Comment: There are three major ways to protect kidney function, i.e. keep your mouth shut, keep your legs open, and regulate the use of medication. In other words, to cultivate a healthy lifestyle and rationalize the diet structure; to strengthen exercise and physical fitness; and to standardize and rationalize the use of medication when combined with other diseases. The first two are more talked about in the previous introduction, but today we recommend a practical model article on how to avoid drug-related kidney damage, which tells you how to avoid drug damage to the kidneys, regardless of whether Chinese or Western medicine may produce nephrotoxicity, and how to use drug therapy as a last resort.
