Do you know the kidneys?
     
The kidney is an important organ in the human body, is located below the diaphragm, on both sides of the spine, such as beans, one on each side. Each kidney weighs 120~150 grams, 10~12 cm long, 5~6 cm wide, and 3 cm thick. The kidneys in women are usually smaller.

       The main role of the kidney: first, excretion of excess water in the body; two is to exclude toxins in the body; three is an important endocrine function, such as maintaining the stability of blood pressure, prevent anemia and bone disease. Once you suffer from kidney disease, the following conditions may occur, such as abnormal urine volume (polyuria or oliguria), abnormal urination (frequent urination, nocturia, etc.), hematuria, proteinuria, edema, hypertension, etc.. It is worth mentioning that the kidneys have a strong reserve capacity, and even if half of the function has been impaired, the patient can also have no symptoms. Therefore, we can not think that without symptoms, there will be no kidney disease, you can relax vigilance, which is extremely dangerous. If everyone in the health examination was suspected to have kidney disease, such as urine found hematuria, proteinuria, even without symptoms, it should go to the hospital for kidney, early diagnosis and early treatment.
