Nails and health

[edit]

White spots, horizontal lines, vertical lines, small sun ......

Sneak up on the original smooth nails,

You think they affect only your beauty?

Unbeknownst to you, they are a health warning to you!

The Chinese medicine believes that the nails for the internal organs of the qi and blood of the external glory, and the body's internal organs and meridians have a direct link to fully reflect the body's physiological and pathological changes. As introduced by Zhu Dingcheng, deputy director of Shanghai Huadong Hospital massage, by observing the shape, size and color of the nails can reflect the basic state of a person's health, and even see his potential health crisis; and through the changes in the nail luster, lines, spots, etc., can be deduced that the body is quietly occurring lesions. Therefore, learning to observe the nails, is to learn a most simple health self-testing method.

Different nail shape, different physique

Nail shape mainly includes the ratio of nail length and width and the shape of the nails in these two aspects, because the nail shape is mostly related to congenital genetic factors, so from the shape of the nails on the most likely belong to the differences in their own physique.

Proportions

Long shape: people with long nails are gentle and not impatient, so illnesses caused by mental stimulation are less common in them. However, because the innate constitution is relatively weak and the immune system is poor, it is easy to suffer from acute inflammatory diseases, such as upper respiratory tract infections, gastroenteritis, as well as diseases of the brain and chest.

Short shape: people with short nails are more prone to impatient and impulsive character. These people are born with a weak heart and are prone to diseases of the lower body, from the abdomen to the waist, as well as the legs and feet. If the tips of the nails are flat and embedded in the flesh, they are more prone to neuralgia and rheumatism.

Square: the length and width of these nails are close to each other, and the nails are close to square, this kind of people's physical condition is relatively poor, often belong to the type of weakness, although there is no obvious disease, but it is very easy to become a lot of hereditary disease patients. If a woman has such nails, she should be alert to problems in the uterus and ovaries.

TIPS: The healthiest ratio of nail length to width should be 4:3.

Shape

Lily shape: The nails are long, with a pronounced protrusion in the center and an inward curvature around the periphery, and are shaped like pieces of a lily. This type of nail is mostly seen in women, this nail shape is the most beautiful, but people who have this nail are more likely to be sickly since childhood, especially in the digestive system is often prone to problems, but also more likely to suffer from blood system diseases.

Fan-shaped: These nails are narrow at the bottom and wide at the top, and the ends of the fingers are curved. People with fan-shaped nails, most of them are born strong physical type, from childhood physical fitness is very good, strong tolerance, but they are very easy to ignore their own health. In adulthood or old age is more likely to suffer from duodenal ulcer, cholecystitis and even liver disease.

Round: With rounded nails, the owner looks fit and healthy and rarely gets sick. These people are very insensitive to the reaction of disease, it is difficult to self-awareness of the body's abnormal conditions, so, once sick, often very heavy. They are most prone to bleeding ulcers, pancreatitis, heart disorders and even cancer.

Different nail color, different warning

Nail color is about the gloss and color of the nail. A healthy person's nails have a certain luster and are very even, like a piece of smooth glass, and they should be a beautiful pink color. Once the nail color changes, it means that something has gone wrong in the body and should be taken seriously.

Shine

Shiny nails:

There are two types of shiny nails. One is that there are blocks or strips on the nails that become shiny, not the whole nail, which is mostly related to pleurisy and the presence of fluid in the abdominal cavity; the other is that the whole nail becomes shiny as if it is coated with oil and the nails become thinner, which is mostly seen in patients with hyperthyroidism, diabetes mellitus, and acute infectious diseases.

Uneven luster:

Uneven luster of the nails can be manifested in different nails or in different parts of the same nail. If each nail is shiny at the front end and the root is hairy and shapeless, chronic bronchitis and cholecystitis may be present; if only some of the nails are unevenly shiny, it implies that there is some chronic damage and inflammation in the body.

Loss of luster:

If the whole nail is like hairy glass, without a trace of luster, it suggests that there are certain chronic wasting diseases in the body, such as tuberculosis, etc.; and if there are serious wasting diseases in the body, such as liver abscess, lung abscess, or patients with long-term chronic hemorrhage, will also appear in this situation.

Color

White nails: pale nails, lack of blood, mostly in malnutrition, anemia; in addition, if the nails suddenly become white, it is common blood loss, shock and other emergencies, or hookworm disease, gastrointestinal hemorrhage, advanced tuberculosis, pulmonary heart disease and other chronic diseases. It is important to note that if the nails are white like hair glass, it is a characteristic of cirrhosis of the liver.

Nail color gray: nails are gray, mostly due to lack of oxygen, generally more common among smokers; for non-smokers, nails suddenly turned gray, the biggest possibility is suffering from onychomycosis, the edge of the nails at the beginning of the itchy, and then the nails will also be deformed, lose their luster and become gray-white, such as gray nails, and so on.

Nail color yellow: nails yellow, in Chinese medicine, think more by the hot and humid fumigation caused by the common hypothyroidism, carrot blood, nephrotic syndrome, etc.; Western medicine on the nails are thought to be yellow half with the body of vitamin E deficiency. If all the nails are yellow, it is necessary to receive treatment, because it is a symbol of the whole body weakness.

Different concave changes, different diseases

Nail concave change, refers to the nails on the appearance of some horizontal lines, vertical lines and spots and so on. Chinese medicine points out that such changes in the nails are closely related to the low function of the body's tissues and organs, and pathological changes such as the destruction and atrophy of tissue structure.

Vertical lines: The surface of the nail is not smooth enough, and a straight line appears, usually after overwork and overuse of the brain; these vertical lines will be clearly visible when there is not enough sleep. If the vertical lines persist, it may be a chronic lesion of the organs in the body. If they are not regulated, the nails will become high and low as the condition develops and may even split.

Horizontal lines: Horizontal lines on the nails are a kind of record of lesions that have occurred. In other words, when there are horizontal lines on the nails, some lesions must have already appeared in the body. Generally speaking, at the beginning the horizontal lines are only at the very bottom of the nail, and as the nail grows, it gradually moves upward, which signals that it is getting closer to the onset of the disease.

Spots: a small number of white spots on the nails is usually a sign of calcium deficiency, silicon deficiency or parasitic disease; a relatively large number of white spots may be a sign of neurasthenia; and the presence of yellow fine spots on the nails may be suffering from digestive diseases; if black spots appear on the nails be careful, the lighter ones are just overworked and malnourished, while the heavier ones may be the precursor of gastric ptosis, gastric cancer and uterine cancer.

Generally speaking, the nail half-moon accounts for 1/5 of the entire nail is the best state, too big or too small or hidden are not normal. If the nail half-moon is too big, people are prone to high blood pressure and stroke; if the nail half-moon is too small, it means the blood pressure is too low. People who can not see the half-moon nail, most of the symptoms of anemia or neurasthenia.

Healthy nails should be smooth and clean, no longitudinal and transverse grooves on the surface of the nails, no interference spots on the nails, nails symmetrical, not skewed, no depression or the end of the phenomenon of upward cocking. As far as normal nails are concerned, although there are many types of nails, there are actually no identical nails.

These are the most common types of nails.

The growth and shape of the nails are always affected by changes in the body. Especially from the color of the nails, with or without normal human nail white, you can see whether I am healthy or is pregnant with disease. In addition, from the following 10 different kinds of sick nails can also see some clues. This should be paid attention to, and take the right approach, and strive for early correction.

Nails brittle, cracked

First of all, we should find out the cause of its pathology: First, the nails are in contact with water for too long; Second, the dietary protein and calcium, sulfur, zinc and other elements or vitamins A, B, C is insufficient; Third, the chronic diseases or emotions in a state of stress; Fourth, oral contraceptives; Fifth, the nails are polished or use of abrasive agents caused.
