What are the symptoms of chronic kidney failure?

The very unfortunate thing about this disease is the fact that you may start to have symptoms only a few months after your kidneys begin to fail. Most people do not have symptoms during the initial stage of the disease. In fact, it has been reported that many patients do not have symptoms for as long as 20 to 30 years or more. Hence some doctors refer this to as the "silent" phase of the disease.

As your kidney function gets worse, you may:

1) urinate less frequently than normal.
2) have eodema i.e. swelling from fluid buildup in your tissues.
3) feel very tired or sleepy.
4) not feel hungry, or may lose weight without reason.
5) feel nauseating i.e. sick to your stomach or vomit.
6) have trouble in having a good night’s sleep.
7) Have headaches and difficulty in concentrating
