twice BUN (60/28 ...
Glycine toxicity causes hyperammonemia, which manifests as CNS symptoms and nausea. Transient blindness can also occur. [12] Congenital hyperammonemia is usually due to genetic defects in one of the enzymes of the urea cycle, such as ornithine transcarbamylase deficiency, which leads to lower production of urea from ammonia.

Creatinine over 1.2 mg/dl or blood urea nitrogen over 20 mg/dl; White-blood-cell count under 4 × 10^9/L or over 30 × 10^9/L; Neutrophil count under 1 x 10^9/L; X-ray findings indicating hospitalization include: Involvement of more than one lobe of the lung; Presence of a cavity; Pleural effusion
