When the kidney deteriorates, toxins in the blood build up causing the person to feel weak. Anemia, a condition wherein there is not enough hemoglobin, the protein in red blood cells that carries oxygen. Blood loss or decrease in RBC production can cause anemia, which are common in patients who have kidney impairment and failure.
When urea and other toxins are not properly excreted by the kidneys, it accumulates in the body. Uremic encephalopathy is a disorder that occurs when too much urea reaches the brain, resulting in confusion, drowsiness, inability to concentrate, and even coma.
