What does the crescent on the finger represent?

In life, people's nails may have many problems. Nails are a barometer of human health. First of all, we must protect our nails and never over-do manicure, etc. In addition, we must closely observe the changes in indicators, such as white spots on the nails or vertical breaks in the nails. In addition, if you observe carefully, you will find that there are half-moons on the nails, which are white semicircular areas. So what is the saying about the human half-moon?

What does the crescent on the finger represent?

Judging from the shape of the nails: the nails are flat, concave, spoon-shaped, brittle and dull, which are signs of insufficient liver water or iron deficiency anemia, hypochromic anemia and light-colored microcytic anemia. The nails are parrot-beak shaped and the fingertips are like drumsticks. They are often seen in congenital heart disease with cyanosis, rheumatic heart disease, chronic heart failure, lung abscess, emphysema, silicosis, chronic fibrous cavitary tuberculosis, chronic ulcerative colitis, etc. The appearance of horizontal lines on the nails is a precursor to kidney disease or myocardial infarction; the appearance of vertical lines is a precursor to liver disease; and the appearance of sunken pits indicates poor respiratory function.

Judging from the color of the nails: if the nails turn white, acute conditions include blood loss and shock; chronic conditions include anemia, hookworm disease, gastrointestinal bleeding, late-stage pulmonary tuberculosis, cor pulmonale, etc.; if the nails are as white as frosted glass, it is a characteristic of liver cirrhosis; if the nails turn white, thin and soft, it is more common in chronic wasting diseases. Yellow nails are caused by a lack of vitamin E, which is seen in hypothyroidism, carotenemia, nephrotic syndrome, etc. If your nails turn gray, you may be suffering from onychomycosis. Purple nails with small red thorns are caused by lack of oxygen and indicate heart and lung disease. If your nails are half red and half white, it means your kidney function is poor. White spots or floc-like white spots on the nails may indicate zinc deficiency, gastrointestinal disease, or anemia; black spots or blue spots are a sign of poisoning; red spots around the nails are more common in patients with lupus erythematosus and dermatitis. If the lunula is blue, it indicates poor peripheral circulation; if it is obviously red, it is a sign of heart failure; if the lunula is obvious, the intestinal absorption is good; if there is no lunula or it is narrow, the digestive ability is poor.

Nails are indeed a window into human health, so we should always pay attention to their changes, especially those who do long-term manicures. We should also remember to give our nails a break from time to time to let them show their true appearance. If you find multiple nail mutations, you should seek medical attention in time.
