What does uremia indicate in chronic kidney disease?

Improved kidney function

Accumulation of waste products in the blood

Uremia is a clinical condition that arises as a result of the accumulation of waste products in the bloodstream due to impaired kidney function, particularly in chronic kidney disease (CKD). In CKD, the kidneys gradually lose their ability to filter various waste materials, such as urea and creatinine, effectively. As these waste products build up in the blood, they can lead to a variety of adverse health effects, including symptoms like fatigue, nausea, confusion, and itchiness.

The presence of uremia signifies that the kidneys are no longer able to maintain the necessary balance of electrolytes and waste products, indicating a significant stage of kidney dysfunction that may necessitate intervention, such as dialysis or kidney transplantation, to manage these accumulated toxins.
