Chronic renal failure can be present for many years before you notice any symptoms.These are:

increased urination, especially at night foamy or bubbly urine (indicates proteins are present in the urine) urine that is cloudy or tea-coloured Other symptoms aren't as obvious, but are a direct result of the kidneys' inability to eliminate waste and excess fluid from the body:

puffy eyes, hands, and feet (called edema) high blood pressure fatigue shortness of breath loss of appetite nausea and vomiting (this is a common symptom) thirst bad taste in the mouth or bad breath weight loss generalized, persistent itchy skin muscle twitching or cramping a yellowish-brown tint to the skin As the kidney failure gets worse and the toxins continue to build up in the body, seizures and mental confusion can resultIf your doctor suspects that you may be likely to develop renal failure, they will probably catch it early by conducting regular blood and urine tests.If regular monitoring isn't done, the symptoms may not be detected until the kidneys have already been damaged.When you first start losing kidney function, the healthy tissues in the kidney will help to compensate for the loss by working harder.

Chronic renal failure can be present for many years before you notice any symptoms. When you first start losing kidney function, the healthy tissues in the kidney will help to compensate for the loss by working harder. If your doctor suspects that you may be likely to develop renal failure, they will probably catch it early by conducting regular blood and urine tests. If regular monitoring isn't done, the symptoms may not be detected until the kidneys have already been damaged. Some of the symptoms – such as fatigue – may have been present for some time, but can come on so gradually that they aren't noticed or attributed to kidney failure.

Some signs of chronic renal failure are more obvious than others. These are:

increased urination, especially at night
foamy or bubbly urine (indicates proteins are present in the urine)
urine that is cloudy or tea-coloured
Other symptoms aren't as obvious, but are a direct result of the kidneys' inability to eliminate waste and excess fluid from the body:

puffy eyes, hands, and feet (called edema)
high blood pressure
fatigue
shortness of breath
loss of appetite
nausea and vomiting (this is a common symptom)
thirst
bad taste in the mouth or bad breath
weight loss
generalized, persistent itchy skin
muscle twitching or cramping
a yellowish-brown tint to the skin
As the kidney failure gets worse and the toxins continue to build up in the body, seizures and mental confusion can result
