Does fingernail color half white and half red have any disease?

Healthy people have beautiful pink nails. ● Pale and bloodless nails indicate anemia, blood cold, loss of qi and blood, and low blood pressure. ● Purple nails indicate insufficient blood supply, hypoxia, arteriosclerosis and hyperlipidemia (high cholesterol). ● People who are close to death, nails tend to gradually turn black from the fingertips of the roots, grow into a straight line, and finally die. ● Blue nails lack oxygen. Too blue, congestion, or cardiac arrest are all malignant lesions of nails. ● Blue nails are severe cold syndrome and blood stasis. Blue and black are in critical condition. ● Yellow nails are suitable for jaundice, hepatobiliary diseases and smokers. It is a chronic disease, which appears on the thumb, suggesting that the whole body is in poor health. ● White spots on nails indicate calcium deficiency, silicon deficiency or parasites in the body. Drug or nicotine poisoning can also cause white spots. People with white nails are prone to fatigue or chronic habitual constipation. The white shift of the middle finger suggests that the spine is calcium deficient and osteoporosis, which is prone to waist and leg diseases or fractures and should not be repaired. There is a milky arc area at the root of a person's nail, commonly known as "half moon". Its size generally accounts for one-fifth of the nail, the thumb is the largest, the index finger is the second and the little finger is the smallest. People with this standard form show that their health is generally good. Fingers can't see "half moon": most of them have some problems in their circulatory system, which are prone to neurasthenia, anemia, hypotension and other diseases. "Half-moon shape" is too large to exceed one-fifth of nails: it means that the heart is overloaded and prone to cardiovascular diseases. "Half moon" is too small: it is easy to suffer from asthma, gout, pneumonia and gastrointestinal diseases. All four fingers are "half-moon-shaped", but the thumb is missing: it means that you are weak and prone to illness. There is no "half moon" on all four fingers, but the thumb has: it means that you are healthy, so don't worry. If the "half moon" turns blue, it means that the heart is sick. If the "half moon" suddenly shrinks, it disappears. This means that you may have a serious illness. You should go to the hospital immediately to treat people with short nails. The heart is weak, and it is easy to infect the waist and lower body from the abdomen. If the nail tip is flat and embedded in the meat, it may be prone to diseases such as neuralgia and rheumatism. People with narrow bones such as the lower half and spine are prone to get sick, especially those with very soft nails, and calcium is always very scarce. People with conchoidal nails should pay more attention to minor problems of the spinal cord and nervous system. Too many white spots on nails are symptoms of neurasthenia, and yellow spots indicate digestive system diseases. Small particles on nails are drug poisoning or parasites in the body. If the crescent moon at the bottom of the nail is big, it means that the blood circulation is fast. If it is small, it means that the blood circulation is not good. When it comes to extreme anemia, it will disappear completely in half a month. There is a straight line on the nail, which is proof of overwork and brain overload. At the beginning of a dangerous pathological state, the horizontal line is only exposed at the bottom of the nail, and gradually moves upward with the growth of the nail. People who are good at this can infer the possibility of illness from the position of the horizontal line. Put ten nails in the sun to observe, and move your fingers up and down. If there is shiny reflection on the nail surface, it means that the overall health is in an excellent state and the functions of various organs in the body are intact and normal. 2. Brown longitudinal stripes or cracks appear on the nail surface, extending from the fingertip to the root of the nail, suggesting intestinal inflammatory lesions or suggesting vitamin deficiency and iron deficiency. Partial whitening of nails indicates zinc deficiency. Ordinary whitish indicates anemia. Brown stripes appear on nails, which is a signal of liver disease. But it is worth noting that this tan stripe should appear on ten fingernails at the same time, which is liver disease; Isolated appearance cannot be used as a basis for diagnosis. 3, if there are many thimble-like pits on the nails, most of them are the late symptoms of psoriasis. 4, finger swelling, purple halo on the nails, probably lung disease. Thin, brittle or even cracked nails indicate that there are diseases in the respiratory and circulatory system. 5, the nail is invaginated in the middle, spoon-shaped, indicating that you have diabetes, anemia, hyperthyroidism or malnutrition. 6.

If the shape and color of nails are abnormal, it is a wake-up call for your health. Let's look at our nails again: from the shape of nails: 1, nails are flat, sunken, spoon-shaped, fragile and dull, which is a sign of liver water deficiency or iron deficiency anemia, hypopigmentation's anemia and light-colored small cell anemia. 2. The nails are parrot-shaped, and the fingertips are like drumsticks, which are more common in congenital heart disease with cyanosis, rheumatic heart disease, chronic heart failure, lung abscess, emphysema, silicosis, chronic fibrocavitary tuberculosis and chronic ulcerative colitis. 3. The appearance of horizontal stripes on nails is a precursor to the onset of nephropathy or myocardial infarction; The appearance of longitudinal stripes and lack of vitamin A are the precursors of liver disease. The appearance of pit lines is poor respiratory function. From the nail color: 1, the nail turns white, and hemorrhagic shock is an emergency; Chronic diseases can be seen in anemia, hookworm disease, gastrointestinal bleeding, advanced tuberculosis, pulmonary heart disease and so on. As white as ground glass, it is a characteristic of liver cirrhosis. 2, nails become white, thin and soft, more common in chronic wasting diseases.
