What does it mean when the half-moon disappears?

As people's living standards improve, everyone's health awareness is getting higher and higher. Many people usually observe their bodies carefully. Some people find that the half-moons on their hands disappear at a certain stage, but sometimes there are many half-moons on their fingers. In fact, if the half-moons disappear, it is very likely that the body is in a sub-healthy state. At this time, you need to supplement more nutrients and eat more high-protein foods.

The relationship between the half-moon on the nails and human health

Adults grow 1-1.4 mm per week. Growing too fast or too slow may be a disease. Some people say: When a person is idle, his hair grows longer; when a mind is idle, his nails grow longer. Although there is no definite basis for this statement, the growth rate of nails does vary throughout the year. In addition, Chinese medicine believes that nails are the extension of tendons and the external sign of liver and gallbladder, so everyone's nail growth rate is not exactly the same, it is closely related to a person's health status. Although the growth rates of the nails of the five fingers are different, the growth rates of the nails on the left and right hands are generally the same, and there is no obvious difference due to right-handedness or left-handedness. Therefore, the crescents on the two fingers are basically symmetrical.

A person may occasionally have one more or one less half-moon. This is just a normal change in the body's metabolism that causes a slight change in the growth rate of the nails. There is no need to worry. But sometimes, changes in the crescent can indeed reflect some health problems. The premise is - your crescent moon just becomes very different from what you had before! It's not that your crescent moon is different from others.

If in a short period of time, you go from having no lunula to having many full lunulae, or if your originally full lunulae suddenly disappear, you should be careful that there may be something wrong with your thyroid gland.

Hyperthyroidism will speed up the metabolism of the whole body, and nail growth is no exception. Therefore, there will be a lot of keratin that is already a little hard but has not yet faded to translucent. In this way, people who have no lunula will have a full lunula, and people who have a lunula will have its lunula become bigger and bigger.

A widely circulated saying: A healthy person must have a crescent on the thumbs of both hands, the index finger and middle finger should have a crescent, and the ring finger does not have a crescent. It is best to have eight to ten crescents on both hands. Generally speaking, if the thumb, index finger and middle finger all have half-moons, a total of six half-moons, it is considered basically healthy.

Expert interpretation: It can be used as a reference to determine the coldness or heat of the body, but it cannot be used to diagnose diseases

The director of the Department of Integrated Traditional Chinese and Western Medicine of the 421st Hospital of the People's Liberation Army believes that the scientific name of the half-moon is the nail half-moon or the half-moon mark. It is a white thing like a crescent moon, smaller than a semicircle, near the root of the nail. Traditional Chinese medicine believes that nails are the receptacle of the liver, and the liver qi and blood in the body are closely related to the nails. Certain changes in the body will also be reflected in the nails. For example, white nails may indicate anemia, and a large number of lunulae may indicate a hot constitution. However, there are many causes of disease, and one cannot assert disease based solely on changes in nails, and one cannot use the number, size, and position of lunulae to judge whether the body is healthy.

In traditional Chinese medicine, the number and size of crescents do not indicate whether the body is healthy, but is one of the manifestations of the cold or hot constitution. Under normal circumstances, most people have three to five lunulae. If the number of lunulae is too small (less than three or none) and they are very small, the person's constitution is generally cold. If the number of lunulae is large (more than six) and they are larger, the person's constitution is generally hot. The crescent can be used as a reference for determining the coldness or heat of physical constitution, but it cannot be relied upon entirely to diagnose and treat illnesses, because the coldness or heat of physical constitution is different from the coldness or heat of the disease. A person with a cold constitution can suffer from hot diseases, and a person with a hot constitution can also suffer from cold diseases.
