High urea and creatinine are likely to develop into uremia. Urea and creatinine are indicators of kidney function. When looking at kidney function, if these two are found to be elevated, it indicates renal failure, whether it is acute renal failure or chronic renal failure, it may develop into uremia. Although some acute renal failure may be cured after treatment, some patients who are not treated in time or are not very sensitive to treatment may also develop chronic renal failure and finally develop uremia. When the urea and creatinine are found to be elevated, while applying detoxifying drugs such as uremic pellets and Haikun Kidney Hi capsules, we must look for the underlying cause and treat it from the underlying cause, so that for patients with acute renal failure, there is a possibility of cure. For patients with chronic renal failure, it is possible to delay the deterioration of renal function and enter the stage of uremia as late as possible, which is very meaningful to improve the quality of life of patients.
