1. Discolored urine

The kidneys are responsible for producing urine and removing waste from the body, so if it has unusual signs in color, smell, and frequency, you must be careful because you may have kidney failure. For example, frequent urination, urination at night, blood in the urine, foamy urine, green/red discoloration...

2. Difficulty sleeping, sleep apnea

People with kidney failure often have difficulty sleeping, tossing and turning, waking up in the middle of the night. In addition, when sleeping, they often stop breathing for a few seconds to 1 minute, then breathing returns to normal. In addition, loud snoring also warns of kidney health problems. Buy vitamins and functional foods

3. High blood pressure

In the body, the kidneys and the circulatory system depend on each other. The kidneys contain small nephrons that filter waste and fluid from the blood, so kidney problems will cause high blood pressure.

4. Back pain

Kidney failure can lead to back pain, especially in the lower ribs or groin area. If back pain is accompanied by fatigue, vomiting, frequent urination, high body temperature, then go to the doctor soon because it can be a warning sign of kidney failure from the body.

5. Swollen ankles

Kidney failure will lead to sodium retention, causing swelling of the ankles, hands and feet.

6. Shortness of breath

Frequently feeling short of breath, especially when moving or carrying heavy objects, is due to kidney failure. When the kidneys are not strong enough to perform their detoxification function, the body will feel uncomfortable and always feel short of breath.

7. Bad breath

One of the common signs of kidney failure is bad breath. Bad breath is caused by too many toxins and infections in the body because the kidneys have severely impaired function and cannot eliminate toxins.

8. Itchy skin

Healthy kidneys will help remove waste and excess fluid from the blood, helping red blood cells to be healthy and the skin to be rosy and smooth. On the contrary, unhealthy kidneys will cause itchy skin, dry skin, and peeling skin.
