There may be no signs of Chronic Kidney Disease in the beginning. This is because the damage to your kidneys is still mild. The only way to identify kidney disease at an early stage is through testing, including urine and blood tests. Symptoms of Chronic Kidney Disease include nausea, weakness, fatigue, trouble in sleeping, swelling in the feet and ankles and changes in urine habits. However, most people don’t notice symptoms until the kidney damage is severe.
