Like many organs in our body, you almost never feel the kidney when it is normal; and when you do feel it, something must be wrong with it. The kidney has a very high potential, which means that it can replace the whole organ with a small part of its own work, and as long as a third of your kidneys are still working properly, you can maintain a normal body condition. Any lower than this level and toxins start to accumulate in the blood, and you get a feeling of fatigue and weakness; fluid cannot be excreted. This results in edema, shortness of breath and high blood pressure. At the later stage of kidney disease, which is the stage of kidney failure, the following symptoms may also occur. The kidneys are unable to remove waste products from the bloodstream, and these waste products accumulate in the body and make you feel unwell. The increase in urea will make you feel sleepy and nauseous. The actual fact that the kidneys can no longer promote the production of red blood cells in the body, you will feel fatigue, lack of energy and look pale. Because the kidneys cannot remove excess water from the body, fluid is retained in the interstices of the body’s tissues and you may find that your ankles and eyelids swell. If fluid builds up in your lungs, you may feel short of breath. ④Changes in urine volume Despite the weakened kidney function, urine can still be produced, however, unlike when it is normal, it does not contain the waste products it carries when it is normal, and the volume of urine does not fully indicate how well your kidneys are functioning. ⑤ Bad taste in the mouth Because the kidneys cannot remove waste products such as urea, these waste products will accumulate in the body, making your breath smell bad and you have no appetite. ⑥Urinary routine, ultrasound of both kidneys, kidney function test, combined with clinical symptoms can be the initial diagnosis.
