Creatinine is a metabolic waste of human body, mainly produced by muscle tissue, its production and excretion is relatively constant, basically not affected by diet and other factors, so it is mainly used to respond to glomerular filtration rate, kidney function, when creatinine is elevated, often indicates the emergence of kidney damage, common causes are chronic glomerulonephritis, hypertensive kidney damage, IgA nephropathy, acute tubular necrosis, etc.. For treatment, we must first clarify the cause. If the creatinine is elevated due to acute kidney injury, then we should remove the cause and give symptomatic treatment, such as acute interstitial nephritis, and give small doses of hormone application, and the kidney function may return to normal, while if the creatinine is elevated due to urinary tract obstruction, restore the ureter and urethra, the creatinine will drop. If the creatinine is elevated due to chronic diseases, then you can protect your kidneys and lower creatinine by taking oral medications such as Bailing Capsule and Urotoxic Granules, and control blood sugar, blood pressure and blood lipids, as well as low salt, low fat and high quality low protein diet to slow down the deterioration of kidney function. When creatinine exceeds 707umol/L, it is uremic syndrome, then it is necessary to carry out renal replacement therapy, the common ways are hemodialysis and peritoneal dialysis, these two kinds of dialysis long-term prognosis is the same, each has its own advantages and disadvantages, you need to choose the dialysis method according to your own needs.
