Once, I met an anxious lady in the outpatient clinic who took her hand and pointed to the insignificant crescent moon on her fingernails and asked me:
She told me that she saw an article on the web:
Saying that there was no crescent moon or that the crescent moon was too small was a sign of health problems, she was so scared that she hurriedly came to me for verification.
I smiled and comforted her and said, "
Today I want to reveal to you a common small phenomenon in daily life - the crescent moon on the nails.
I believe many people have wondered why some people have obvious crescents on their nails, while some people have almost no crescents?
What's the secret behind this?
First, we need to understand what is a crescent moon?
In fact, the crescent moon is a part of the growth of the nail, and the scientific name is "nail half moon";
It is the translucent area of newly grown nail cells that appears when exposed to light.
Because these nail cells are fresh and rich in keratin cells, they will appear brighter and whiter in the sun.
The crescent moon is actually the new cells at the base of our nails, which are relatively tender and white during the growth process, so they form a unique small white bend.
Some people have a crescent moon that looks particularly clear, while others are not;
This has something to do with each of our physique and living habits.
Most people can see this tiny crescent moon on their fingers, but it's just a different size.
Second, how is the crescent moon formed?
It is made from a place called methyl at the base of the nail.
So the crescent moon you see is actually the part of the nail that hasn't completely hardened.
Some people may think that the bigger the crescent, the better, but in fact, it is not directly related to health;
It just means that your metabolism is more active, especially for people who often do physical work, and the crescent moon may be more obvious.
Third, why is it that some people's crescents are obvious, while others' are not?
It's a bit of a elementary school question.
1. First of all, it has something to do with our thyroid
If the thyroid gland is vigorous, the nails will grow like rabbits, swish, and the crescent will bulge and even become larger.
On the other hand, as soon as the thyroid gland is lazy, the nails will grow slowly, the crescent will retract, and if it is serious, it will be gone.
2. It is related to growth hormone
Also, the appearance of nails is different, some are white, some are transparent;
This is because the keratinocytes are aging, and this thing is quite obvious when you are young;
As I get older, my cells don't like to move, and the crescent moon slowly fades out.
3. Normal physiological phenomena
Young people look at the crescent moon obviously, and the elderly may not be able to see it very clearly, which is also normal, don't panic.
But don't underestimate this little crescent, it's a barometer, and it may know what is going on in the body.
All of a sudden, it changes, so you have to pay attention to whether there is something wrong with your body.
In short, the size of the crescent moon varies from person to person, the key is not to let it change suddenly, and the most important thing is to stay healthy.
Fourth, the more and bigger crescents on the nails, the healthier the body?
Each of our fingers basically has such a small white bend, but sometimes it is hidden in the flesh and cannot be seen.
Some people think that this thing can tell whether the body is good or not, but in fact, it is mostly born and has nothing to do with health.
But then again, if one day you notice that the crescent moon suddenly gets bigger and smaller, or flickers like a game of hide and seek, you have to be careful;
It's best to go to the hospital for a check-up, and don't rely on this self-diagnosis alone.
After all, if there is any illness, you have to listen to a professional doctor.
If nothing else, maintaining a healthy lifestyle is the king, so don't worry too much about the crescent moon.
Fifth, there are 4 changes in the nails, which need to be vigilant
The first is that the nails become thinner and break easily
This is not as simple as a simple calcium deficiency, it may be that the nutrition cannot keep up, and the iron, calcium, vitamin C and D deficiencies may be caused.
There is also that kind of nail fungus, which is a fungus, which is very annoying.
Second, look at those little holes in your nails
It's like pricking a needle, which may be insufficient nutrition, anemia, or thyroid problems;
Or a more complex pathology. I used too many chemicals, or I had a skin disease, and my nails didn't feel good.
Thirdly, there is the change of color
Turning white nails may indicate that the liver is not good, or that the nutrition is poor, and turning yellow and purple may indicate heart and lung problems.
These are all signals to watch out for.
Finally, a few black lines pop up on the nails;
It's not a trendy decoration, it may be that the methylmelanocytes are active, and you have to go and see if it is a benign disease.
In short, if there are these changes in the nails, and they are not a matter of time, it is best to see a doctor.
As a doctor, I would like to remind everyone not to be overly superstitious about health information on the Internet, and it is best to consult a professional doctor in person if you have any problems.
After all, everyone's physical condition is unique, and the correct health concept and scientific living habits are the real way to maintain health.
I hope this article can uncover the "mystery of the crescent moon" for everyone, and let's be a health expert together.
