What Are the Symptoms of Stage 3 Chronic Kidney Disease (CKD)

In Chronic Kidney Disease (CKD), the patients lose their renal function in a gradual way. According to glomerular filtration rate (GFR), Chronic Kidney Disease (CKD) is divided into 5 stages. As different stages have varying-degree kidney damages, the patients present different symptoms in different stages.
In stage 3 Chronic Kidney Disease (CKD), the GFR decreases to 30~59 ml/min. At this stage, the patients have moderate renal damage and show the following symptoms.

1. Fatigue

The patients with stage 3 CKD often have fatigue and pale face due to anemia. Anemia in kidney disease is mainly caused in two ways. On one hand, the patients have poor appetite, nausea, vomit, and so on so the raw materials of blood are insufficient. Moreover, the impaired kidneys can not produce enough hemopoietin, it can cause the numbers of red blood cells to decline in blood.

2. Swelling

In healthy conditions, the kidneys are responsible for discharging fluid from blood. However, once the kidneys are impaired, they will lose that normal function. As a result, the fluid will permeate into tissues space leading to swelling.

3. Abnormal urination

Some patients with stage 3 Chronic Kidney Disease (CKD) can find foams in their toilet when urinating. This case may be related to the protein loss in the urine. Also sometimes the urine becomes red dark or tea-colored if it contains red blood cells in it.

4. Back pain

Back pain is a rare symptom for the patients with stage 3 CKD. However, in some particular diseases like Renal Cyst, Polycystic Kidney Disease (PKD), and Kidney Stones and so on, they will have back pain.

5. Skin itch


As the kidneys fail their function in filtering blood, a lot of uremic toxins will build up in blood. It can influence multiple organs and even skin. Therefore, the patients will have skin itch. Generally, dialysis can relieve this symptom.
