What Is Acute Renal Failure?
5. Signs and Symptoms
Some people with acute renal failure do not demonstrate any symptoms, but this is not usual. One of the first signs of the condition is a reduction in urine elimination, though this symptom is not always present. People with the condition often have swelling in their ankles, feet or legs due to fluid retention.
Cardiovascular signs such as shortness of breath, chest pain and irregular heartbeat are sometimes present. There is also the potential for nausea, confusion, weakness and fatigue. Rarely, and in more severe cases, an individual may experience seizures or slip into a coma.
