When meeting with friends who haven't seen each other for a few years, they are sometimes surprised to find that the traces left by the years in appearance and physique. Perhaps after the party, in addition to lamenting that the other party is a lot older, they will also take a good look at themselves. Have you become so old too?
The maturity and aging of appearance often reflects the actual age. Although we sigh, everyone can accept it: this is a natural process.
However, with the degradation and aging of organ functions, most people have no concept. The most amazing thing about the body is that the functions of many organs have to decline until the last moment before some uncomfortable symptoms will gradually appear. If you happen to be a person with a strong personality and a habit of patience, you may also find that a certain organ function has been damaged when you can't support it. It's too late.
This is true for almost all organs. I am a nephrologist. Let's start with the kidneys.
Let's look at the picture first：
Looking at the picture, it can be seen that the kidney function of newborn babies is still developing, so the filtration rate of renal filaments is only less than half that of adults. With development and growth, by the age of two, it is roughly close to the adult's renal filaments filtration rate.Generally normal and healthy people, from the age of 20-30, the filtration rate of renal filaments is like a slide. As they get older, the value will be lower. The average decline rate of normal people is about 1 (mL/min/1.73m2) a year. About.
You will definitely ask, everyone looks different, and the differences are so big. Will everyone's kidney silk ball filtration rate fall on that line so just right?
Good question!The figure above shows the average value.So if you include more data and look at it together, the data distribution of the overall population will be as shown in the figure below.：
The figure above is a distribution map made by counting the data of all people (including patients with chronic kidney disease) together. 95% of the population is distributed between two blue lines (high standard and low standard).，
Why do you want to write this article and draw these two pictures?
In addition to letting everyone know that kidney function will slowly decline with age, I also want to tell everyone that if you only look at the value of renal filamentous membrane filtration rate, you don't know if the kidneys are sick.For example, the filtration rate of renal silk globules is 60. If it is a 20-year-old young person, it may be very problematic, while an 80-year-old person is likely to be very healthy.Nowadays, the average life span of a person is about 80 years old, so it is also very common for health check-ups to report data below 90.
Finally, the organs of the body, just like our appearance, will slowly age. Although the speed is not fast, it still needs everyone's care and good care from time to time. One day, when we live to the age of 100, the kidneys will be able to continue to work well, and we will be able to maintain a healthy body for a long time. It is considered a good life~!
