Urination Changes – the most common early symptoms of kidney damage:

• trouble urinating;
• urine’s color is pale, often need for urination and in large amounts;
• foamy urine;
• urine’s color is dark, reduced need for urinating or reduced amount or urine;
• often urges for urinating at night; pressure during urinating.

Swellings – If case of a kidneys’ function damaging, the body cannot release excess fluids and this leads bloating of the face, joints and limbs as well as to swellings.

Metallic Taste In The Mouth – because of the waste deposits in the blood, you can have a bad breath or a changed taste in the mouth. If the kidney is severely damaged you can experience big change in the taste of some foods or a low appetite.

Fatigue – if the kidneys are at a good health, they will produce EPO (erythropoietin), that is, a hormone that is responsible for producing red blood cells which supply the oxygen needed for the body. If the red blood cells are lowered, you start to experience fatigue, brain and muscles damage. This is also a common sign of severe anemia.

Pain – another very known sign of kidney damage or failure is an upper back pain, just where the kidneys are, and this pain can be as well accompanied by kidney infections or stones.
