Treatment for stage 3 chronic kidney disease, or CKD, involves eating a healthy diet and taking medicine to control glucose levels and high blood pressure, according to DaVita. Many CKD patients also have diabetes and high blood pressure, and treating these conditions helps prolong kidney function. Studies show that blood pressure medicine helps slow kidney damage in patients with diabetes even when they do not have high blood pressure.
A healthy diet for stage 3 CKD includes eating foods with high-quality protein and potassium, decreasing saturated fats, limiting calcium and phosphorus consumption, and eating some grains, fruits and vegetables as long as potassium and phosphorus levels are normal, advises DaVita. Patients who also have diabetes should cut down on carbohydrates, and patients with high blood pressure should limit their sodium intake. Exercising regularly and avoiding cigarettes also help prolong kidney health.
Patients with stage 3 CKD have moderate damage to their kidneys, explains DaVita. At this stage, patients become more likely to develop complications from kidney disease, such as high blood pressure, anemia and early bone disease. Common symptoms at this stage include fatigue, fluid retention or swelling of the extremities, increasing urinary frequency or changes in urine color, sleep problems due to muscle cramping, and kidney pain.
