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 ...
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.
This is because urea is readily reabsorbed by the kidneys while creatinine is not. In congestive heart failure (a cause of pre-renal azotemia) or any other condition that causes poor perfusion of kidneys, the sluggish flow of glomerular filtrate results in excessive absorption of urea and elevation of its value in blood. Creatinine, however, is ...
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.

Citrullinemia is an autosomal recessive urea cycle disorder that causes ammonia and other toxic substances to accumulate in the blood. [1] Two forms of citrullinemia have been described, both having different signs and symptoms, and are caused by mutations in different genes. Citrullinemia belongs to a class of genetic diseases called urea ...
Protein toxicity is the effect of the buildup of protein metabolic waste compounds, like urea, uric acid, ammonia, and creatinine.Protein toxicity has many causes, including urea cycle disorders, genetic mutations, excessive protein intake, and insufficient kidney function, such as chronic kidney disease and acute kidney injury.
As one of the urea cycle disorders, citrullinemia type I needs to be distinguished from the others: carbamoyl phosphate synthetase deficiency, argininosuccinic acid lyase deficiency, ornithine transcarbamylase deficiency, arginase deficiency, and N-Acetylglutamate synthase deficiency. Other diseases that may appear similar to CTLN1 include the ...
The most common cause of polyuria in both adults and children is uncontrolled diabetes mellitus, [6] which causes osmotic diuresis; when glucose levels are so high that glucose is excreted in the urine. Water follows the glucose concentration passively, leading to abnormally high urine output. [citation needed]
