Don’t underestimate the nails, dermatology clinic to see the nail disease patients accounted for one-tenth, do not come to see more, most of the nail disease is ringworm that is nail fungal disease commonly known as gray nails, mainly due to fungal infection. This is very affect the image, if not good, will gradually increase, so that the fingers and feet are infected, another common is nail dystrophy, uneven nails without luster, brittle cracking soft. This is related to nutritional metabolism and lack of trace elements and vitamins. There are different treatment options for both of these nail diseases. And more people are concerned about the lunula. A currently popular method of determining physical health. Does it have anything to do with physical health? Almost everyone has heard the saying that the more crescents you have on each hand the healthier you are, and the opposite means you are in poorer health, is this true? The crescent moon is actually the new growth of keratin The crescent moon on the nail is called the scientific name of the half-moon mark, some people call it half-moon white, underneath which is responsible for the production of nails of the “mother of the nail”, commonly found in the thumb, but the other nails are covered by the nail protection skin and less common. We all think nails are hard and strong, but they are actually made up of keratin, a part of the nail called the “nail matrix” where the flesh meets the nail plate, which is responsible for producing new keratin and transporting it outward so that our nails can grow properly. The newly created keratin is as white and full as a newborn baby, and as it makes its way out into the world (to the root of the nail where it becomes the official nail plate), it becomes hard and translucent and protects the delicate nail bed underneath. The nail matrix produces keratin fastest in the center and slower on both sides, but they all become translucent at the same time, so they form this curved white border, which we call the crescent moon. The relationship between crescent teeth and health Generally speaking, the size of the crescent teeth has little to do with health, if you are born with a more backward growth of the nail matrix, or the nail epithelium (that is, the layer of skin covering the root of the nail) is relatively wide and thick, or the growth rate of the nail is naturally slower, etc., will make your crescent teeth do not show up. It’s not true that more and bigger crescents mean you’re in better health. However, drastic changes in the number and size of crescent teeth should be taken into consideration when looking for thyroid problems. Although you can not rely on the crescent moon to recognize health, but if in a very short period of time, the crescent moon on your hand from no into a large and large, or had the crescent moon quickly disappeared, you really need to go to check the thyroid gland! When the thyroid gland is hyperactive, the metabolism of the whole body takes off with the added boost of increased thyroid hormones, and the nails grow rapidly as a result, and the nail guards can’t cover them completely, so your little white crescents come into their own your crescents get bigger and more numerous. Hypothyroidism is the opposite of hyperthyroidism, in hypothyroidism a person’s metabolism becomes very slow and the nails grow very slowly. They tend to be more likely to be completely covered by the nail care skin, and the original crescent moon will become smaller and smaller or even absent. On top of that, malnutrition and getting older can slow down the metabolism and make the crescent moon smaller or even disappear. So if the change is not drastic, you don’t need to be too nervous. A little reminder: Most people’s fingernails are fine, but if the changes are drastic or you’re not sure what the cause is, ask your dermatologist about it, and don’t ignore your body’s real distress signals.
