Common symptoms of kidney disease include changes in urination, swelling, fatigue, skin rashes and a metallic taste in the mouth, according to Life Options. Others include nausea and vomiting, a feeling of coldness, shortness of breath, dizziness, and pain in the legs and flanks.
Individuals suffering from kidney disease may need to urinate more frequently and in greater quantities, states Life Options. Paler urine usually accompanies this. Others may urinate much less frequently and in less quantity than normal, and in these cases, the urine's color is often darker. Foamy, frothy urine and blood-tinged urine also constitute changes in urine quality. Swelling occurs when the kidneys are no longer able to remove excess fluids from the body properly. The feet, ankles, legs, hands and face are common sites for kidney-related swelling. As the body retains excess fluid from kidney malfunction, waste material accumulates as well. This can cause skin rashes and itchy sensations.
Fatigue and subsequent anemia happen when the kidneys are unable to produce the hormone erythropoietin, says Life Options. This hormone signals the body to produce red blood cells, which carry oxygen. When the body absorbs less oxygen, the muscles and brain tire more quickly than normal. Dizziness and difficulty with cognitive tasks are a result of the brain not receiving enough oxygen, while shortness of breath occurs when the rest of the body is oxygen-starved.
