Fewer fingernail meniscus may be caused by individualized differences.
The crescent on the nail is called a semilunar scar, a product of methyl synthesis, the main component is keratin, synthesized by the body’s methyl. Located at the junction of the end of the nail and the skin of the finger, the nail grows as keratin is synthesized from the methyl group, and the final one becomes keratinous. The crescent often appears curved and pale white.
There are some individualized differences in the formation of the crescent moon. Generally, people with faster metabolisms have faster nail growth, so it is easier to form the crescent moon. The crescent on the finger is not necessarily related to health, but if there was a crescent and disappeared within a short period of time, it may be related to the patient’s thyroid function abnormality, anemia, and staying up all night.
It is recommended to pay attention to diet and nutrition, avoid exertion and develop good living habits. If there is a sudden disappearance of the crescent, you can go to the hospital for a relevant examination, and follow the doctor’s instructions for treatment.
