uremia(u-re'me-a) [ uro- + -emia]
Although nitrogen-containing waste products have long been considered the principal cause of uremia, other metabolic waste products (such as glycosylated wastes and byproducts of abnormal oxidation) may actually be the most important toxins responsible for uremia.
Symptoms include nausea, vomiting, anorexia, headache, dizziness, coma, or convulsions.
Dialysis removes many soluble waste products that accumulate in renal failure and helps improve some conditions associated with uremia. Other uremic conditions can be alleviated with a protein-restricted diet, careful management of acid-base balance, and calcium and folate supplementation.
