What Are Common Symptoms Of Chronic Kidney Disease

Many people who experience chronic kidney disease (CKD) do not have symptoms at first. This is known as the silent phase of the disease. Signs and symptoms of CKD develop over time if kidney damage progresses slowly. Well, what are common symptoms of CKD?

Signs and symptoms of CKD may include:

1. abnormal urine amount

Most CKD patients will experience abnormal urine amount which can refer to frequent urination at night, reduced urine and even no urine. In normal condition, a person’s urine is 1000ml to 2000ml per day. If the urine is more than 2500ml, it is called diuresis. If it is less than 400ml, we call it oliuria and if it is less than 100ml, we call it anuria.

2. protein in urine

Proteinuria is a typical symptom of CKD which is caused by the damage of renal glomerular filtration membrane.

3. hematuria

Hematuria includes gross hematuria and microscopic hematuria. In gross hematuria, the urine color becomes cola-colored or tea-colored. In microscopic hematuria, the number of red blood cells is at least 3 per high power field under microscopy.

4. high blood pressure

High blood pressure is the late symptom, which is caused by long time of CKD. When patients are suffering from kidney disease, the renal glomerular filtration rate decreases, but the reabsorption ability of renal tubules’ function keeps normal. So the imbalance of renal glomerulus and renal tubules take place, which leads to retention of water and sodium, thus causing high blood pressure.

5. edema

The swelling first appears around eyelids. However, in severe case, patients may suffer from systemic swelling.

6. anemia

First, the generation of red blood cells decreases. Because kidney function is damaged, the EPO in kidney disease will be produced less, thus leading to anemia.

Second, in the late stage of kidney disease, a lot of toxic substances accumulate in the body, which causes the damage to the red blood cells and hematopoietic function. Short lifespan of red blood cells triggers anemia.

Signs and symptoms of kidney disease are often nonspecific, meaning they can also be caused by other illnesses. This is because your kidneys are highly adaptable and able to compensate for lost function, signs and symptoms may not appear until irreversible damage has damaged. We cannot list all kidney symptoms here. If you feel any discomfort, see a doctor immediately so as not to miss the best treatment time.
