The symptoms of CKD

　　The symptoms of CKD
　　Changes in urine
　　The patients with CKD may experience some changes in urine.One is frequent urination,especially at night. This occurs when the concentrating ability of kidneys is impaired.Additionally, foamy urine and cola-colored urine can occur.Foamy urine is due to loss of extra proteins in urine. Cola-colored urine results from leakage of red blood cells in urine.
　　Puffiness or swelling
　　Puffiness or swelling can occur in legs and ankles and around the eyes. The diseased kidneys fail to filter out extra fluids from body. Another cause of puffiness is hypoproteinemia.
　　Fatigue and weakness
　　Fatigue and weakness in CKD is the result of anemia.Healthy kidneys can produce a hormone called EPO which can stimulate the bone marrow to make red blood cells.The diseased kidneys fail to perform the function, thus resulting in anemia.The patients with anemia may also experience pale face and shortness of breath.
　　Skin disorders
　　Skin disorders can occur as CKD progresses.Common skin problems include skin itching, dry skin, pale skin and urea frost. Skin itching is due to high building up of phosphorus in body. Dry skin occurs as the oil gland is impaired and restriction of fluid intake. Pale skin happens as a result of anemia. If high levels of urea nitrogen build up in skin, it will lead to urea frost.
　　Muscle weakness
　　Muscle weakness can be seen in CKD. It is attributed to multiple factors including decreased protein stores, anemia, chemical imbalance and heart problem.
　　Shortness of breath

　　Shortness of breath can occur if extra fluids build up in lung. In serious case, the patients even can not lie on back.Another cause of shortness of breath is inadequate supply of oxygen to body tissues and cells.
