There are vertical stripes on the fingers, which seems to be a problem for many people. As long as there are vertical stripes, many people immediately get nervous. It is widely rumored in Jianghu that there are vertical stripes on fingers, which may be caused by intestinal problems, and some people say that vertical stripes on nails are a sign of malnutrition. Is it true?/You don't say. What exactly do vertical lines on nails mean?
In fact, the vertical line on the nail is medically called "nail longitudinal groove". For most people, it is actually lines, but the degree of expression is different. Some people are obvious, and some people are really superficial. This condition on nails has nothing to do with indigestion and nutritional deficiency. Please don't worry too much.
The surface of nails is never completely flat. If you look closely at everyone's nails, you will find that tiny vertical stripes are common, and almost no one's nails are as smooth as mirrors. Therefore, these small, inconspicuous longitudinal edges may not mean any health problems for us. The relationship between these vertical lines and health has no clinical data, nor is it scientific proof.
Phoebe Ritchie, a clinical professor of dermatology at Oregon Health University in the United States, believes that there are many reasons for vertical stripes on nails, but the most common reason is aging. People will increase the vertical lines of their nails with age, just like our wrinkles. This statement was endorsed by the American Academy of Sciences. Jessica Cront, a researcher, said: "Vertical lines, if evenly distributed throughout nails, are common and harmless, and are generally related to normal aging, because nails are increasingly unable to retain water." In rare cases, this may also be a sign of vitamin deficiency.
Therefore, vertical stripes will gradually appear with the increase of age, and become more and more obvious, just like skin wrinkles, generally do not need special treatment. The appearance of vertical stripes does not mean that your stomach is not good, nor does it mean that your constitution is poor. It just means that you do have vertical stripes on your nails.
