What is a crescent? What are the reasons for the disappearance of the half-moons on fingers?

The lunula generally refers to the half-moon shape near the base of the nail. The disappearance of the lunula may be caused by malnutrition.

1. The half-moon is a common phenomenon, which is characterized by a white substance shaped like a half-moon near the root of the nail. The half-moon may not be completely keratinized, but everyone's physique is different. A few people may not have a half-moon on their fingers, which is usually related to daily lack of qi and blood or digestive problems.

2. If the half-moon on the nail has obviously disappeared, it may be due to lack of vitamins or trace elements caused by excessive fatigue, frequent picky eating, malnutrition, or it may be due to deficiency of Qi and blood. However, the disappearance of the half-moon does not mean anything. You can go to the hospital for a trace element test and check your physical condition at the same time.

3. The speed of nail growth or whether the nail surface is smooth are largely affected by the individual. If there is obvious roughness, it may be caused by calcium deficiency in the body. You need to take some calcium tablets orally in time. At the same time, you can also get more sun exposure, which is beneficial to the body's absorption of calcium.

Pay attention to nutritional diversity, a combination of meat and vegetables, take good care of local nail care measures, avoid prolonged contact with some chemicals, and wash your hands frequently.
