What is the matter with nails concave inwards

Everyone's nails have different shapes, and at the same time, the shape of nails can also reflect a person's physical health to a certain extent. For example, if white spots appear on the nails for no apparent reason or there are vertical lines on the nails, it indicates that there is something wrong with a person's body. At this time, one should go to the hospital for a comprehensive examination in time. So if a person finds that his nails are sunken inward, what disease could it be?

From the shape of the nails:

1. Flat, concave, spoon-shaped, brittle and dull nails are signs of insufficient liver water or iron deficiency anemia, hypochromic anemia and light-colored microcytic anemia.

2. The nails are in the shape of a parrot's beak and the fingertips are like drumsticks. This is 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.

3. Horizontal lines on the nails are a precursor to kidney disease or myocardial infarction; vertical lines on the nails indicate a lack of vitamin A and are a precursor to liver disease; sunken pits on the nails indicate poor respiratory function.

From the color of nails:

1. Nails turn white. Acute conditions include blood loss and shock. Chronic conditions include anemia, hookworm disease, gastrointestinal bleeding, advanced tuberculosis, cor pulmonale, etc. If the nails become as white as frosted glass, it is a characteristic of liver cirrhosis.

2. Nails become white, thin and soft, which is often seen in chronic wasting diseases.

3. Yellow nails are caused by a lack of vitamin E. Traditional Chinese medicine believes that it is mostly caused by the fumigation of damp heat, and is seen in hypothyroidism, carotenemia, nephrotic syndrome, etc.

4. When nails turn gray, it is a sign of onychomycosis. In the early stage, there will be itching around the nails, and then the nails will become deformed, lose their luster and become grayish white.

5. Purple nails with small red thorns are caused by lack of oxygen and indicate heart and lung disease.

6. If the nails are half red and half white (commonly known as yin-yang nails), it means that the kidney function is poor.

7. White spots or floc-like white spots on the nails may indicate zinc deficiency, gastrointestinal disease, or anemia; the appearance of black spots or blue spots is a sign of poisoning.

8. Erythema appears around the nails, which is more common in patients with lupus erythematosus and dermatomyositis.

9. If the lunula of the nail is blue, it indicates poor peripheral circulation.

10. If the lunula is obviously red, it is a sign of heart failure; if the lunula is obvious, the intestinal absorption is good.

11. Those with no lunula or a narrow one have poor digestive ability. For those who do manicures for a long time, don’t forget to give your nails a break every once in a while to let their true appearance show. If you find multiple nail changes, you should seek medical attention immediately; if only one or two nails have changes, there is no need to panic, as it may be caused by trauma.
