What causes pits in nails?

The symptom of pits on the nails is very common in both adults and children, but what exactly causes the pits on the nails? Most people don't understand this. In fact, pits on the nails are related to the following 6 factors. The first reason is hypoxia.

1. What are the small pits on the nails?

The cause of nail pitting, also known as anti-nail or spoon-shaped nail, is not yet fully understood, but may be related to the following factors:

1. Hypoxia: Hypoxia can cause the body's arterial oxygen partial pressure to drop, resulting in hypoxia in the peripheral tissue blood circulation, causing nutritional metabolic disorders in the nails and forming nail depressions.

2. Heavy physical labor: Among people who suffer from nail depression, those who do heavy physical labor are more than those who do light physical labor. The intensity of labor has a certain impact on nail depression.

3. Nutritional status: Iron deficiency anemia and Raynaud's disease which causes acromial ischemia can both cause nail pitting. This shows that nails have a certain relationship with nutrition.

4. Long-term contact with cold water: Long-term contact of fingers with cold water, spasm of peripheral blood vessels and direct immersion of nails in cold water may also be the cause of nail depression.

5. Cold factor: The incidence of nail depression in people who work outdoors for a long time is significantly higher than that in other types of work.

6. Some people also believe that anti-A may be caused by abnormal cysteine ​​metabolism.

2. What should I do if there are small pits on my nails?

Small pits on the nails indicate a lack of calcium, protein, sulfur, and carotene in the body. At this time, you can make adjustments by supplementing the corresponding nutrients, such as eating carrots, eggs, and garlic. Milk, kelp, shrimp skin, animal bones, soy products, etc. are very helpful in supplementing calcium.
