Creatinine 1100umol/L indicates that the kidney function has been severely diminished and has entered the uremic phase, which requires renal replacement therapy, such as hemodialysis or peritoneal dialysis. If these treatments are not carried out, there is a risk of nausea, vomiting, poor nausea, and in serious cases, a series of complications such as severe edema, chest tightness, and difficulty in breathing, etc. Moreover, the long-term increase of toxin accumulation in the body is damaging to various organs such as the heart and lungs, which can cause uremic pneumonia and uremic encephalopathy, so it is still necessary to carry out renal replacement therapy regularly. At present, with the level of dialysis and the current status of dialysis in China, even if uremic patients start hemodialysis treatment, they still have a survival period of about 15 years, during which they should also take regular oral medications, such as iron, calcium tablets and osteoporosis, to prevent the occurrence of renal anemia and renal bone disease, so as to improve the quality of life.
