Hello, Director Sun: I am only 20 years old, but I have nephritis, and I was diagnosed with IgA nephropathy by kidney puncture. Because I don’t feel any discomfort, only the red blood cell + was found in the urine test, the doctor didn’t make special treatment, but my family is very anxious, they want me to take Chinese herbs for a long time, saying that Chinese herbs won’t hurt my kidneys, is it really true? Answer to the reader: Chinese herbal medicine has many desirable points in the treatment of chronic kidney disease, and also has certain effectiveness, so it is being commonly used and discovered. Although Chinese herbs have few side effects, they are not completely free of nephrotoxicity, which is still a problem that should be taken seriously, especially when used in large amounts and for long periods of time, the problem of nephrotoxicity has been reported repeatedly. For example, in recent years, there are weight loss herbs (Fang Yi, Hou Pu) cause chronic interstitial nephritis and chronic renal failure in serious cases; there are also examples of acute renal failure caused by Mouton, and the General Hospital of Nanjing Military Region published an article on “renal lesions caused by Chinese herbs” in 1994, all of which indicate that certain Chinese herbs can cause kidney disease, and certain Some of these herbs can induce chronic lesions in the interstitial tubules, for which there is no effective prevention and treatment method, and eventually enter into advanced renal failure. The medical community has called for strict indications in the treatment of kidney disease with herbal medicines, and close observation of the application process for side effects such as kidney damage to prevent adverse reactions. According to the survey, when herbal medicine produces kidney damage, there is an increase in urine protein, and even a large amount of proteinuria; the phenomenon of increased urine sugar accounts for half, the incidence of renal tubular acidosis 42%, chronic anemia up to 63%, the decrease in kidney function for 67%, a few people also appear hypertension. In conclusion, regular testing during the treatment process, such as weakness, anemia, increased urine protein, urine sugar, should pay attention to further examination of renal function and tubular damage laboratory items, early detection of problems, stop the use of drugs to prevent continued aggravation of kidney damage.
