Common Symptoms of Stage 3 Kidney Disease

Kidney Disease is a progressive disorder, in which kidneys do not lose their function at once but gradually. According to the glomerular filtration rate (GFR), kidney disease is divided into 5 stages. At stage 3 of Kidney Disease, GFR is 30 to 59 ml/min and some patients may not have outward symptoms, but others will.

1. Edema

In normal case, kidneys can discharge the excessive fluid out of body. However, in stage 3 of Kidney Disease, their kidneys are damaged moderately. As a result, the excess fluid stays in the body thus leading to edema. In the early period, the patients may only have edema in around eyes, face early in the morning and it will relieve in the afternoon. If left untreated, edema can cause painful swelling, high blood pressure and even heart failure.

2. Hypertension

Blood pressure refers to the force of blood against the blood vessels wall. In Stage 3 of Kidney Disease, there are mainly two reasons for hypertension. Healthy kidneys can secrete renin that plays an important role in maintaining blood pressure. When the kidneys fail to work normally, it can lead to renal ischemia and anoxia thus more renin will be secreted. As a result, the blood pressure will rise. Moreover, as the patients in stage 3 of Kidney Disease often have retention of water and sodium, it can cause their blood volume to increase. It is also an important cause of hypertension.

3. Anemia

In Stage 3 of Kidney Disease, as kidney function declines, they can not discharge the metabolic products from body as before, which can shorten the life expectancy of red blood cells greatly. In addition, the kidney is responsible for secreting erythropoietin that helps the bone marrow make red blood cells. However, for the patients with kidney disease, their kidneys can not work properly thus releasing less erythropoietin, resulting in fewer red blood cells.


In stage 3 of kidney disease, the kidneys have not yet been damaged seriously. Therefore, the patients should take the best therapeutic time to receive treatment as early as possible.
