Creatinine 200μmoI/L is still relatively serious, creatinine is the metabolic waste of the human body, mainly produced by muscle tissue metabolism, of which 99% of creatinine is excreted through the kidneys, so after the creatinine is elevated, it often represents a decrease in glomerular filtration rate and renal failure. There are many causes of creatinine elevation, but the most common ones in China are chronic glomerulonephritis, IgA nephropathy, hypertensive kidney damage, and diabetic nephropathy. The presence of elevated creatinine indicates that our kidney function is seriously damaged, so we should actively identify the cause, control blood sugar, blood pressure and blood lipids, and give Bailing capsule to protect the kidneys and urinary toxicity particles to reduce creatinine. The choice of antihypertensive drugs can be applied to the CCB class, such as amlodipine, nifedipine controlled-release tablets, etc. It is also necessary to control blood lipids and blood sugar, blood sugar control is based on insulin, elevated blood lipids can be treated with oral atorvastatin to lower lipids, through these comprehensive treatment to delay the failure of kidney function, when the creatinine exceeds 707μmoI/L, it is uremia, need to enter dialysis treatment.
