”Every 10 people in a person may suffer from kidney disease”, so many people “talk about kidney”. As long as the adverse reactions to drugs with kidney damage will not dare to eat! In fact, many kidney diseases can be prevented, the Chinese Medical Association of nephrology branch of the main committee of Professor Yu Xueqing interviewed by the Yangcheng Evening News, to teach you how to pay attention to the details of life, to reduce the occurrence of kidney damage. Details a food choice do not single Professor Yu Xueqing introduced, excessive intake of heavy metals will cause damage to the kidneys, especially the renal tubules, which has been confirmed by scientific research. But the relationship between heavy metal intake and the degree of kidney damage has not been studied. He said that the First Hospital of Sun Yat-sen University intends to lead a multidisciplinary study on this topic in areas with serious heavy metal pollution, which is very meaningful for the prevention of heavy metal-related kidney damage, and also helps to promote the introduction of government intervention measures. As a general reader, what can we do to reduce the intake of heavy metals? Professor Yu Xueqing suggests that buying organic or pollution-free food is one way to stay away from heavy metal pollution, and that eating as diverse a diet as possible is also an effective measure. He explained that different vegetables are grown in different areas, and their absorption and residues of pollutants are different, so it is not easy to accumulate heavy metals in our bodies by eating them in different ways. The second detail is to drink more water. The problem of excessive heavy metals may also exist in the drinking water. Professor Yu Xueqing said that if you are not sure about the water source, you can install a filter at home, which is also conducive to the filtering of heavy metals. In addition, you should also pay attention to drink more water. Professor Yu Xueqing believes that the kidney is the body’s “purification center”, its main function is to remove the body’s metabolic products and toxins, regulate the body’s water-salt and acid-base balance, to maintain the stability of the body’s internal environment. Harmful substances are eventually metabolized out of the body through the kidneys, and if they cause damage to the kidneys, they need a certain amount, especially some harmful substances deposited in the kidneys, drink more water and urinate more, which is conducive to the discharge of these harmful substances; even for other types of harmful substances, drinking a lot of water can also play a diluting role, the concentration of harmful substances is low and the natural damage to the kidneys will be reduced. Details three cold medicine do not eat at will Many people do not feel well with the cold, they go to buy their own medicine to eat, eat not good to buy a try, which will also increase the risk of kidney damage. Why is a small cold medicine so powerful? Professor Yu Xueqing explained, “medicine is three points of poison”, the kidneys are very sensitive to drugs. People take medicine, the drug through the blood circulation to the whole body, and eventually most of the kidneys to excrete to the body. We are more familiar with the daily cold medicine contains antipyretic and analgesic ingredients, with varying degrees of nephrotoxicity, if taken in excess may lead to acute kidney damage, clinical often encountered due to the abuse of cold medicine caused by acute kidney injury and even kidney failure cases. Professor Yu Xueqing reminded readers that they must be very careful when using medicines for colds, not to buy medicines from pharmacies casually, or think that cold medicines are over-the-counter medicines can be eaten casually, or to get better quickly, several cold medicines together. Especially two or more cold medicine with similar ingredients taken at the same time, it is equivalent to increase the dose of drugs, the risk of adverse reactions will increase exponentially. But this does not mean that cold medicine can not be eaten, it becomes a choking food. The same reasoning applies to other drugs that may have nephrotoxicity. If the drug can do allergy testing (such as skin testing), it is best to do before eating, because if the body has an allergic reaction to the drug, the risk of kidney damage will be significantly higher. Details four Chinese medicine do not eat long-term Professor Yu Xueqing is the first epidemiological survey of chronic kidney disease in Guangdong Province in 2007, it is this survey to get “one in ten adults suffer from chronic kidney disease” found. In the survey, they found that kidney damage caused by drug toxicity accounted for 3.6% of chronic kidney disease, which indicates that drug-related kidney damage caused by drug abuse or irregular drug use is also a cause of kidney disease increasing year by year, which should not be taken lightly. He introduced, especially in Guangdong people have the habit of taking Chinese medicine, the nephrotoxicity of Chinese medicine should be paid special attention. At present, it has been clarified that the ingredients of Chinese medicine that may bring about kidney damage are mucuna pruriens, antibiotics and aristolochic acid, etc. The drugs containing these ingredients include Bazheng Pill, Dahuang Qingzhi Pill, Guoxi Pill, Gynecological Fenqing Pill, Xinyi Pill, Pure Yang Zhengqi Pill, Danggui Sihui Pill, Doutai Pill, Guanxin Suhe Pill and Xixiang Haisheng Pill. He warned that patients with kidney or gastrointestinal problems should be especially careful when taking these drugs, not to take too large a dose and not to take them for too long. Some chronic patients may need to take Chinese medicine for a long time, sometimes for months or even years, and even if the drugs do not contain mucuna pruriens, antibiotics and aristolochic acid, they need to be closely monitored for kidney function and kidney damage, in case they contain unknown ingredients with kidney-damaging effects. Folk remedies should not be easily trusted, for example, the so-called “stone removal soup” has a strong nephrotoxicity. Details five annual check kidney function, urinary routine Because the kidneys have a strong compensatory, many patients with a large percentage of kidney damage, but still may not have any symptoms, and then go to the doctor with symptoms, may have developed to uremia. Professor Yu Xueqing suggests that whether it is personal physical examination or unit physical examination, it is best to add urinary routine examination to the examination of kidney function and kidney ultrasound. Now many units physical examination will check blood creatinine (kidney function), although this index is important and can reflect the functional status of the kidneys, but can not accurately reflect the kidney damage. The kidney has a strong reserve and compensatory capacity, when 40% of the 100,000 kidney units are damaged, the remaining kidney units may still work as usual and the blood creatinine is still in the normal range. Only when more than 50% of the kidney units are damaged and the remaining kidney units are not working enough to eliminate toxins from the body, does the blood creatinine show abnormalities. Urine routine can make up for this deficiency. Urine routine can check for hematuria and urine protein, which can indicate kidney damage in a more timely and early stage. Moreover, routine urine tests are inexpensive and completely non-invasive.
