Rumor: Vertical stripes on the nails, a sign of serious illness? Crescent moon represents health? tell you the truth

“There are vertical lines on the nails. I heard that it is a sign of serious illness. Is it true?” The backstage received a private message from a fan.

I believe that many people will find that there are vertical lines on their nails, which are not very smooth. There are indeed many comments on the Internet that long vertical lines on the nails represent a physical problem. Is this true?

1. There are vertical lines on the nails, which means there is a problem with the body?

The fingernails reflect the health of the body. What is the connection between the nails and our body?

Nails are actually formed by the keratinization of the base of the nail root, and the growth of the nail root is a continuous metabolic process. The surface of normal nails is smooth and pink, without very obvious changes in color and texture.

Some people say that vertical lines on the nails are a sign of serious illness. In this regard, Wang Qian, Department of General Medicine, Run Run Shaw Hospital said that the long vertical lines on the fingernails are actually just “traces” of the years. Vertical lines are to the nails what wrinkles are to the skin. They have always existed, but the lines will become more pronounced with age.

But everything is true. However, If the vertical lines are very obvious, the lines are particularly deep, or the vertical lines become horizontal lines, it is necessary to Considering the possibility of liver disease, diabetes, and acute fever, it is best to go to a specialist hospital for a definite diagnosis at this time.

Second, extended reading: nails without crescents are also signs of serious illness?

In addition to the lines on the nails, the crescent moon is often regarded as the basis for good health. There are rumors that people with fewer crescent moons tend to be weaker and more prone to disease.

The so-called “crescent moon” is the half-moon mark on the nail, and some people call it the little sun. Its production is a natural phenomenon of human metabolism. At the lower end of the nail, white marks form where no blood vessels pass, and the shape of a crescent is formed due to the slow growth of cells on both sides. As the nail grows along the nail bed, it becomes a near-transparent color.

Whether the crescent crescent is big or small, and whether it reflects the individual’s physical condition depends on the specific influencing factors:

< p>1. The crescent moon may be “hidden”

As long as there are nails, there must be a crescent moon. It’s just a crescent moon that is invisible to the naked eye, which may be related to the frequency of finger use. The more used nails are, the more irritated they are, the faster they grow, and the easier the crescent moon is to show. Therefore, most people have a crescent on the thumb, and the crescent on the little finger is relatively rare.

2. Insufficient nutrition of the body

When there is severe malnutrition or trauma to the nails, the bottom of the nails cannot get sufficient nutrition and cannot produce horns. Protein cells, then the crescent is also likely to disappear.

3. Metabolism-related

The crescent moon is a new cell in the body, and its size and growth are closely related to metabolism, so it can indeed reflect some changes in metabolism . For example, in patients with hyperthyroidism, due to the rapid metabolism, the patient will have a sudden increase in the number of crescents in a short period of time.

Third, Focus: When these conditions occur on the nails, you should worry about diseases or even cancer

< p> It is often said that paying attention to the nails can find “clues” of certain diseases in the body, so what changes on the nails are we really need to be vigilant about?

1. Long stripes on the nails

The stripes on the nails, also known as Bauer’s lines, will grow with the nails And move. If it’s just a very shallow line, don’t worry. However, if it is a very obvious horizontal groove, it is a sign that you have severe malnutrition in your body, or some serious medical condition that temporarily affects nail growth, such as measles, mumps, heart disease, liver disease strong> etc.

2. Nails with long black vertical lines

This situation is called “black nails” There are two main reasons for the formation of this type of black nails, one is Inner and pigmentation of the nails, leading to localized blackening, the second type may be nail matrix freckles moles generally do not need deliberate treatment, but if the pigmentation of the black nails is uneven and the shape is irregular strong>, it should be considered to be caused by melanoma.

3. The nails are abnormally curved downwards

This kind of nails are called “clubbing fingers”. The nails are a bit like cat’s nails and will hook downward. , the fingers will also be swollen. “Club-shaped fingers” are a common sign of certain diseases: 80% are seen in lung disease, 15% in cardiovascular disease, and 10% in digestive and other diseases.

4. The nail is half white and half red

This kind of nail is called “Lindsay’s Nail”, a distinct color of the nails>, pressing the nails hard will not change. This type of nail is more common in patients with chronic kidney disease.

Of course, the appearance of the above mentioned nail changes does not mean that it is a disease or cancer. It may also be a temporary change in the nail due to certain factors. It is recommended to go to the hospital for diagnosis when similar to the above-mentioned changes in the nails.

Fourth, how to protect your nails?

A pair of beautiful hands will indeed make a good first impression on the other party. How should we maintain our nails in our daily life?

1. Moisturizing

If you want to maintain your nails, the first thing you need to do is to moisturize your hands. Moisturizing can be done by rubbing nail polish or using skin cream. First, soak your hands in water to clean up the dead skin around the nails, and then use oil or skin cream to moisturize around the nails.

2. Stop it, don’t cut it randomly

Dead skin is easy to gather near the nails, so don’t cut it randomly, otherwise it will easily hurt to the root of the nail, resulting in uneven edges of the nail. When cutting your nails, it is best to leave some free margins.

It is unscientific to judge physical health only by the nail pattern and the number of crescent moons. When you encounter special nail changes and your body feels obvious discomfort, you may as well consult a specialist instead of diagnosing yourself. “Scared” half to death.
