Aunt Zhao thought that she had not felt any discomfort recently. Why was there something wrong with her body? She hurriedly asked her neighbor why. The neighbor replied that the number of crescents on her finger she looked at online could reflect a person's health status . The fewer crescents, the worse the health. After hearing this, Aunt Zhao counted herself and found that there were only four crescent moons, and she immediately panicked.
After returning home, Aunt Zhao was still thinking about this matter. The more she thought about it, the more scared she became. She went to the hospital for a checkup the next day. The results showed that everything was normal. Aunt Zhao was in good health and had no disease.
Although this result made Aunt Zhao feel relieved, she was still very confused about why some people have crescents on their nails and some don't. Does this have anything to do with health?
I believe that many people have discovered the crescent moon on fingernails and , and have more or less questions about it. Today, I will help you answer them one by one through this article.
Why do some people have crescents on their nails and some don’t? How many teeth are the healthiest?
I believe that many attentive people have discovered that there are some white crescent-like traces on the bottom of their fingernails, and are curious about what they are. Some people may have heard that crescent-like marks are related to their health. The more crescents there are, the healthier they are. However, are these claims really credible? Do they have scientific basis?
The white marks on the bottom of fingernails are also called half-moon marks, half-moon white , and some people call them little moons. In short, has various names. However, no matter what its name is, we need to know that it is because our body is undergoing metabolism all the time, and the fingernails will also grow accordingly. At this time, the bottom of the finger will appear white because there are no blood vessels passing through it.
In addition, the cells in the middle of the bottom of the fingernail grow faster, and the cells on both sides grow slower, so it will form a shape that is high in the middle and low on both sides, resembling a crescent moon.
Then why do some people have more crescents on their fingernails, some people have less crescents on their fingernails, and some people even have no at all?
This is because the growth rate of fingernails is closely related to the growth rate of nail matrix cells , and the growth rate of nail matrix cells is affected by age, environment, nutritional status and certain diseases. Therefore, each person's nail crescent is different, and the number is also different.
Some people have also heard that the number and presence of crescents on fingers is related to physical health. People with more crescents are healthy, while people with fewer crescents are unhealthy.
Actually, this statement is not very accurate. We cannot judge whether the body is healthy simply by the number and size of the crescents. This depends on the situation.
First of all, we have to remember one sentence, only has an invisible crescent, there is no non-existent crescent , as long as there are nails on the fingers, there must be crescents, but some crescents are not shown and cannot be seen.
Whether our eyes can see the crescent moon and the size of the crescent moon are related to the frequency of use of fingers in daily life. If the fingers are used more frequently, the nails will be more stimulated, so the nails will grow faster, and the crescents at the bottom of the nails will be easier to show and be seen by people.
This is why most people have crescents on their thumbs, and the crescents on the thumb are larger than the crescents on other fingers. The little finger is because the frequency of use is relatively small and it does not receive much stimulation. Therefore, the crescent at the bottom of the little finger nail grows more slowly, and the crescents are relatively rare.
Therefore, we cannot simply judge whether the body is healthy by the number and presence of crescents on our fingers.
I mentioned above that the size and growth rate of crescents are closely related to the body's metabolism. Therefore, the number and size of crescents can indeed reflect changes in body metabolism to a certain extent. However, what should be noted here is that the comparison of the crescent moon is not to compare with others, but to compare with the previous crescent condition of your own finger.
For example, if you could barely see crescents on your fingers before, but now you suddenly find them appearing, or if you only had one or two crescents on your fingers before, and suddenly there are many more crescents in a short period of time, you should pay attention at this time, it may be related to hyperthyroidism .
This is because hyperthyroidism will greatly increase the body's metabolic rate , and the rate of nail production will also increase accordingly. Therefore, the crescent moon will suddenly become obvious or the number will increase in a short period of time. At this time, if you still have symptoms such as increased appetite but lighter weight, difficulty falling asleep at night, rapid heart rate or irritability, excessive sweating and fear of heat, you should go to the hospital for examination as soon as possible.
In addition, if the body is malnourished, or if the nails are damaged, the cells at the bottom of the nails will reduce the amount of keratin produced due to lack of nutrients, causing the crescents to fade or disappear.
Moreover, as we grow older, our body's metabolic rate will slowly decrease, and the crescent moon may gradually decrease or disappear. Therefore, some middle-aged and elderly people cannot see the crescent moon or there are very few crescent moons on their fingers. This is also a normal phenomenon, so there is no need to panic.
It can be seen from this that we cannot judge whether the body is healthy simply by the number and size of the crescents. We should compare it with the crescents on our previous fingers to find out the problem. But, you know what? In addition to the crescent moon on the fingers, abnormalities in the body can also be seen from the abnormalities in the fingernails. What is going on?
Be wary of abnormal nails. If the following symptoms appear, you should pay attention.
Before talking about abnormal nails, we should understand what normal nails look like. Generally speaking, if a person is healthy and well-nourished, his nails will be hard, smooth, rosy, and shiny . When you press the top of the nail hard and then release it, the blood color will return immediately.
looks like some abnormal nails, such as spoon-shaped fingers, club-shaped nails , horizontal groove nails , etc., which indicates that there may be a problem with the body and requires attention.
Let's first talk about spoon refers to . As the name suggests, spoon-shaped nails are nails with a hollow in the middle and raised edges on all sides, resembling a spoon. This is due to nutritional disorders of the nail tissue and abnormal development of the nail bed.
It is more common in iron deficiency anemia , altitude sickness, thyroid dysfunction, syphilis , rheumatic fever , etc. It may also be caused by insufficient blood supply to the nail bed due to long-term squeezing and pressure due to work that uses force on the fingertips.
Followed by clubbed nails , which is an abnormal thickening of the soft tissue at the end of the finger. The nails are highly curved both vertically and horizontally. The base angle between the skin on the back of the fingertip and the nail plate is greater than 180 degrees, which looks like a wooden fish . It is called clubbing in medicine.
Finger clubbing is a characteristic manifestation of chronic hypoxia. Expert studies have found that most patients with cardiopulmonary diseases do not absorb enough oxygen. When red blood cells flow through the fingertips, they often cannot release all the oxygen contained in them, resulting in hypoxia in the fingertips and local hypertrophy.
Clubbing occurs in patients with inflammatory diseases and malignant tumors . This is due to the increase in fibrinogen and globulin in the blood, which causes the red blood cells to form linear shapes, reducing the external contact surface of the red blood cells, thereby causing hypoxia.
Clinical statistics show that about 75% to 80% of clubbing occurs in patients with pulmonary disease, 15% of cardiovascular disease, and the remaining 5% of blood, endocrine , neurological and other system diseases.The study also found that finger clubbing occurred in 66% of cases that died of subacute bacterial endocarditis.
Finally, there is horizontal groove nails , which means horizontal stripes appear on the nails. If a person has a horizontal groove on 10 nails, it can be inferred that he must have suffered from a serious acute illness not long ago.
Because when a person is seriously ill, the growth of nails is inhibited by and grows slowly and thinly. After recovery, the growth of nails returns to normal, leaving a horizontal groove. This situation is more common in measles , mumps , heart disease sudden etc.
Therefore, if you have abnormalities such as spoon-shaped nails, club-shaped nails, and transverse groove nails on your fingers, you should pay attention to your body, because these nail abnormalities may represent physical problems. You should go to the hospital for relevant examinations as soon as possible. If no problem is found, everything will be fine. If a problem is found, early detection and early treatment can be achieved.
is written at the end
All in all, simply looking at the number and size of the crescents on your fingernails doesn't mean much, but comparing it with the previous crescents can reveal some problems. In addition, we should also pay more attention to other symptoms on the nails, because the health of the body can also be judged from the nails. So when we find that the nails have the above-mentioned conditions, we need to pay more attention to it. It is best to go to the hospital for a check-up.
