Once, there was a widespread rumor that went like this: the more moons on your nails the healthier you are! Afterwards, after all parties spared no effort to disprove the rumor, now we all know that this is complete bullshit. In fact, this conclusion is only a small step away from success – it’s not the number of crescents that acts as a barometer, but the changes in the crescents themselves! And it’s not just the crescent, other changes in the nails are also revealing to us changes in the condition of the body. 1, white crescent, not the number of changes in the nail “crescent” can indeed reflect the health status. However, it is not the number, but whether it has changed a lot recently compared to before. Generally speaking, the change of the “crescent” can reflect the metabolism of the human body. If compared with the previous crescent – bigger and more: the body’s metabolism is accelerated, so pay attention to hyperthyroidism; smaller and disappearing: the body’s metabolism is slowed down, so pay attention to hypothyroidism, etc. The more crescents on the nail, the healthier it is? 2, pestle finger Pestle finger, in addition to the end of the finger / toe become larger, the nail will also be changed, such as the nail surface curvature of the fingertip will be significantly larger. This abnormal change often takes many years to accumulate before it is formed. Mortar and pestle fingers and corresponding nail changes may indicate: certain lung diseases; inflammatory bowel diseases, cardiovascular diseases, liver diseases, and AIDS, etc. 3. Inverted nail, depressed like a spoon Inverted nail is also called “spoon nail” because it does look a bit like a spoon at this time, depressed and soft, and this “depression” can often hold a drop of water. In most cases, the appearance of the opposite nail may indicate: iron deficiency anemia; hemochromatosis: liver lesions (hemochromatosis) caused by the body absorbing too much iron from the diet; heart disease, hypothyroidism, etc. 4, nail depression There is a nail, its surface will appear a linear depression, this line in the medical known as Beau line. This line is medically known as the Beau line. An ingrown nail may indicate: trauma to the nail during growth, which can be interpreted as being “crushed” out; certain more serious diseases, such as diabetes, peripheral vascular disease; certain diseases that cause high fever, such as scarlet fever, measles, mumps and pneumonia, etc. 5, nail peeling Many anti-Japanese dramas have episodes in which revolutionary fighters are tortured by the enemy to peel their nails to obtain information. In fact, some diseases can also cause the nails to peel away from the nail bed, a phenomenon known as “nail separation”. The peeling nails are often white, yellow or green and opaque. Peeling nails are often seen in the following cases: trauma, forced separation, pain …… infection, taking certain medications or exposure to certain substances (such as adhesives), thyroid disease and psoriasis. 6. Terry’s nail The nail looks pale white with a narrow pink band at the tip of the finger. Nails that grow like this are called Terry’s nails. There are several possibilities for this kind of nail: normal elderly people will have this change because of aging; for example, liver disease, congestive heart failure and kidney failure, diabetes, etc. 7. Yellow nail syndrome The last type of nail change called “yellow nail syndrome” is that the nails become yellow, thicker, and grow slowly. There may also be a loss of the outer skin of the nail root, as if the nail has “molted” or even peeled off. The presence of yellow nails may indicate respiratory diseases such as chronic bronchitis or lymphedema. It’s amazing how many health secrets are hidden in a small nail. If you find yourself or someone around you has these abnormal changes in your nails, you must go to the hospital in time. Of course, stop counting your nails and saying “the more moon teeth, the healthier you are”.
