By stage 3, there is a moderate decline in kidney function. In this stage, the buildup of waste products may start to appear within the blood, and symptoms could therefore affect day-to-day living. A number of people start to feel tired, have swelling in their hands or feet, muscle cramps, and changes in the frequency of urination.
It is during this stage that medical management becomes very important. Physicians may prescribe dietary changes to lighten the load on the kidneys, including low-protein, low-phosphorus, and low-potassium diets. Medications that control blood pressure, treat anemia, and protect the health of the bones are common. The intent of this stage is to slow further damage and prevent complications.
