What reason is fingernail sunken

summary

Recently, when I had a manicure, the boss said that my fingernails were sunken and looked very ugly. She suggested that I do nail care, but my friend advised me to go to the hospital for examination. She said that the sunken fingernails were related to my health. Don't get any diseases. I was very afraid. I believe many people find that their fingernails are sunken. Some think it's because they lack calcium, while others are afraid it's because they have grey nails. But after checking on the Internet, they find that it's not. So what's the reason for the sunken fingernails. Now let's get to know.

What reason is fingernail sunken

First: friends must know that nail indentation, also known as anti nail or spoon shaped finger, is a common disease in plateau area. The prevalence rate of hypoxemia in high altitude area is as high as 46%, while that in plain area is only 3%, which shows that the disease is closely related to high altitude hypoxemia. Hypoxia can cause the decrease of arterial oxygen partial pressure, lead to the hypoxia of peripheral blood circulation, cause the nutrient metabolism disorder of nail, and form nail depression.

Second: friends must pay attention to heavy physical labor. Among the people with nail depression, the heavy manual labor is more than the light manual labor, the right hand is more than the left hand, and the thumb, food and middle finger are more than the ring finger and little finger. It shows that under the same conditions, the labor intensity has a certain impact on nail depression. Labor intensity, finger oxygen consumption, can aggravate nail hypoxia.

Third: friends must understand the nutritional status, it was observed that long-term hunger, paralysis or fixed fingers and other factors can make nail growth slow. Nail indentation can occur in iron deficiency anemia and Raynaud's disease, which causes limb ischemia. It shows that there is a certain relationship between nail and nutrition. Cold factor: cold can make blood vessel constrict, blood flow speed slow down, aggravate peripheral tissue hypoxia.

matters needing attention

Friends must know that long-term exposure to cold water, low water temperature in high consumption areas, long-term contact of fingers with water, peripheral vasospasm and direct immersion of nails may be important causes of nail indentation. It has been investigated that the prevalence rate is high among washing workers, cookers, plasterers, housewives and farmers, and their hands have been exposed to water for a long time.
