How to check nail health

We ordinary people can complete the preliminary screening of nail health at home in front of natural light. There is no need to go to the hospital to see the dermatology department. The core is to observe the three dimensions of nail shape, color and texture. If you find any abnormalities that you are not sure of, it is enough to go to a professional doctor for investigation.

I just persuaded my distant cousin to live with me a while ago. She posted a short video and said that vertical lines on her fingernails were a sign of a bad liver. She secretly bought liver-protecting tablets for two months and took them. When she came to my house, she held them out for me to see. I looked at the natural light from the window and saw that The very common longitudinal nail ridge was related to her daily exposure to dishwashing liquid while doing housework and the aging of her nail matrix. It had nothing to do with liver disease. Her liver protection tablets were stopped. Within two months, she said that she had been worrying and wasting money.

In fact, nails are a "hard business card" exposed to the body. Many small changes can indeed reflect problems, but you can't blame them all. Speaking of which, we have to mention the crescents that everyone is most concerned about. There is currently no unified conclusion in the academic field. Some clinical studies believe that the size and number of crescents are closely related to the basal metabolic rate. If the crescents are originally small and suddenly become larger, or if many crescents suddenly disappear, , accompanied by palpitations, fatigue, and sudden changes in weight, can lead to investigation of hyperthyroidism and hypothyroidism; however, many dermatologists believe that there are too many people who are born with small crescents or even no crescents on their entire hands. As long as there are no uncomfortable symptoms, there is no need to worry about the crescent moon.

Don’t turn on the warm yellow soft light in the bathroom when observing. It is easy to misunderstand the color. Normal and healthy nails are uniform light pink, with a natural luster on the surface. They are smooth to the touch and have no obvious bumps or layers. If you suddenly find a white spot on your nail, don't immediately label yourself as lacking calcium and zinc. In all likelihood, your nail hit the corner of a table, a crack in a door, etc. some time ago, and the nail matrix was slightly damaged. The white spot will disappear after two months when the nail grows to the tip of your finger and is cut off. Last month, I met a boy who was a sophomore in high school and came to see a doctor. He was very nervous as he clutched his hands and said that he had horizontal lines on his fingernails. He was worried that he was seriously ill. After asking for a long time, I found out that he had just had a flu with a temperature of over 39 degrees three weeks ago.

Of course, that doesn’t mean you don’t have to worry about changes in your nails. If your nails suddenly dent like a small spoon, or your nails become gray and thick, and flakes fall off when you pick them, and the nail groove around your nails is repeatedly red, swollen and pus-filled, don’t do it at home. Go to a dermatology department and get a dermatoscope. You can troubleshoot most of the problems for about ten yuan, which is much more reliable than searching online for a long time to scare yourself.
