What are the symptoms of kidney failure?

Poor kidney function is quite harmful to human health and can easily cause a variety of symptoms, such as frequent feelings of lack of strength and fatigue, loss of appetite, and even nausea and vomiting. It often causes proteinuria, excessive foam during urination, low back pain, decreased sexual function, etc.

1. Boring.

When the kidney function is poor, many wastes are difficult to excrete from the urine, resulting in feelings of lack of energy, fatigue, weakness, and other signs of lethargy. If the kidneys are diseased, nutrients such as protein will leak out of the kidneys and be excreted from the body through urine, which may also cause weakness. Some patients ignore kidney problems, thinking they are due to overwork or other reasons.

2. Don’t want to eat.

Loss of appetite, anorexia, or even nausea and vomiting are also common symptoms of kidney disease. Some patients always go to the gastroenterology or hepatology department first to see if they have stomach or liver disease. But when they find out they don’t have stomach or liver disease, they just leave it alone and forget to see a nephrologist, which delays their treatment.

3. The urine is foamy.

There are many reasons why there is foam in the urine. If protein leaks from the kidneys into the urine, the urine will be foamy.

4. Low back pain.

The kidneys are located on both sides of the spine in the waist, so when the kidneys are diseased, you will feel back pain.

5. Urinating more or less frequently. A healthy person urinates about 4-6 times a day, with a urine volume of about 800-2000 ml. If the frequency of urination and urine volume are too much or too little, you should pay attention.

6. Edema.

Drinking too much water, sleeping too long, being too obese, etc. may cause slight edema or transient edema in the eyelids, face, calves, etc. If this is not the case, you should suspect that there is a problem with your kidneys.

7. Urine protein and occult blood.

The presence of protein or occult blood in the urine is an important indicator of kidney disease, which can be confirmed by a routine urine test. But sometimes doctors who are not specialized in nephrology may overlook this point. It is recommended that you consult a nephrology specialist.

8. Anemia.

Patients with anemia often go to the hematology department to see a doctor for anemia. In fact, in addition to excreting waste and other functions, the kidneys also have endocrine functions and secrete hematopoietic hormones. When kidney function is impaired, anemia can also occur.
