Changes in the five internal organs of human beings will be reflected on the nails accordingly. As long as you pay attention to the subtle changes in your nails, you can predict a person's health status. If you look at your nails to judge your health, the key lies in the color and shape of your nails. Healthy nails should be smooth and smooth, with no vertical or horizontal grooves on the nail surface, no interference spots on the nail surface, symmetrical nails, no deflection, no depressions or upturned ends. Although there are many types of normal nails, they are not exactly the same. Generally speaking, healthy nails can be divided into: ordinary nails, large nails, small nails, long nails, short nails, wide nails, narrow nails, etc. Usually the nails take up less than 3/5 of the finger, and are arched in a rectangular shape. The transverse diameter of the top is slightly larger than the transverse diameter of the base. The white half-moon-shaped part at the base of the nail is called the nail half-moon, which is also commonly known as nail white. It is located symmetrically in the center of each finger. , no big offset. Speaking of which, when all fingernails have the proper white color, it can be inferred that the human body is in good health. If 10 fingernails have no or only a little bit of nail white, it means that the body is exhausted or suffering from illness. The ideal white nail should account for about 1/5 of the nail area. A large white nail or no white nail does not mean that the body is very strong. The growth and shape of nails are affected by changes in the body at any time. Especially from the color of the nails and the presence or absence of normal white nails, you can tell whether you are healthy or pregnant with disease. In addition, some clues can also be seen from the following 10 different kinds of sick nails. We should pay attention to this and adopt correct handling methods to strive for early correction. 1. The causes of brittle and cracked nails should first be identified: first, the nails are in contact with water for too long; second, insufficient protein, calcium, sulfur, zinc and other elements in the diet or vitamins A, B, and C; third, chronic diseases Or the mood is in a state of stress; the fourth is oral contraceptives; the fifth is caused by polishing the nails or using abrasives. You may wish to adopt the following correction methods respectively. 1. Take two tablespoons of yeast and 1,000 mg of choline orally every day. It is best to add these nutrients to fluid or milk and take them orally. This will help improve the strength of nails. 2. Since lack of iron can cause dry and brittle nails, it is best to eat more iron-rich foods and take vitamin C to improve the ability to absorb iron. 3. Soak your nails, which have been polished and have no defects, in warm wheat germ oil or other natural oils for about 5-10 minutes every day, and then massage from the fingertips to the surface cuticle. If you use an emery board to slightly abrade the nail surface, it will allow the oil to penetrate more easily. 4. Soak your fingers in dilute vinegar every night. This is a good way to prevent nails from easily splitting. White iodine used on the top of the nail and under the tip of the nail can not only restore the flexibility and strength of the nail, but also hinder the segmentation of the nail. 2. Nails turn fishy or gray. A person suffering from chronic diseases, long-term emotional depression, smoking, or fingers coming into contact with chemical contaminants such as carbon paper and hair dye can cause the nails to change color or stain. If your nails are heavily stained, it may be better to wait until new nails grow back. If you want to remove surface staining in time, you can rub a piece of lemon on your fingertips repeatedly, then wash and dry. 3. Nails grow in strange shapes. If there is a long-term lack of protein or iron, it is usually easy to cause spoon-shaped or flat nails, which can be corrected by improving diet and nutrition. It is said that wearing artificial nails can help the nails store moisture and become soft, causing the nails to bend upward. To solve this problem, you should increase nutrition and remove the artificial nails as appropriate. 4. Nails are dull. If the nails are wavy and dull, it may indicate a lack of protein, a lack of vitamins A and B, or a lack of minerals. For this, you can improve your daily diet and supplement with multiple vitamins every day. Add 15 grams of vitamin B6 and zinc. Nails that are dull and completely white indicate that you may be suffering from liver disease. At this time, you can ask a physician for examination and treatment. 5. Pale nails This may be a sign of zinc deficiency and vitamin B6 deficiency, or it may be caused by anemia. If the symptoms of pale nails persist even after improving your diet and nutrition, you should seek advice from your doctor to find out the cause. 6. Nail dents: This type of nail disease indicates a lack of calcium, protein, and sulfur elements in the body. These nutrients can be obtained from eggs and garlic, and it is best to eat them regularly. 7. Ridged, grooved and grooved nails If you wear artificial nails or do not pay attention to trimming the cuticles on the surface, you can cause ridged, pitted and grooved nails. These abnormal signs may be caused by disease or nutritional deficiencies, so they must be treated symptomatically. 8. Line-like raised nails. This kind of strange and beautiful-looking nails often occurs after a bad mood or illness. If you can eat a proper diet rich in protein every day and take vitamin C plus 15 mg of zinc supplements at the same time, you can accelerate regeneration. The growth of nails can cause the horizontal raised lines of nails to gradually disappear. 9. Vertical grooved nails sometimes only occur after the age of 40. This is due to the weakened cell regeneration ability. For this reason, you need to check at least once a year to see if there is anemia or lack of vitamins and minerals. situation. This condition may reveal a deficiency in vitamin A, calcium or iron. 10. Soft and weak nails. This type of unhealthy nails is often caused by excessive contact with water or chemicals in nail cosmetics.

Secondly, it is also related to poor mood and poor diet. You might as well eat more sunflower seeds in your daily life to increase your vitamin A intake. In addition, 5000 mg of dolomite can be taken orally every day. It is reported that this product can supplement calcium and magnesium, and can restore soft and brittle nails to normal and look brand new within 3 weeks.

How to measure health with fingernails

It is not idealistic to measure a person’s health by looking at fingernails. A person must have good nutrition so that nails can grow normally, otherwise there will be some abnormal phenomena, which doctors can often diagnose important diseases. The following introduces several abnormal nail phenomena:

1. Clubbing: The nail is markedly arched upward and curves around the finger. Nail clubbing may indicate emphysema, tuberculosis, cardiovascular disease, ulcerative colitis, or cirrhosis.

2. Blue Crescent: A crescent-shaped white mark at the base of the nail with a blue halo may indicate any of the following conditions: blocked blood circulation, heart disease, Raynaud's syndrome, vasospasm of the fingers and toes, usually Due to exposure to freezing. But it is sometimes associated with rheumatoid arthritis or the autoimmune disease lupus.

3. Spoon-shaped nails: The middle of the nail sinks and the entire nail becomes flat or spoon-shaped. This kind of nails is related to iron deficiency anemia, syphilis, thyroid disorders, rheumatic fever, etc.

4. Lindsay's nails: The half of the nail near the nail tip is pink or brown, and the half near the nail is white. This type of nail is also called a double nail and may be a sign of chronic renal failure.

5． Beau's lines: The appearance of horizontal grooves on the nails indicates malnutrition or some serious disease that will temporarily affect the growth of the nails, such as measles, costalitis, and heart attack.

6． Telley's nails: Most of the skin under the nail turns white, leaving only a small area near the tip of the nail that still appears pink. This may indicate cirrhosis of the liver.

7. Yellow Nail Syndrome: Nail growth slows down and becomes thicker and harder; it turns yellow or green. Causes include chronic respiratory disease, thyroid disease or lymphadenopathy.

8． Bleeding: If these vertical red lines appear on the nails, they indicate capillary bleeding. If multiple such blood lines appear, it may indicate chronic hypertension, psoriasis, or a fatal infection called subacute bacterial endocarditis. .

9. Irregular pits: Many psoriasis patients have this phenomenon.

10. Rows of pits: The surface of the nails becomes like the surface of copper hammered by a coppersmith, sometimes caused by alopecia areata. This is an immune disease of the body that is poorly understood by the medical community and can cause partial or complete hair loss.

11. Brown or dark spots: This type of discoloration, especially if the nail expands into the surrounding finger tissue, may indicate melanoma. They may appear as a single large patch or as a cluster of tiny spots, and they most commonly appear on the thumbs and big toes.

There are usually two conditions for vertical lines on nails:

The nail ridge deck is thin and brittle, with longitudinal ridge-like protrusions. The distal end is often broken and branched due to nutrition. Caused by adverse effects, it can also be seen in patients with lichen planus, alopecia areata and other diseases.

The longitudinal groove of the nail typically has a longitudinal ridge in the center of the nail plate, and the top of the ridge is sunken into a shallow groove. It can also have no ridge but a significant groove. It is often caused by damage to the nail matrix and can also be seen in For patients with diseases such as lichen planus, it is a manifestation of allergy.

To detect your disease in time, please always pay attention to your hands, it may be warning you

Nails and disease prediction

Nails The analysis began in ancient times. Doctors of the Hispanic school advocated the nail analysis method, which is still used today, but most people don't know that small nails can truthfully reflect the health of the human body.

The back of the nail rises very high upward, while the surrounding area of ??the nail curves downward in an arc shape. Nails of this shape may indicate emphysema, tuberculosis, cardiovascular disease, ulcerative colitis, cirrhosis of the liver.

A blue crescent at the base of the nail may indicate one of the following conditions: compromised blood circulation, heart disease, Reynolds syndrome - spasm of arteries in the fingers and toes, which is often extreme Caused by cold and sometimes associated with rheumatoid arthritis or the autoimmune disease lupus erythematosus.

Nails that are sunken, flat, or spoon-shaped. This is associated with iron deficiency anemia, syphilis, thyroid disease, and rheumatic fever.

Lindsay nails (also called two-tone nails). The half near the tip of the nail is pink or brown, and the half near the protective film is white. Such nails may be a sign of chronic kidney failure.

The nails have deep parallel grooves. This is caused by malnutrition or any serious disease that temporarily prevents nail growth, such as measles, pancreatitis, heart disease, and carpal tunnel syndrome.

Most of the skin under the nails is white, and the normal pink area on the fingertips is reduced and becomes band-like. Such nails may indicate cirrhosis of the liver.

Nail production slows down, and the nails become thickened, hardened, and turn yellow or yellow-green. Causes include chronic respiratory, thyroid or lymph gland disease. This longitudinal streak of blood indicates capillary bleeding. Many bloody streaks may be a sign of chronic hypertension, psoriasis, or potentially life-threatening subacute bacterial endocarditis.

Most patients with psoriasis have such irregular and deep nails.

The deep pits in the nails that resemble hammered brass are caused by alopecia areata - an autoimmune disease that causes partial and total hair loss.

Both color nails, especially nails that extend from the nail to the surrounding tissue and are brown or black, may be associated with malignant melanoma. They may be one large spot or a patch of small spots. Symptoms are most likely to appear on the thumb and big toe.

Abnormal nails and main diseases

A normal nail is half of the third phalanx of the finger, neither wide nor narrow, elastic, not easy to break, has a certain hardness, and the edge is The flesh is parallel, light red, shiny, without spots or bumps.

If the nail is less than half of the third phalanx, it is usually due to physical weakness, weight loss, digestive system dysfunction, but strong disease resistance. People with soft nails have poor energy, are prone to fatigue, like to sleep, have poor disease resistance, and are often withered and sluggish. People with hard and brittle nails often suffer from anemia and loss of appetite. White spots or mica-like spots on the nails indicate a lack of trace elements such as calcium and silicon, as well as parasites. Such people are prone to nervousness, irritability, and habitual constipation.

The light-colored arc-shaped circle at the root of the nail is called the half-moon arc, commonly known as the health circle. The normal healthy circle covers about -1/5 of the nail and has no shadow. The width and size of the health circle vary from person to person and race to race. Generally, the health circle is about 3 mm for men and slightly smaller for women. The width of the index finger, middle finger, and ring finger decreases in descending order, and is mostly absent on the little finger. It is narrower in the elderly and often disappears in malnourished people. Changes in the health circle can best indicate the nutritional status of the body and are a reminder light of the nutritional status of the human body.

Nails - barometer of health

Nails are a barometer of human health. Normal nails are ruddy and subtle, tough and curved, smooth and shiny. The half-moon at the root of the nail is off-white. If the shape and color of nails vary, it indicates that the human body may be suffering from a certain disease. Here is some common sense about observing nails:

Judging from the shape of nails: nails are flat, sunken, spoon-shaped, brittle and fragile. Light is a sign of insufficient liver water or iron deficiency anemia, hypochromic anemia and light microcytic anemia. The nails are parrot-shaped and the finger tips are like drumsticks. They are more common in congenital heart disease with cyanosis, rheumatic heart with chronic heart failure and lung abscess, emphysema, silicosis, chronic fibrocavitary tuberculosis, and chronic ulcerative disease. Colitis and other symptoms. The appearance of horizontal lines on nails is a sign of kidney disease or myocardial infarction; the appearance of vertical lines, a sign of lack of vitamin A, is a sign of liver disease; the appearance of indented pit lines is a sign of poor respiratory function.

Judging from the color of the nails: the nails turn white, and the acute symptoms are seen in blood loss and shock; the chronic symptoms are seen in anemia, hookworms and gastrointestinal bleeding, late stage tuberculosis, pulmonary heart disease, etc.; if the nails are as white as ground glass If the same, it is a characteristic of liver cirrhosis; whitening, thinning and soft nails are more common in chronic wasting diseases; yellowing of nails is due to lack of vitamin E. Traditional Chinese medicine believes that it is mostly caused by damp and hot fumigation, and is common in hypothyroidism and carrotemia. , nephrotic syndrome, etc. When the nails turn gray, they are suffering from onychomycosis. In the initial stage, the nails are itchy, and then the nails become deformed, lose their luster and become grayish white. Blue and purple nails accompanied by small red spines are caused by hypoxia and indicate that the nails are half red and half white (commonly known as yin and yang nails), indicating poor kidney function. The appearance of white spots or flocculent white spots on nails may be due to zinc deficiency, gastrointestinal disease or anemia; the appearance of black spots or livedo is a sign of poisoning; the appearance of erythema around the nails is more common in patients with lupus erythematosus and dermatomyositis. If the nail half moon is blue, it means poor peripheral circulation; if it is obviously red, it is a sign of heart failure; if the nail half moon is obvious, the intestinal absorption is good; if it is absent or narrow, the digestion ability is poor.

Nails are indeed a window to observe human health, so we should always pay attention to its changes, especially those who have long-term manicures. Don’t forget to give your nails a holiday every once in a while to let them show their true colors. If multiple nail changes are found, you should seek medical attention promptly; if only one or two nails have changes, there is no need to panic, as it may be caused by trauma.

Fingernails should be pink, shiny, moderately thick, moderately hard and soft, not easily broken, with a smooth surface, and a healthy ring (half-moon shape at the bottom of the nail) accounting for one-fifth of the length of the nail (preferably five nails) is a sign of health. If the color is pale, yellow, cyan, black, dull, too thick or too thin, too soft or too hard, easy to break, rough and dull surface with grooves, vertical stripes, white spots, and abnormal proportion of healthy circles, it is usually A sign of poor physical fitness.

Pale ends of the fingers indicate deficiency of both Qi and blood, and dark purple indicates blood stasis. People with square fingers are prone to stone disease. People with the spoon finger mostly have a constitution with yin deficiency and yang hyperactivity, and are prone to stroke, chest numbness, diabetes and other diseases. When some hypertensive patients extend their fingers, their fingers tilt toward the thumb side.

Nails should be healthy. Nails that are like hammers indicate incompetence. White nails indicate deficiency of Qi and blood, black nails indicate severe disease, and yellow nails indicate fumigation due to dampness and heat. If the basic color does not disperse when pressed, it is blood stasis. If the color does not persist for a long time, it indicates blood deficiency and qi stagnation. People with white spots often have parasites, are prone to fatigue, or have long-term constipation.

Those who have a health circle that is too large are likely to suffer from hyperactivity of liver yang and have a stroke; those who have a health circle that is too small are likely to suffer from gout, cough, gastroenteritis, peptic ulcer and encephalomalacia (which may become indistinct after a stroke); those who do not have a health circle are mostly suffering from Deficiency of both Qi and blood; those with many marks and grooves on the nail surface are parasites and spleen deficiency. If it occurs on the thumb, the person will feel tired; if it occurs on the index finger, it is prone to skin diseases; if it occurs on the middle finger, it is mostly impotence; if it occurs on the ring finger, it is susceptible Cough, eye disease; those who occur in the little finger are prone to throat disease, wind paralysis, damp heat and yellowing.

Too weak nails are due to yin deficiency and excessive fire; thin, soft, hard and brittle nails are due to insufficient liver blood; those with atrophic nails are mostly due to insufficient heart and spleen; those with vertical stripes are weak; those that are easy to break are those with weak heart and yang; those with a flat nail body The body is weak and sick, and those with upturned nails are deficient in both qi and blood; those with triangular nails are prone to stroke; those with eagle-claw-shaped or uneven nails are mostly due to qi stagnation and blood stasis, chest numbness, wind paralysis, and tendon twins; those with cylindrical nails are more likely to have carbuncles. People with scabies are prone to certain tumors; those with long claw nails are usually weak; those with concave nails are mostly due to kidney deficiency. Fan-shaped incarcerated nails are mostly due to hepatic deficiency, yin deficiency and yang hyperactivity, which are prone to stroke; nails that drop sharply on the side are prone to heart and blood stasis; a deep groove on the body of the nail indicates a serious illness or mental shock not long ago; eating nails Those with protruding faces are mostly due to spleen deficiency; those with obviously narrow nails are prone to Zangzang syndrome; those with narrow and long nails are prone to rheumatic paralysis; those with broad and bluish nails are mostly due to qi deficiency and blood stasis; those with dull nails and obvious vertical lines are mostly due to coughing Asthma; those with short nails are mostly caused by lack of heart energy and chest obstruction (especially those without a healthy circle); those with wide and short nails are mostly caused by gynecological diseases and obstruction (if they lack luster, it is often caused by infertility); those who are very short are prone to cough Asthma.

Nails are a barometer of baby’s health

You can tell your health from your nails, right? What do healthy nails look like?

The nail is also called the nail plate. The front end is the fingertip, and the rear part under the skin is called the nail root. The tissue under the nail root is called the nail mother, which is where the nail grows. The skin covering the nail plate is called the nail profile. The semicircular light-colored area in front of the nail profile is the nail half moon, which can be regarded as a sign of health. Normal baby nails are pink, very smooth and tough, and the color of the nail half moon is slightly lighter.

Judging whether your baby's nails are healthy depends on many aspects such as their surface shape, color, texture, thickness and relationship with the nail bed.

Abnormal color

Leukonychia, white spots appear on the baby's nail plate, superstitiously called 'lucky spots', medically called 'spotted leukonychia'; if there are rampant White lines or small white spots, or even the entire nail turns white, are called 'linear leukonychia', 'partial leukonychia', and 'complete leukonychia'. A' is more common in normal children, or is a temporary injury.

Yellow nails are when the entire nail turns yellow, mainly due to eating carotene foods. Yellow nails can also appear due to fungal infection, but they are often accompanied by changes in the shape of the nails. There is also yellow nail syndrome, a hereditary disease that is familial and often accompanied by edema of the face and limbs.

Others, such as green armor and black armor, are relatively rare.

If the color of the baby's nail and half moon is abnormal, it is mostly due to heart disease when it is red, and light red when it is anemic.

Abnormal morphology

If a child's nails have transverse grooves, it may be an acute febrile disease (such as measles, lung fever, scarlet fever, etc.), metabolic abnormality or skin disease.

If several rows of vertical shallow grooves appear in the center of the nail plate, it is seen in damage to the nail matrix and the skin disease lichen planus.

The nail plate becomes thin and brittle, with vertical protruding edges, and the nail tips are easy to tear and delaminate. This is a symptom of nail dystrophy and is also seen in skin diseases such as lichen planus.

Small dimples appear on the surface of the nail plate, which can occur in normal children or in children with psoriasis (also known as "psoriasis"), eczema and other skin diseases.

Longitudinal rupture of nails can be seen in hypothyroidism, abnormal function of the anterior pituitary gland, etc.

Abnormal hardness

When the nail is hard, the nail plate becomes thicker and thicker as it reaches the fingertips. This can be caused by congenital reasons or acquired due to long-term stimulation.

With soft nails, the deck is thin and soft, easy to bend and turn white, and the nail tip is easy to split. It is seen in congenital abnormalities, vitamin B deficiency, syphilis, etc. Flat nails, spoon-shaped nails, hook-shaped nails, giant nails, small nails, onychomycosis, etc. are mostly caused by congenital abnormalities, and clubbed nails are caused by both congenital factors and acquired heart disease.

Principles of nail diagnosis

Traditional Chinese medicine believes that the claws are for the liver and gallbladder in addition to tendons. Wait outside. The liver stores blood and regulates diarrhea. Therefore, Wangjia can detect the rise and fall of qi and blood in the internal organs, as well as their circulation.

The nail bed under the nail plate is covered with peripheral capillaries and nerve endings. Information about the body's blood circulation can be obtained by observing the changes in capillary morphology and blood flow status on the nail bed. According to modern microcirculation theory, cardiovascular and cerebrovascular diseases can be diagnosed from changes in the microscopic blood vessels on nails.

Human nails can reflect information about the body's health or disease. Our ancestors discovered through long-term in-depth and careful observation and repeated verification that the ten fingernails of both hands reflect diseases that have both similarities and differences, and there are certain patterns.

Generally speaking, thumb nails mostly reflect lesions of the head and neck; index finger nails reflect lesions between the head below the diaphragm and above (including the upper focus, chest, heart, lungs, etc.); middle finger nails reflect lesions between below the diaphragm and the navel. (middle burner, liver, gallbladder, spleen, stomach, etc.); the ring fingernails reflect lesions from below the umbilicus to the second yin (lower burner, kidney, bladder, intestine, etc.); the little finger nails reflect lesions below the second yin and lower limbs (the second yin) , lower limbs, etc.). From the perspective that fingernails represent the entire body, some people call them nail embryos ("holograms"). When shaking hands, the body parts represented by the five fingernails together look like an embryonic baby.

In addition to different fingernails representing different body areas and organs, people have also found that different areas of each nail also reflect different parts of the human body. Each nail is divided into five areas, representing different parts of the body. Due to space limitations, we will not go into detail here.

Methods for nail diagnosis

The person being examined should wash their nails, and those with stained nails should remove the stain. Under natural light, ask the subject to stretch out his hand naturally, with his palm facing down, and place it flat on the table. The examiner carefully observes the nail plate, nail half-lunar arc, nail bed, nail groove folds, etc., and pays attention to changes in the color, thickness, unevenness, patches, lines and other shapes of the nails.

Deck: Pay attention to its transparency, color, luster, size and thickness, flatness and unevenness, soft, hard, tough, brittle, smooth or rough texture, etc.

Half-moon arc: observe its size and color.

Nail bed: Use your fingers to press the nail plate and check the shape, markings, petechiae, color and vein dynamics of the nail bed through the nail layer.

Nail folds (nail folds): Pay attention to its shape, color, dynamics of collaterals, and whether the combination with the nail plate is regular and defective.

Distinguish nail color

White: Pale nail bed indicates Qi and blood deficiency. The disease is mild if it is white and moist, and the disease is serious if it is white, withered, dull and rough. Pannail pallor is common in anemia, malnutrition, cirrhosis, chronic colitis, onychognathism, Raynaud's disease, pulseless syndrome, etc. Some leukonychia can be seen in tuberculosis, nephritis, lymphosarcoma, and cancer. Punctate leukoonychia (one or several white spots of varying sizes or white cloud-like or white flocculent spots appearing on the deck) may indicate digestive system diseases, malnutrition, zinc deficiency, syphilis, etc.

Red: Red nail bed indicates Qi and blood heat syndrome. If the nail bed is red and moist, the disease will be mild and mild. If the nail bed is red and withered, the disease will be severe and severe. Nail bed bleeding is also classified as red nail. If spindles appear on the free edge of the nail to form longitudinal linear bleeding, it can be seen in coagulation disorders, drug allergies, subacute endocarditis, etc.

Yellow: The nail bed is yellow, indicating damp and heat fumigation. Yellow and bright, indicating mild disease and short course. Dark yellow indicates serious illness and long course of disease. Yellow nails can be seen in hepatobiliary diseases, hemolysis, hypothyroidism, chronic adrenal insufficiency, nephrotic syndrome, carotenemia, etc.

Cyan: The nail bed turns blue, indicating cold syndrome, blood stasis, pain syndrome, and convulsions. Seen in hypoxia or the use of adipine and phenolphthalein. Green and haggard nails after a long-term illness indicate that the liver qi will disappear and the prognosis is poor.

Black: Black nail bed, mainly cold syndrome, blood stasis, and pain syndrome. The appearance of black nails that are withered and dull due to long-term illness indicates that the kidney qi will be extinguished, and the disease is dangerous. The appearance of one or several thin and black vertical lines on the nail surface indicates endocrine disorders, which can be seen in menstrual disorders, dysmenorrhea, malignant tumors, radiation sickness, etc. After cancer patients undergo radiotherapy and chemotherapy, each course of treatment can form a black mark on the nail, recording each course of treatment in circles.

Blue: It means the liver is affected by evil and blood stasis is blocked. Modern research has found that oral administration of chloroquine, adipine, hemochromatosis, hepatolenticular degeneration, nitrite poisoning, and hypoxia can cause blue armor.

Brown nails: Common in acanthosis nigricans, adrenal insufficiency, or oral administration of phenolphthalein, antimalarial drugs, etc.

Red and white to half nail: The distal end of the nail is reddish brown, and the proximal end of the nail plate is glassy white, with clear boundaries. It is common in cirrhosis and azotemia.

Identification of nail morphology

Atrophic type: People with this type of nails have overly sensitive nerves, react strongly to various stimuli, and often have clinical manifestations of malnutrition.

Hypertrophic shape: People with this shape of nails often suffer from slow sensation, are prone to limb paralysis, are prone to wind and cold, and often have a history of low back and leg pain.

Long shape: People with such long nails are prone to respiratory and cardiovascular system diseases, such as tracheitis, pneumonia, tuberculosis, myocarditis, etc.

Short-shaped nails: People with short-shaped nails are prone to coronary heart disease, diabetes, neurasthenia and other diseases.

Triangular: The nail is narrow at the base and wide at the head. People with this type of nails often have a history of headaches.

Narrow shape: People with this shape of nails have poor physical constitution, but have strong disease resistance and strong tolerance.

Olive-shaped nails: People with this shape of nails are more likely to have atherosclerotic heart disease, high blood pressure, cerebral thrombosis, and are prone to brain tumors and myelopathy.

Fan-shaped nails: People with this shape of nails are prone to stroke. Clinically, they are also more common in patients with hepatitis and cholelithiasis.

Concave and transverse linear shape: People with this shape of nails may have parasitic diseases.

Hooked-up shape: The middle part of the nail is weak and there are horizontal lines on the nail. People with nails with this shape often suffer from hookworm disease, which indicates calcium deficiency, anemia or malnutrition in the body.

Medium-high index finger: It is shaped like an animal’s claws and is a sign of tuberculosis.

Semi-circular: People with this shaped nails often suffer from renal insufficiency.

Tubular shape: seen in patients with advanced cancer.

Flat-shaped nails: People with this-shaped nails are prone to lymphatic tuberculosis and throat diseases, such as pharyngitis, laryngitis, and acute suppurative tonsillitis.

Vertical lines: There are vertical lines on the nails and they are easy to break. People with nails with this shape mostly have poor heart function or weakened intestinal peristalsis. There are more vertical lines on the thumb nails, which may be caused by a partial eclipse.

Groove-shaped: There are deep grooves on the nails, which means that people with this-shaped nails have a large number of internal parasites or have intestinal paralysis. Grooves on the thumb nails often lead to depression; grooves on the index fingernails are prone to skin rashes; grooves on the middle nails indicate myasthenia; grooves on the ring fingernails are prone to eye diseases; grooves on the little fingernails Concave grooves are prone to hepatobiliary diseases, pharyngitis, neuralgia, etc.
