Hi,
The symptoms of kidney failure develop slowly over time. These signs may include
* Decreased urine output or no urine output
* Nausea
* Vomiting
* Loss of appetite
* Fatigue and weakness
* Sleep problems
* Decreased mental sharpness
* Muscle twitches and cramps
* Swelling of the feet and ankles
* Persistent itching
Signs and symptoms of kidney failure are often nonspecific, meaning they can also be attributed to other illnesses. In addition, because your kidneys are highly adaptable and able to compensate for lost function, signs and symptoms of kidney failure may not appear until irreversible damage has occurred.
