Today, a small patient came to our department. Two weeks ago, her creatinine was about 220ummol/L, and now, it has reached 700ummol/L, which makes people sigh. When asked about the situation, it turned out that recently the patient had a so-called cold and her family did not communicate with us in time, and if she could have been seen in time, perhaps, her creatinine would not have grown so fast. Here, I would like to emphasize again to the patient that for patients with increased creatinine, every cold is likely to make the kidney function deteriorate rapidly, and some people will have heart damage such as panic, shortness of breath or even inability to lie down, in addition to kidney aggravation, so for such patients, once you have a cold, please contact your specialist as soon as possible. . Here again highlights an important issue, how can we do in the usual time to minimize the cold, then regular visits to the specialist to review the condition and guide the use of drugs, as well as the correct diet, appropriate exercise and effective psychological guidance has been an important means to avoid these troubles ah. In foreign countries, patients with chronic kidney disease rarely have sudden and rapid exacerbation of kidney function, which is also due to the regular monitoring, medication management and rehabilitation guidance on diet, exercise and psychological aspects under the lifelong guidance of a specialist. So, what should our patients do for your kidneys?
