symptoms of kidney failure

In the commencement, kidney failure may be asymptomatic (not producing any symptoms). As kidney function reduces, the symptoms are related to the inability to regulate water and electrolyte balances, to clear waste products from the body, and to promote red blood cell production. Lethargy, weakness, shortness of breath, and generalized swelling could happen. Unrecognized or untreated, life-threatening situation can develop.

Metabolic acidosis, or increased acidity of the body due to the inability to produce bicarbonate, will alter enzyme and oxygen metabolism, causing organ failure.Lack of ability to excrete potassium and rising potassium levels in the serum (hyperkalemia) is associated with fatal heart rhythm disturbances (arrhythmias).

Increasing urea levels in the blood (uremia) can affect the function of a variety of organs ranging from the brain (encephalopathy) with alteration of thinking, to inflammation of the heart lining (pericarditis), to decreased muscle function because of low calcium levels (hypocalcemia).
