What is the white half-moon on the fingernail?

We often see some white half-moons on our fingernails, which sometimes appear and sometimes disappear, so we are quite curious about the white half-moons on our fingernails. At the same time, some people say that the white half-moons on the fingernails are related to our physical health.

The white half-moon on the nails is actually the tissue that grows outward from the nail, which is medically called the nail matrix. Most of the methyl group is buried under the skin, with only a small part exposed. Some fingers are exposed more, some are exposed less or cannot be seen, this is normal.

The nail is an immature nail cell and is normally white. As the nail cells grow, they become harder and more transparent.

The color of the "crescent" will change due to some diseases, and is medically used as one of the diagnostic signs of these diseases. For example: some cardiopulmonary diseases, high blood pressure, etc. will make the color of the "crescent" darker and redder; heavy metal poisoning will make the "crescent" black or green; and some diseases such as vitamin deficiency will make the "crescent" appear yellow, gray, etc.; some bacterial or fungal infections can also cause the color of the "crescent" or even the entire nail to change.

People with short nails have weak hearts and are easily infected by diseases from the abdomen to the waist and lower body. If the tip of this kind of nail is flat and embedded in the flesh, it may cause neuralgia, rheumatism and other diseases.

People with narrow lower part of nails are more susceptible to diseases of spine and other bones, especially those with very soft nails, who are always very calcium deficient.

People with shell-shaped nails should pay extra attention to minor problems with the spinal cord and nervous system.

Too many white spots on the nails are symptoms of neurasthenia, while thin yellow spots indicate a digestive system disease. Small grains on the nails are a sign of drug poisoning or parasites in the body.

However, it should be noted that although the "crescent" will show some symptoms due to illness, its role should not be exaggerated, and its apparent changes should not be used to make unfounded inferences about health conditions. If the color of the "crescent" changes abnormally, it is best to consult a doctor.

What diseases can be seen from the white crescent on the fingernails

1. Beau's lines: Horizontal grooves on the nails indicate malnutrition or a serious illness that temporarily affects nail growth, such as measles, rib inflammation, or a sudden heart attack.

2. Thali's nails: Most of the skin under the nail turns white, leaving only a small part near the tip of the nail that remains normal pink. This may indicate cirrhosis of the liver.

3. Yellow nail syndrome: The growth rate of nails slows down and they become thick and hard; they are yellow or green. Causes include chronic respiratory diseases, thyroid diseases or lymphatic diseases.

4. Bleeding: If these longitudinal red lines appear on the nails, it indicates microvascular 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.

5. Rows of pits: The surface of the nails becomes like the surface of copperware hammered by a coppersmith, sometimes caused by alopecia areata. This is an immune disease that is not well understood by the medical community and can cause partial or complete loss of hair.

6. Brown or black spots: These spots, especially those that extend from the nail to the surrounding finger tissue, may indicate melanoma. They may be a single large patch or a cluster of smaller spots, and are most common on the thumb and big toe.

The above is some relevant information about the white crescent on the fingernails. I hope it can help you better understand the white crescent. I wish you all a happy life.
